Graduate School Letter of Recommendation Examples 2022-2023

Grad school recommendation letters are an essential part of every graduate school application package–even in this (almost) post-COVID era of remote work and Zoom classes. Nearly all applications to graduate school still require at least two recommendation letters from individuals who can discuss your abilities, competencies, and personal character in a coherent way and recommend you for admission to graduate school.

Many referees have difficulty writing these recommendations themselves (for language issues or simply because they are busy) and some rely on the applicant to pen the draft of the letter and receive confirmation before submitting it to the graduate school. But regardless of who is writing the letter, there are a few key elements the recommender needs to include to craft a stellar recommendation for their graduate candidate.

Who should write a recommendation letter for graduate school?

Choosing which professors, supervisors, or advisors to request a graduate school recommendation letter from can be somewhat overwhelming. Should you choose someone who does not know you personally but who has connections to your target graduate school? If a famous professor writes you a grad school recommendation letter, will this automatically give you an advantage with the admissions committee? 

In general, graduate recommendation letters should come from people who know you well, who respect you enough to say glowing things about you as a student and researcher, and who hold positions in school or work that are above your own. At least one letter of recommendation should be submitted from a past or current professor or academic advisor. 

Another could be from someone in a slightly different role, including an employer, a research adviser, a senior colleague, or a professor from a different department or kind of class (e.g., a discussion class professor instead of a lecturer). No matter who it is, the recommender should know the applicant and recognize their accomplishments. It also helps if the recommender understands some details about the program to which their candidate is applying.

Here are some guidelines to follow when choosing who to ask for letters of recommendation for graduate school. Select someone who:

• Knows you well and can answer positively. Choose an individual who you have spent time with outside the classroom if possible. They should also be familiar with your career goals and hold a favorable view of you. 
• Has known you for quite a while. A recommendation letter for graduate school carries more influence if the person has known you for months or years instead of months. If you can, find someone who knows you from various contexts, such as a professor who is also your advisor. 
• Can speak to your strengths in relation to your graduate program. Choosing a finance professor to write your recommendation letter for an MBA program would be a good idea because they can write about the qualities that will aid you in pursuing an MBA (qualities you can also include in your MBA essay ) and a broader career in business. 
• Has substantive stories to share about you. Who was fortunate enough to see you succeed in an academic, extracurricular, or professional setting? Having someone write your LOR who has good stories to share about you is certainly going to benefit you more than someone whose class you took with two hundred other students. 

How to Request a Letter of Recommendation for Graduate School

Knowing how to request a letter of recommendation for graduate school can directly impact the quality of the letter your referee writes for you. Show respect and consideration for the time that your recommender is taking to write a glowing review that will get you into graduate school and positively impact the rest of your life. 

With this in mind, it may seem obvious that the very best way to ask for a letter of recommendation for graduate school is to do so in person. While this isn’t possible for all students (due to availability or schedule), it is the best route if you want to ensure that your LOR is not only written on time, but includes all the positive information about you that admissions committees want to see in a graduate candidate. When you cannot ask in person, sending an email is an appropriate second-best option. But remember to always be cordial and polite when making this request. 

What information should be included in a graduate recommendation letter?

Your referral letter should cover a range of skills, from academic abilities to research experiences, to applied experiences in and out of class. As the recommender, your letter should clearly answer some specific questions:

Your letter of recommendation should cover a range of skills, from academic abilities to research experiences, to applied experiences in and out of class. As the recommender, your letter should clearly answer some specific questions:

• What is your relationship with the student?
• Why should the graduate faculty listen to your opinion? (include your status, title)
• What makes this student special? (discuss their characteristics, qualities, traits)
• What specifically did this student do to impress you? (discuss their accomplishments, habits in class)
• What makes this student qualified for graduate school and for this program? (include specific courses or interests of the student in addition to abilities and traits)
• What do you know about the program the student is applying to?

What information does the LOR recommender need from me?

The recommender should be given sufficient time to write (and/or confirm) the letter. If it has been a while since you were last in contact, sending a background information file will make things easier. Include the following information so that the recommender can use a few details to bolster their letter:

• Classes the student has taken with the recommender
• Experiences you have shared
• Transcripts
• Research experience and internships
• Awards and achievements
• Academic/career goals
• Relevant professional experience

In addition to background information, make sure that the recommender has the necessary information to plan the writing in a timely manner and target the letter as much as possible:

• Graduate program application due date
• Copy of recommendation forms (if applicable)
• Instructions for submitting LORs (hard copy, soft copy, or direct to school)
• Details about the program and school the student is applying to

What style of writing should be used in a recommendation letter?

Although the letter of recommendation is more informal than academic writing, you should make sure that your language has no grammatical or mechanics errors and that it is of an academic level that reflects the author’s educational level and qualifications. Apply the following standards to the writing and the essay-drafting process:

• Make your language more personal in tone than research writing.
• Use the active voice and first-person point of view more often.
• Write chronologically, starting from important traits and then moving on to actions and achievements.
• Use lots of details—list course names, scores, and specific achievements of the student.
• Edit your letter before submitting it to the graduate admissions faculty.

How to Write a Grad School Letter of Recommendation Letter: LOR Outline

A well-structured recommendation letter (like any organized essay) will guide the reader logically towards an understanding of why this student is worthy not only of praise but of admission to graduate school. Grad school requires quite a few high-level scholastic attributes that not all students possess, and therefore it is important to focus on both the achievements of the candidate and on their personal character and potential to thrive in a difficult academic environment.

Use this outline as a letter of recommendation template in which to input your candidate’s achievements, skills, and traits. Note that the flow of information moves the reader into greater detail, using form phrases and transitions that increase the readability of the letter.

1. Greeting to the recipient

Dear {Name}, or To Whom It May Concern, To the graduate faculty of the {University / Department}

2. Opening paragraph: position; relationship to the applicant; general assessment of the applicant

It is my absolute pleasure to recommend {Name} for admissions to {Program} at {University}… I am a professor of {area of study} in the department of {department} at {University}.

3. Second paragraph: positive skill or trait; evidence of trait or skill; anecdotes demonstrating this skill

Jane has excellent communication skills. Her written work is both clear and concise, as well as interesting to read…

4. Third (up to fifth) paragraph: Other skills or traits; evidence of character and skills; detailed anecdotes

At a personal level, Jane is a well-disciplined, industrious student with a pleasant personality. She went well beyond the course expectations…

5. Final Paragraph: clear recommendation of the candidate to the specific school or program.

Jane is unquestionably an exceptional candidate for graduate study in {Program Applying for}. Jane’s work in “Developments in Anthropology” suggests that she would greatly benefit from the opportunities for intellectual development provided by a sustained period of graduate study…

6. Closing line: polite offer to be contacted if needed

If I can be of any further assistance, or provide you with any further information, please do not hesitate to contact me.

Letter of Recommendation Template and Useful Phrases

Admission essays often contain template phrases or “form phrases” that allow the writer to plug in their specific information while not spending too much time deciding how to compose every single aspect of the writing. This can be especially useful for ESL authors because conventional expressions used in academic and essay writing can be difficult to learn and memorize. Use the following form phrases to help craft a more professional letter of recommendation.

Introducing yourself

• My name is  {Author}  and I have been a Professor of Math at  {University}  since  {date} .
• I write to you today to proudly express my support for  {Student}  in applying to your prestigious university.

Discussing your relationship with the applicant

• I first came to know  {Student}  while teaching him/her in my  {Course Name}  course…
• I was  {Student} ’s thesis advisor during his/her senior year.
• I have known  {Student}  for several years now and can attest to his/her strengths and quality of character.

Discussing the student’s general positive traits

• {Student}  has excellent communication skills and displays them regularly in class discussions.
• He/She is a highly intelligent and competent student who excels in many areas.
• Not only is  {Student}  hard-working and thoughtful, but he/she also demonstrates kindness and generosity towards his/her peers.

Demonstrating evidence of student’s character and skills

• She/he has shown herself/himself to be a true leader who is able to successfully develop plans and implement them in his/her work.
• {Student}  demonstrated his/her independence daily, completing difficult lab exercises by researching outside of class.
• During his/her internship,  {Student}  consistently managed his/her work responsibilities diligently and learned quickly. For example…

Discussing the school/program the student is applying to

• As  {University}  is renowned for its  {Program} , I believe this is an ideal place for  {Student}  to solidify his/her abilities and cement his/her knowledge of  {area of study} .
• The learning environment that  {University}  is famous for creating excellent opportunities in which  {Student}  to apply his/her skills.

Final endorsement and offer to be contacted

• For the above reasons, I am confident that  {Student}  will make an excellent addition to your graduate program, and I wholeheartedly support him/her for admission to your program.
• Thank you for your time and attention in reading my endorsement.

Further Tips for Writing Admissions Essays

• Highlight your self-motivation, competence, and potential in this essay
• Emphasize everything from a positive perspective and write in the active voice.
• Demonstrate through examples; don’t just write that you are a “persistent person”—show it!
• Approach every topic with continuity and focus.

The Final Step: Editing Your Recommendation Letter

As any good writer knows, it takes more than one draft to create a strong and compelling work of writing. After you have written your recommendation letter draft, there is still a lot of room for revision. One way to ensure that grammar mistakes and style errors do not get in the way of a strong letter is to let the admissions experts at Wordvice’s Admissions Editing Services edit and proofread your (of your candidate’s) letter of recommendation or other application essays, raising the chances that your candidate will be admitted to the program of their choice.

Undergraduates need them for graduate-school applications; PhD students and postdocs use them to apply for fellowships and jobs; senior scientists often have to have them to apply for awards and promotions. But writing an effective and personal recommendation letter can be time-consuming, especially for academics who must juggle grant applications, manuscripts, teaching and student supervision. And some might struggle to say the right things to support a former employee or student in their career move, while sounding original and unique.

How to Write a Letter of Recommendation (Template + Tips)

Learn how to write a letter of recommendation, including tips on what to include and when to say no.

A letter of recommendation is a letter written on behalf of an applicant by someone who can vouch for that person’s educational or professional performance. This letter is typically sent to an admissions officer or hiring manager considering a candidate for admission, employment, or a scholarship.

Letters of recommendation help round out an application. They do this by offering insight into an applicant’s personal qualities like integrity, intellectual curiosity, or leadership potential. Writing a strong letter of recommendation as a teacher, counselor, manager, or co-worker can help give an applicant an edge over their competition.

Letter of recommendation template

Use this template to get you started on writing a properly formatted recommendation.

Letter of recommendation sample

Here’s an example of a strong recommendation letter written using the template above.

How to format a letter of recommendation

Different organizations have different recommendation letter requirements. Be sure to ask the requester about any specific guidelines. In general, a letter or recommendation can be broken down into the following sections:

Recipient Name

Recipient Title

Recipient Address

Greeting: Address the recipient by name if possible (Dear Ms/Mr).

Personal introduction: Begin the body of your letter by introducing who you are and your relationship to the applicant.

Recommendation: What makes the candidate a good fit? Offer specific examples of skills or qualifications that match the role.

Anecdote or example: Include a personal anecdote about what it’s like to work with the candidate. Include any workplace or people skills you’ve observed them to possess.

Closing: Give an overview of why you’d recommend this person.

Contact information: Provide your email address and phone number so the recipient can follow up.

Tips for writing a strong letter of recommendation

If you’re writing a recommendation letter, you likely want the candidate to have the best chance of getting a positive result. Here are some tips for writing a good letter that may stand out to admissions officers, potential employers, or anyone else reviewing the letter.

Do your research.

Find out what exactly the candidate is applying for. Ask them to provide:

A copy of the job description or academic program requirements 

Their resume

Any particular skills, achievements, or qualifications they’d like you to highlight 

This will help you focus your letter on the skills or qualifications that are specific to the role the candidate is applying for. 

Be specific.

Please feel free to use a template (like the one above) to guide your writing, but remember to make it personal. Use examples and specific details to illustrate why this person is the best candidate. Choose strong, accurate adjectives over general terms or cliches. 

Think about what the person reading the letter might want to know. Include details or insight that wouldn’t necessarily show up on a resume or application. Your letter should help the recipient get to know the person you are recommending.

Stay positive.

Your recommendation should confirm that this candidate is a strong contender for whatever they’re applying for. Demonstrate honest enthusiasm, and avoid any comments that could be construed in a negative light. If you can make a superlative comparison between this person and others you’ve worked with (e.g. “she’s one of the best student aides I’ve had the pleasure to work with in my career as a professor”), do so.

Keep it formal and concise.

Use a business letter format using a twelve point font size in either Arial or Times New Roman. Write your letter on your business or organization letterhead if possible. The recipient likely reads dozens if not hundreds of letters, so keep yours concise and to the point. Aim for at least one page but no more than two. 

Don’t be afraid to say no.

If you feel like you’re unable to offer a glowing recommendation for a candidate, it’s okay to say no. A mediocre endorsement can often do as much damage as a negative one. While it may feel uncomfortable, it’s perfectly acceptable to respectfully decline a request.

Follow the instructions.

You’re vouching for this person. Be sure to follow any specific submission guidelines carefully, and get your letter in on time (or early). If your letter makes a good impression, that will carry over to the candidate you’re endorsing.

How to ask for a letter of recommendation

Chances are that you’ll be asked to provide letters of recommendation as part of an application you’re submitting sometime during your education or career. This is particularly true when you’re applying for graduate programs. One or more letters of recommendation are almost always part of the application process.

How to write a letter of recommendation (with examples)

Jump to section

What’s a letter of recommendation?

Format of a letter of recommendation, tips for writing a letter of recommendation, letter of recommendation examples, how to write a letter of recommendation for a friend, start writing.

Sometimes, a former colleague pops up in your inbox to ask you for a favor. This time, it’s a letter of recommendation. If you loved working with this coworker, you’d jump at the opportunity to help them out.

There’s only one problem: you’ve never written a letter like that before. You don’t even know where to begin — it’s time to learn how to write a letter of recommendation.

Writing an effective letter of recommendation takes time, thoughtfulness, and insight into the person’s background and character. 

If you’re willing to write a letter for this person, you’re likely overflowing with praise for them. But how do you balance your high regard with professionalism? This article discusses what a letter of recommendation is and how to write an effective one. It also includes valuable examples to get you started.

A letter of recommendation highlights a person’s skills, knowledge, and experience to bolster an application. Someone who knows a candidate writes one of these letters to vouch for them, expressing why they’re the best person for the opportunity.

A professional letter of recommendation is usually addressed to a hiring manager, admissions committee, or potential employer. You might also need to write one for someone applying for any of the following:

A new home or apartment 

Scholarships, grants, or awards

A new job 

Fellowship programs 

Graduate or professional school programs

As the letter writer, your communication skills are tested since you’re responsible for painting a positive picture of this person. Someone you once managed might be changing careers ; they need you to highlight their transferable skills .

Your letter could include positive comments about how they have strong public speaking skills and experience juggling multiple deadlines simultaneously.

Research has shown that people referred for a job are 4x more likely to be offered it than those without a referral. While a recommendation isn’t necessarily an internal referral, these letters show that someone credible vouches for the letter’s subject to have this position. A good letter of recommendation can make or break an application.

Letter of recommendation versus letter of reference

Let’s not confuse a letter of recommendation for a reference letter. While a letter of recommendation focuses on skills, knowledge, and experience, a reference letter describes a person’s character. It’s when you describe their work ethic and personal qualities. Both letters require specific examples and details, but they address different aspects of a person.

A reference letter:

Used for generic reasons 

Doesn’t have to be for professional reasons

Provides an overview of a person’s character and qualities

A letter of recommendation:

Used for specific positions or opportunities

Includes details and examples

Written by someone in an authoritative position, like a former manager or professor

You could be a little rusty when it comes to formatting a letter — or maybe this is completely new to you. One CBS poll found that 37% of Americans said it's been over five years since they've written a personal letter , and 15% had never done it at all. Don't fret if you relate. It’s never too late to learn a new skill.

Writing a letter of recommendation requires you to flex your organizational skills . If that’s something you struggle with, you might benefit from a letter of recommendation template. We've got you covered. 

Here are five sections you should include in your letter:

Greetings: Keep this section short and sweet. This is where you address the recipient of the letter. Make sure you know how to spell their name and title properly, or write a general greeting like "To whom it may concern" or “Dear [University Name] admission committee.”

Introduction: In your introduction, explain who you are, your relationship to the candidate, and why you recommend them for the opportunity. Consider briefly explaining why you're writing this letter and hint at what you'll discuss further down.

Body of the letter: This section contains the most important information. It'll include an overview of the person's past experiences, skills, and industry knowledge. Make sure to share short personal anecdotes with details that illustrate their abilities. For instance, you might describe the person's communication skills by using an example of when they were part of a large research project you worked on together and had to communicate effectively with team members. 

Closing statement: A good letter needs a solid closing statement. It's your chance to summarize your points and highlight why you're giving this person a strong recommendation. Be succinct and thorough, but avoid repeating details.

Your signature: It's time to finish your letter. Add your signature and contact information at the very end to signal it's over.

Understanding how to structure your letter will help organize the writing process. Make sure you’re thoughtful with your words and pay attention to the details .

Here are five tips to consider when writing a letter of recommendation:

Collect all the necessary information before you begin writing

Keep a positive voice, but avoid clichés 

Tailor your tone to the situation 

Focus on highlighting the most important details

Proofread your letter several times

The things you include in a letter for someone hoping to gain admission into graduate school differ from someone trying to secure a job offer. Each letter follows the same format, but the details are different.

You may find that getting the first few words down is the hardest, and that's understandable. But once you start your introduction, the rest of the letter will follow suit.

Here are three examples of how to start letters of recommendation for different scenarios, plus a few things to keep in mind for the rest of the letter:

1. Recommendation letter for a job

It's my pleasure to recommend [Person's name] for the Data Scientist role at X Company. I was [Person's name] supervisor from 2011-2021 and valued their deep knowledge of software programs, time management skills, and prior experience.

Above all, their innovative problem-solving techniques helped our team excel on projects. I've watched their skills grow immensely and think they'd be an ideal candidate for the job.

Next, share detailed examples of the person's problem-solving techniques and expand on how much they've grown throughout the years. Finish the letter by telling this employer how lucky their company would be to have this candidate based on your examples and their skills. 

2. Recommendation letter for graduate school

I highly recommend [Person's name] for admission to the [program] at X University. I am a psychology professor at Y University and had the pleasure of teaching [Person's name] in [course code] during their bachelor's degree in nutrition.

[Person's name] stood out from the other students because of their ability to research topics with exceptional depth and use feedback to strengthen their knowledge on how best to present nutritional studies. They thrive in collaborative environments because of their superb teamwork skills and communicate effectively with peers and colleagues.

Consider finishing the letter by expanding on the candidate's research topics and explaining some of the reasons why they have good teamwork and communication skills. It will help to know more about the program they’re applying to and which strengths to emphasize.

Each admissions committee will have different criteria, so tailor your examples to reflect the skills they’ll need to succeed. 

3. Recommendation letter for a scholarship

I highly recommend choosing [Person's name] for your annual marketing scholarship. I'm a former coworker of [Person's name] from 2015-2022 and saw firsthand how skilled they execute marketing strategies and intuitively understand data to predict future trends.

[Person's name] started as an intern and has since secured a full-time paid position. In their time at X Company, they demonstrated exceptional leadership skills and a high level of professionalism, which is why they'd be an ideal candidate for your scholarship. They would represent your scholarship and their school with dignity and integrity. 

The body of your letter should include references to specific projects the person worked on and how they’ve become a great leader in the workplace to show the selection committee why they best meet the scholarship’s criteria.

If a friend has asked you to write them a personal letter of recommendation, it won’t be as professional in tone as a letter a former employee or manager requests. It will act more like a reference letter by leaning on their character while highlighting strengths and accomplishments.

Here are a few things to consider when writing a letter of recommendation for a friend:

Ask for details: It would be tough to provide specific examples without details about what you’re recommending them for. Asking your friend for details on where they’re applying will help you structure your letter and pack it with the most valuable information.

Explain your relationship: This doesn’t have to be long but describe how you know the person. Explain if you have a professional working relationship or if you’ve known each other since childhood. This gives you credibility as a letter writer. 

Share your contact information: Include ways for people to contact you for a potential follow-up. Consider using your work email address or LinkedIn profile.

You could encounter a situation where you don’t want to write a letter of recommendation for a friend. Whatever your reason is, don’t feel pressured to write a letter. Learning how to say “no” helps you solidify your boundaries and honor your values.

Learning how to write a letter of recommendation tests your organizational and communication skills. You need to be precise and articulate with your praise — and that’s not easy, especially if you’ve never written a letter of recommendation before.

These letters are for various purposes, like landing a job, getting into a school, or signing a lease agreement. No matter the purpose, these letters should meet the same guidelines. You’ll always benefit from being detailed, asking the person questions for greater clarity about the application, and including all necessary sections. 

Remember that writing a letter of recommendation requires your authentic self . You have to be honest with your recommendation and reasons for offering it. After you’ve written it, be proud of yourself. You’ve taken the time to do something kind for someone else, and kindness never goes out of style.

Elevate your communication skills

Unlock the power of clear and persuasive communication. Our coaches can guide you to build strong relationships and succeed in both personal and professional life.

Writing recommendation letters on behalf of students and other early-career researchers is an important mentoring task within academia. An effective recommendation letter describes key candidate qualities such as academic achievements, extracurricular activities, outstanding personality traits, participation in and dedication to a particular discipline, and the mentor’s confidence in the candidate’s abilities. In this Words of Advice, we provide guidance to researchers on composing constructive and supportive recommendation letters, including tips for structuring and providing specific and effective examples, while maintaining a balance in language and avoiding potential biases.

Introduction

A letter of recommendation or a reference letter is a statement of support for a student or an early-career researcher (ECR; a non-tenured scientist who may be a research trainee, postdoctoral fellow, laboratory technician, or junior faculty colleague) who is a candidate for future employment, promotion, education, or funding opportunities. Letters of recommendation are commonly requested at different stages of an academic research career and sometimes for transitioning to a non-academic career. Candidates need to request letters early on and prepare relevant information for the individual who is approached for recommendation [ 1 , 2 ]. Writing recommendation letters in support of ECRs for career development opportunities is an important task undertaken frequently by academics. ECRs can also serve as mentors during their training period and may be asked to write letters for their mentees. This offers the ECRs an excellent opportunity to gain experience in drafting these important documents, but may present a particular challenge for individuals with little experience. In general, a letter of recommendation should present a well-documented evaluation and provide sufficient evidence and information about an individual to assist a person or a selection committee in making their decision on an application [ 1 ]. Specifically, the letter should address the purpose for which it is written (which is generally to provide support of the candidate’s application and recommendation for the opportunity) and describe key candidate qualities, the significance of the work performed, the candidate’s other accomplishments and the mentor’s confidence in the candidate’s abilities. It should be written in clear and unbiased language. While a poorly written letter may not result in loss of the opportunity for the candidate, a well-written one can help an application stand out from the others, thus well-enhancing the candidate’s chances for the opportunity.

Letter readers at review, funding, admissions, hiring and promotion committees need to examine the letter objectively with a keenness for information on the quality of the candidate’s work and perspective on their scientific character [ 6 ]. However well-intentioned, letters can fall short of providing a positive, effective, and supportive document [ 1 , 3 – 5 ]. To prevent this, it is important to make every letter personal; thus, writing letters requires time and careful consideration. This article draws from our collective experiences as ECRs and the literature to highlight best practices and key elements for those asked to provide recommendation letters for their colleagues, students, or researchers who have studied or trained in their classroom or research laboratory. We hope that these guidelines will be helpful for letter writers to provide an overall picture of the candidate’s capabilities, potential and professional promise.

Decide on whether to write the letter

Before you start, it is important to evaluate your relationship with the candidate and ability to assess their skills and abilities honestly. Consider how well and in what context you know the person, as well as whether you can be supportive of their application [ 7 ]. Examine the description of the opportunity for which the letter is being requested ( Figure 1 ). Often you will receive a request by a student or a researcher whom you know very well and have interacted with in different settings – in and out of the classroom, your laboratory or that of a colleague, or within your department – and whose performance you find to be consistently satisfactory or excellent. Sometimes a mentee may request a recommendation letter when still employed or working with you, their research advisor. This can come as an unpleasant surprise if you are unaware that the trainee was seeking other opportunities (for instance, if they haven’t been employed with you for long, or have just embarked on a new project). While the mentee should be transparent about their goals and searching for opportunities, you should as a mentor offer to provide the letter for your mentee (see Table 1 ).

First, it is important to establish whether you are equipped to write a strong letter of support. If not, it is best to have a candid conversation with the applicant and discuss alternative options or opportunities. If you are in a position to write a strong letter of support, first acquire information regarding the application and the candidate, draft a letter in advance (see Box 1 ) and submit the letter on time. When drafting the letter, incorporate specific examples, avoid biases, and discuss the letter with the candidate (see Tables 1 – 2 for specific examples). After submission, store a digital copy for potential future use for the same candidate.

Key do’s and don’ts when being asked to write a letter of recommendation

Other requests may be made by a candidate who has made no impression on you, or only a negative one. In this case, consider the candidate’s potential and future goals, and be fair in your evaluation. Sending a negative letter or a generic positive letter for individuals you barely know is not helpful to the selection committee and can backfire for the candidate. It can also, in some instances, backfire for you if a colleague accepts a candidate based on your generic positive letter when you did not necessarily fully support that individual. For instance, letter writers sometimes stretch the truth to make a candidate sound better than they really are, thinking it is helpful. If you do not know the applicant well enough or feel that you cannot be supportive, you are not in a strong position to write the recommendation letter and should decline the request, being open about why you are declining to write the letter. Also, be selective about writing on behalf of colleagues who may be in one’s field but whose work is not well known to you. If you have to read the candidate’s curriculum vitae to find out who they are and what they have done, then you may not be qualified to write the letter [ 8 ].

When declining a request to provide a letter of support, it is important to explain your reasoning to the candidate and suggest how they might improve their prospects for the future [ 8 ]. If the candidate is having a similar problem with other mentors, try to help them identify a more appropriate referee or to explore whether they are making an appropriate application in the first place. Suggest constructive steps to improve relationships with mentors to identify individuals to provide letters in the future. Most importantly, do not let the candidate assume that all opportunities for obtaining supportive letters of recommendation have been permanently lost. Emphasize the candidate’s strengths by asking them to share a favourite paper, assignment, project, or other positive experience that may have taken place outside of your class or lab, to help you identify their strengths. Finally, discuss with the candidate their career goals to help them realize what they need to focus on to become more competitive or steer them in a different career direction. This conversation can mark an important step and become a great interaction and mentoring opportunity for ECRs.

Examine the application requirements

Once you decide to write a recommendation letter, it is important to know what type and level of opportunity the candidate is applying for, as this will determine what should be discussed in the letter ( Figure 1 ). You should carefully read the opportunity posting description and/or ask the candidate to summarize the main requirements and let you know the specific points that they find important to highlight. Pay close attention to the language of the position announcement to fully address the requested information and tailor the letter to the specific needs of the institution, employer, or funding organisation. In some instances, a waiver form or an option indicating whether or not the candidate waives their right to see the recommendation document is provided. If the candidate queries a waiver decision, note that often referees are not allowed to send a letter that is not confidential and that there may be important benefits to maintaining the confidentiality of letters (see Table 1 ). Specifically, selection committees may view confidential letters as having greater credibility and, value and some letter writers may feel less reserved in their praise of candidates in confidential letters.

Acquire candidate information and discuss letter content

To acquire appropriate information about the candidate, one or more of the following documents may be valuable: a resume or curriculum vitae (CV), a publication or a manuscript, an assignment or exam written for your course, a copy of the application essay or personal statement, a transcript of academic records, a summary of current work, and specific recommendation forms or questionnaires (if provided) [ 9 ]. Alternatively, you may ask the candidate to complete a questionnaire asking for necessary information and supporting documents [ 10 ]. Examine the candidate’s CV and provide important context to the achievements listed therein. Tailor the letter for the opportunity using these documents as a guide, but do not repeat their contents as the candidate likely submits them separately. Even the most articulate of candidates may find it difficult to describe their qualities in writing [ 11 ]. Furthermore, a request may be made by a person who has made a good impression, but for whom you lack significant information to be able to write a strong letter. Thus, even if you know a candidate well, schedule a brief in-person, phone, or virtual meeting with them to 1) fill in gaps in your knowledge about them, 2) understand why they are applying for this particular opportunity, 3) help bring their past accomplishments into sharper focus, and 4) discuss their short- and long-term goals and how their current studies or research activities relate to the opportunity they are applying for and to these goals. Other key information to gather from the applicant includes the date on which the recommendation letter is due, as well as details on how to submit it.

For most applications (for both academic and non-academic opportunities), a letter of recommendation will need to cover both scholarly capabilities and achievements as well as a broader range of personal qualities and experiences beyond the classroom or the laboratory. This includes extracurricular experiences and traits such as creativity, tenacity, and collegiality. If necessary, discuss with the candidate what they would like to see additionally highlighted. As another example of matching a letter with its purpose, a letter for a fellowship application for a specific project should discuss the validity and feasibility of the project, as well as the candidate’s qualifications for fulfilling the project.

Draft the letter early and maintain a copy

Another factor that greatly facilitates letter writing is drafting one as soon as possible after you have taught or trained the candidate, while your impressions are still clear. You might consider encouraging the candidate to make their requests early [ 11 ]. These letters can be placed in the candidate’s portfolio and maintained in your own files for future reference. If you are writing a letter in response to a request, start drafting it well in advance and anticipate multiple rounds of revision before submission. Once you have been asked by a candidate to write a letter, that candidate may return frequently, over a number of years, for additional letters. Therefore, maintain a digital copy of the letter for your records and for potential future applications for the same candidate.

Structure your letter

In the opening, you should introduce yourself and the candidate, state your qualifications and explain how you became acquainted with the candidate, as well as the purpose of the letter, and a summary of your recommendation ( Table 2 ). To explain your relationship with the candidate you should fully describe the capacity in which you know them: the type of experience, the period during which you worked with the candidate, and any special assignments or responsibilities that the candidate performed under your guidance. For instance, the letter may start with: “This candidate completed their postdoctoral training under my supervision. I am pleased to be able to provide my strongest support in recommending them for this opportunity.” You may also consider ranking the candidate among similar level candidates within the opening section to give an immediate impression of your thoughts. Depending on the position, ranking the candidate may also be desired by selection committees, and may be requested within the letter. For instance, the recommendation form or instructions may ask you to rank the candidate in the top 1%, 5%, 10%, etc., of applicants. You could write "the student is in the top 5% of undergraduate students I have trained" Or “There are currently x graduate students in our department and I rank this candidate at the top 1%. Their experimental/computational skills are the best I have ever had in my own laboratory.”. Do not forget to include with whom or what group you are comparing the individual. If you have not yet trained many individuals in your own laboratory, include those that you trained previously as a researcher as reference. Having concentrated on the candidate’s individual or unique strengths, you might find it difficult to provide a ranking. This is less of an issue if a candidate is unambiguously among the top 10% that you have mentored but not all who come to you for a letter will fall within that small group. If you wish to offer a comparative perspective, you might more readily be able to do so in more specific areas such as whether the candidate is one of the most articulate, original, clear-thinking, motivated, or intellectually curious.

Key do’s and don’ts when writing a letter of recommendation

The body of the recommendation letter should provide specific information about the candidate and address any questions or requirements posed in the selection criteria (see sections above). Some applications may ask for comments on a candidate’s scholarly performance. Refer the reader to the candidate’s CV and/or transcript if necessary but don’t report grades, unless to make an exceptional point (such as they were the only student to earn a top grade in your class). The body of the recommendation letter will contain the majority of the information including specific examples, relevant candidate qualities, and your experiences with the candidate, and therefore the majority of this manuscript focuses on what to include in this section.

The closing paragraph of the letter should briefly 1) summarize your opinions about the candidate, 2) clearly state your recommendation and strong support of the candidate for the opportunity that they are seeking, and 3) offer the recipient of the letter the option to contact you if they need any further information. Make sure to provide your email address and phone number in case the recipient has additional questions. The overall tone of the letter can represent your confidence in the applicant. If opportunity criteria are detailed and the candidate meets these criteria completely, include this information. Do not focus on what you may perceive as a candidate’s negative qualities as such tone may do more harm than intended ( Table 2 ). Finally, be aware of the Forer’s effect, a cognitive error, in which a very general description, that fits almost everyone, is used to describe a person [ 20 ]. Such generalizations can be harmful, as they provide the candidate the impression that they received a valuable, positive letter, but for the committee, who receive hundreds of similar letters, this is non-informative and unhelpful to the application.

Describe relevant candidate qualities with specific examples and without overhyping

In discussing a candidate’s qualities and character, proceed in ways similar to those used for intellectual evaluation ( Box 1 ). Information to specifically highlight may include personal characteristics, such as integrity, resilience, poise, confidence, dependability, patience, creativity, enthusiasm, teaching capabilities, problem-solving abilities, ability to manage trainees and to work with colleagues, curriculum development skills, collaboration skills, experience in grant writing, ability to organize events and demonstrate abilities in project management, and ability to troubleshoot (see section “ Use ethical principles, positive and inclusive language within the letter ” below for tips on using inclusive terminology). The candidate may also have a specific area of knowledge, strengths and experiences worth highlighting such as strong communication skills, expertise in a particular scientific subfield, an undergraduate degree with a double major, relevant work or research experience, coaching, and/or other extracurricular activities. Consider whether the candidate has taught others in the lab, or shown particular motivation and commitment in their work. When writing letters for mentees who are applying for (non-)academic jobs or admission to academic institutions, do not merely emphasize their strengths, achievements and potential, but also try to 1) convey a sense of what makes them a potential fit for that position or funding opportunity, and 2) fill in the gaps. Gaps may include an insufficient description of the candidate’s strengths or research given restrictions on document length. Importantly, to identify these gaps, one must have carefully reviewed both the opportunity posting as well as the application materials (see Box 1 , Table 2 ).

Recommendations for Letter Writers

• Consider characteristics that excite & motivate this candidate.
• Include qualities that you remember most about the candidate.
• Detail their unusual competence, talent, mentorship, teaching or leadership abilities.
• Explain the candidate’s disappointments or failures & the way they reacted & overcame.
• Discuss if they demonstrated a willingness to take intellectual risks beyond the normal research & classroom experience.
• Ensure that you have knowledge of the institution that the candidate is applying for.
• Consider what makes you believe this particular opportunity is a good match for this candidate.
• Consider how they might fit into the institution’s community & grow from their experience.
• Describe their personality & social skills.
• Discuss how the candidate interacts with teachers & peers.
• Use ethical principles, positive & inclusive language within the letter.
• Do not list facts & details, every paper, or discovery of the candidate’s career.
• Only mention unusual family or community circumstances after consulting the candidate.
• A thoughtful letter from a respective colleague with a sense of perspective can be quite valuable.
• Each letter takes time & effort, take it seriously.

When writing letters to nominate colleagues for promotion or awards, place stronger emphasis on their achievements and contributions to a field, or on their track record of teaching, mentorship and service, to aid the judging panel. In addition to describing the candidate as they are right now, you can discuss the development the person has undergone (for specific examples see Table 2 ).

A letter of recommendation can also explain weaknesses or ambiguities in the candidate’s record. If appropriate – and only after consulting the candidate - you may wish to mention a family illness, financial hardship, or other factors that may have resulted in a setback or specific portion of the candidate’s application perceived weakness (such as in the candidate’s transcript). For example, sometimes there are acceptable circumstances for a gap in a candidate’s publication record—perhaps a medical condition or a family situation kept them out of the lab for a period of time. Importantly, being upfront about why there is a perceived gap or blemish in the application package can strengthen the application. Put a positive spin on the perceived negatives using terms such as “has taken steps to address gaps in knowledge”, “has worked hard to,” and “made great progress in” (see Table 2 ).

Describe a candidate’s intellectual capabilities in terms that reflect their distinctive or individual strengths and be prepared to support your judgment with field-specific content [ 12 ] and concrete examples. These can significantly strengthen a letter and will demonstrate a strong relationship between you and the candidate. Describe what the candidate’s strengths are, moments they have overcome adversity, what is important to them. For example: “candidate x is exceptionally intelligent. They proved to be a very quick study, learning the elements of research design and technique y in record time. Furthermore, their questions are always thoughtful and penetrating.”. Mention the candidate’s diligence, work ethic, and curiosity and do not merely state that “the applicant is strong” without specific examples. Describing improvements to candidate skills over time can help highlight their work ethic, resolve, and achievements over time. However, do not belabor a potential lower starting point.

Provide specific examples for when leadership was demonstrated, but do not include leadership qualities if they have not been demonstrated. For example, describe the candidate’s qualities such as independence, critical thinking, creativity, resilience, ability to design and interpret experiments; ability to identify the next steps and generate interesting questions or ideas, and what you were especially impressed by. Do not generically list the applicant as independent with no support or if this statement would be untrue.

Do not qualify candidate qualities based on a stereotype for specific identities. Quantify the candidate’s abilities, especially with respect to other scientists who have achieved success in the field and who the letter reader might know. Many letter writers rank applicants according to their own measure of what makes a good researcher, graduate trainee, or technician according to a combination of research strengths, leadership skills, writing ability, oral communication, teaching ability, and collegiality. Describe what the role of the candidate was in their project and eventual publication and do not assume letter readers will identify this information on their own (see Table 2 ). Including a description about roles and responsibilities can help to quantify a candidate’s contribution to the listed work. For example, “The candidate is the first author of the paper, designed, and led the project.”. Even the best mentor can overlook important points, especially since mentors typically have multiple mentees under their supervision. Thus, it can help to ask the candidate what they consider their strengths or traits, and accomplishments of which they are proud.

If you lack sufficient information to answer certain questions about the candidate, it is best to maintain the integrity and credibility of your letter - as the recommending person, you are potentially writing to a colleague and/or someone who will be impacted by your letter; therefore, honesty is key above all. Avoid the misconception that the more superlatives you use, the stronger the letter. Heavy use of generic phrases or clichés is unhelpful. Your letter can only be effective if it contains substantive information about the specific candidate and their qualifications for the opportunity. A recommendation that paints an unrealistic picture of a candidate may be discounted. All information in a letter of recommendation should be, to the best of your knowledge, accurate. Therefore, present the person truthfully but positively. Write strongly and specifically about someone who is truly excellent (explicitly describe how and why they are special). Write a balanced letter without overhyping the candidate as it will not help them.

Be careful about what you leave out of the letter

Beware of what you leave out of the recommendation letter. For most opportunities, there are expectations of what should be included in a letter, and therefore what is not said can be just as important as what is said. Importantly, do not assume all the same information is necessary for every opportunity. In general, you should include the information stated above, covering how you know the candidate, their strengths, specific examples to support your statements, and how the candidate fits well for the opportunity. For example, if you don’t mention a candidate’s leadership skills or their ability to work well with others, the letter reader may wonder why, if the opportunity requires these skills. Always remember that opportunities are sought by many individuals, so evaluators may look for any reason to disregard an application, such as a letter not following instructions or discussing the appropriate material. Also promote the candidate by discussing all of their scholarly and non-scholarly efforts, including non-peer reviewed research outputs such as preprints, academic and non-academic service, and advocacy work which are among their broader impact and all indicative of valuable leadership qualities for both academic and non-academic environments ( Table 2 ).

Provide an even-handed judgment of scholarly impact, be fair and describe accomplishments fairly by writing a balanced letter about the candidate’s attributes that is thoughtful and personal (see Table 2 ). Submitting a generic, hastily written recommendation letter is not helpful and can backfire for both the candidate and the letter writer as you will often leave out important information for the specific opportunity; thus, allow for sufficient time and effort on each candidate/application.

Making the letter memorable by adding content that the reader will remember, such as an unusual anecdote, or use of a unique term to describe the candidate. This will help the application stand out from all the others. Tailor the letter to the candidate, including as much unique, relevant information as possible and avoid including personal information unless the candidate gives consent. Provide meaningful examples of achievements and provide stories or anecdotes that illustrate the candidate’s strengths. Say what the candidate specifically did to give you that impression ( Box 1 ). Don’t merely praise the candidate using generalities such as “candidate x is a quick learner”.

Use ethical principles, positive and inclusive language within the letter

Gender affects scientific careers. Avoid providing information that is irrelevant to the opportunity, such as ethnicity, age, hobbies, or marital status. Write about professional attributes that pertain to the application. However, there are qualities that might be important to the job or funding opportunity. For instance, personal information may illustrate the ability to persevere and overcome adversity - qualities that are helpful in academia and other career paths. It is critical to pay attention to biases and choices of words while writing the letter [ 13 , 14 ]. Advocacy bias (a letter writer is more likely to write a strong letter for someone similar to themselves) has been identified as an issue in academic environments [ 3 ]. Studies have also shown that there are often differences in the choice of words used in letters for male and female scientists [ 3 , 5 ]. For instance, letters for women have been found not to contain much specific and descriptive language. Descriptions often pay greater attention to the personal lives or personal characteristics of women than men, focusing on items that have little relevance in a letter of recommendation. When writing recommendation letters, employers have a tendency to focus on scholarly capabilities in male candidates and personality features in female candidates; for instance, female candidates tend to be depicted in letters as teachers and trainees, whereas male candidates are described as researchers and professionals [ 15 ]. Also, letters towards males often contain more standout words such as “superb”, “outstanding”, and “excellent”. Furthermore, letters for women had been found to contain more doubt-raising statements, including negative or unexplained comments [ 3 , 15 , 16 ]. This is discriminative towards women and gives a less clear picture of women as professionals. Keep the letter gender neutral. Do not write statements such as “candidate x is a kind woman” or “candidate y is a fantastic female scientist” as these have no bearing on whether someone will do well in graduate school or in a job. One way to reduce gender bias is by checking your reference letter with a gender bias calculator [ 17 , 18 ]. Test for gender biases by writing a letter of recommendation for any candidate, male or female, and then switch all the pronouns to the opposite gender. Read the letter over and ask yourself if it sounds odd. If it does, you should probably change the terms used [ 17 ]. Other biases also exist, and so while gender bias has been the most heavily investigated, bias based on other identities (race, nationality, ethnicity, among others) should also be examined and assessed in advance and during letter writing to ensure accurate and appropriate recommendations for all.

Revise and submit on time

The recommendation letter should be written using language that is straightforward and concise [ 19 ]. Avoid using jargon or language that is too general or effusive ( Table 1 ). Formats and styles of single and co-signed letters are also important considerations. In some applications, the format is determined by the application portal itself in which the recommender is asked to answer a series of questions. If these questions do not cover everything you would like to address you could inquire if there is the option to provide a letter as well. Conversely, if the recommendation questionnaire asks for information that you cannot provide, it is best to explicitly mention this in writing. The care with which you write the letter will also influence the effectiveness of the letter - writing eloquently is another way of registering your support for the candidate. Letters longer than two pages can be counterproductive, and off-putting as reviewers normally have a large quantity of letters to read. In special cases, longer letters may be more favourable depending on the opportunity. On the other hand, anything shorter than a page may imply a lack of interest or knowledge, or a negative impression on the candidate. In letter format, write at least 3-4 paragraphs. It is important to note that letters from different sectors, such as academia versus industry tend to be of different lengths. Ensure that your letter is received by the requested method (mail or e-mail) and deadline, as a late submission could be detrimental for the candidate. Write and sign the letter on your department letterhead which is a further form of identification.

Conclusions

Recommendation letters can serve as important tools for assessing ECRs as potential candidates for a job, course, or funding opportunity. Candidates need to request letters in advance and provide relevant information for the recommender. Readers at selection committees need to examine the letter objectively with an eye for information on the quality of the candidate’s scholarly and non-scholarly endeavours and scientific traits. As a referee, it is important that you are positive, candid, yet helpful, as you work with the candidate in drafting a letter in their support. In writing a recommendation letter, summarize your thoughts on the candidate and emphasize your strong support for their candidacy. A successful letter communicates the writer’s enthusiasm for an individual, but does so realistically, sympathetically, and with concrete examples to support the writer’s associations. Writing recommendation letters can help mentors examine their interactions with their mentee and know them in different light. Express your willingness to help further by concluding the letter with an offer to be contacted should the reader need more information. Remember that a letter writer’s judgment and credibility are at stake thus do spend the time and effort to present yourself as a recommender in the best light and help ECRs in their career path.

How to Write a Reference Letter (Template & Examples)

By Ammar Ahmed

Published: January 29, 2024

A reference letter serves as a formal endorsement of an individual’s skills, character, and achievements, typically penned by a former employer, colleague, or academic mentor. 

This guide aims to empower professionals with the tools and knowledge to craft effective reference letters, combining best practices with practical templates to streamline this essential task.

Types of Reference Letters

Understanding the different types of reference letters is crucial for professionals, as each type caters to specific contexts and highlights various aspects of an individual’s profile. Below, we explore three key types: Professional, Academic, and Character Reference Letters.

Professional Reference Letters

Professional reference letters are written by a previous employer, supervisor, or professional colleague. They focus on the applicant’s work experience, skills, and professional achievements. These letters are often required during job applications or for career advancement opportunities. 

These letters should detail the individual’s role, responsibilities, key accomplishments, and work ethic. It’s essential to mention specific instances where the individual demonstrated their skills and contributed to the organization’s success.

Academic Reference Letters

Academic reference letters are typically requested for educational pursuits, such as college admissions, scholarships, or academic awards. Written by teachers, professors, or academic advisors, these letters highlight the individual’s academic achievements, intellectual capabilities, and potential for future success in their field of study. 

They should reflect on the individual’s academic performance, participation in class, and any notable projects or research work. This type of letter often emphasizes the individual’s dedication, curiosity, and ability to overcome academic challenges.

Character Reference Letters

Character reference letters focus primarily on the personal attributes of an individual. They are usually written by someone who knows the person well but is not a family member, such as a mentor, family friend, or community leader. 

These letters are particularly important when assessing an individual’s suitability for a role that requires a high degree of trust and integrity. They should provide insights into the individual’s character, values, and behaviors, illustrating how these traits have been beneficial in various situations.

Letter of Recommendation Examples

In crafting a letter of recommendation, it’s essential to tailor the content to the specific needs and strengths of the individual. Whether it’s for a professional role, character assessment, or a remote work position, each letter should effectively highlight the candidate’s unique qualities and contributions. 

These examples are designed to provide a clear understanding of how to articulate a candidate’s abilities and achievements in a manner that resonates with the recipient, ensuring the letter is both compelling and relevant to the candidate’s desired opportunity.

Taylor Robinson Hiring Committee Chair Innovatech Solutions 321 Future St. Techville, TV 32167 April 5, 2024

Dear Mr./Ms. Robinson,

What to Include in a Reference Letter

When composing a reference letter, it’s essential to include certain key elements to ensure the letter is effective and provides a comprehensive overview of the candidate’s qualifications.

These elements include:

1. Sender’s Information

The sender’s information is a critical component of any reference letter, as it establishes the credibility and authority of the person writing the letter.

This section should be clearly outlined at the top of the letter and include the following details:

• Name: The full name of the individual writing the reference letter.
• Title or Position: The professional title or position of the sender, which adds weight to the reference. This should be the current title or the one held while working with the individual being recommended.
• Company or Organization: The name of the company or organization where the sender is employed or affiliated.
• Contact Information: Including an address, phone number, and email address is crucial. It not only offers a means for the recipient to verify the information or seek further clarification but also demonstrates transparency and openness.

2. Recipient’s Information

• Name: The full name of the recipient. If the recipient’s name is not known, a general title or department can be used, such as “Hiring Manager” or “Admissions Committee.”
• Title or Position: Including the recipient’s professional title or position helps in directing the letter to the appropriate person, especially in large organizations where multiple individuals may be involved in the decision-making process.
• Company or Organization: The name of the company or organization where the recipient works. This acknowledges the professional setting into which the candidate is seeking entry or advancement.
• Address: The full postal address of the company or organization. 

3. Salutation

The salutation in a reference letter is more than just a formality; it sets the tone for the communication and shows respect for the recipient.

Here are key elements to consider:

• A Formal Greeting: Begin with a formal greeting such as “Dear,” which is universally recognized as professional and respectful.
• Addressing the Recipient: If you know the recipient’s name, use it directly after the greeting, e.g., “Dear Mr. Smith,” or “Dear Dr. Jones.” 
• Inclusive and Respectful Language: If the recipient’s name or gender is unknown, use a neutral and inclusive salutation like “Dear Hiring Manager,” “Dear Selection Committee,” or “To Whom It May Concern”. 

4. Opening Paragraph

The opening paragraph of a reference letter is pivotal in establishing the context of your relationship with the candidate and setting the stage for the endorsement to follow.

Here are some elements to include in this initial section:

• Introduce Yourself: Start by introducing yourself to give the recipient an understanding of who you are. Mention your name and your professional position or title, as this adds credibility to your recommendation.
• Your Relationship with the Candidate: Clearly state your professional or academic relationship with the person you are recommending. This could be as their supervisor, colleague, professor, or mentor.
• Duration of Relationship: Include how long you have known the individual. This time frame helps the recipient gauge the depth and extent of your experience with the candidate.
• Purpose of the Letter: Briefly mention the purpose of your letter – to recommend the individual for a specific position, program, or opportunity. This sets a clear context for the rest of your letter.

5. Body Paragraphs

The body paragraphs are the core of the reference letter, where you provide detailed insights into the candidate’s qualifications, skills, achievements, and character.

Here’s how to structure this section effectively:

• Specific Examples and Details: Use concrete examples to illustrate the person’s skills and qualifications. For instance, if you are highlighting their leadership skills, mention a specific project they led and the positive outcomes that resulted from it.
• Highlight Relevant Experiences and Accomplishments: Discuss experiences that directly relate to the position or opportunity the individual is pursuing. For example, if they’re applying for a managerial role focus on instances where they demonstrated effective management skills.
• Unique Qualities or Strengths: Point out any unique strengths or qualities that make the individual stand out. This could include exceptional problem-solving skills, innovative thinking, or a strong commitment to teamwork.
• Personal Anecdotes or Stories: Including a brief story or anecdote can make your letter more engaging and memorable. This could be an instance where the individual overcame a significant challenge or went above and beyond in their role.
• Balanced Perspective: While it’s important to focus on positive attributes, offering a balanced perspective can add authenticity to your letter. If appropriate, you can mention areas where the candidate has shown growth during your relationship.

Remember, the goal of these paragraphs is to provide a vivid picture of the candidate’s abilities and character. Well-chosen examples and stories make your endorsement more convincing and help the recipient understand why the individual is an excellent fit for the opportunity.

6. Closing Paragraph

The closing paragraph of a reference letter is where you encapsulate your overall recommendation and express your support for the individual.

Here are some elements to include:

• Summarize Key Points: Briefly restate the most important qualities, achievements, or skills of the candidate that you have highlighted in the letter. This reinforces your endorsement and reminds the reader of the candidate’s suitability for the position or opportunity.
• Express Your Strong Recommendation: Clearly state your confidence in the candidate and your belief in their suitability for the role or opportunity. Use affirmative language like, “I highly recommend,” or “I am confident that,” to leave no doubt about your support.
• Offer to Provide Further Information: Indicate your willingness to provide additional information or clarification if needed. This shows your genuine support and readiness to assist further in the candidate’s application process.
• Contact Information Reminder: Although your contact information is already at the top, a brief reminder here ensures that it is easily accessible for the reader, should they wish to follow up with you.

7. Closing Salutation

Here’s how to conclude your letter appropriately:

• Use a Professional Closing: Opt for a formal and universally accepted closing phrase. Common examples include “Sincerely,” “Best regards,” or “Yours truly.” 
• Consistency with the Tone: Ensure that the closing salutation matches the overall tone of your letter. If your letter is highly formal, a closing like “Sincerely” is appropriate. For a slightly less formal tone, “Best regards” can be a good choice.
• Space for Signature: If you are sending a hard copy or a scanned version of the letter, leave space for your handwritten signature above your typed name. This personal touch adds authenticity to the document.
• Typed Name and Title: Below the signature space, type your full name and title again.

Tips for Writing Letters of Recommendation

Crafting effective letters of recommendation requires a delicate balance of showcasing the candidate’s strengths, providing specific examples, and employing persuasive language. Here are some valuable tips to help you navigate the intricacies of this crucial task.

Quantify Achievements

When writing a letter of recommendation, it’s powerful to quantify the candidate’s achievements. Use specific figures and statistics to illustrate their accomplishments. For example, instead of saying “significantly increased sales,” specify “increased sales by 30% over six months.” This provides concrete evidence of their capabilities and makes their achievements more tangible and credible. Quantifying contributions also helps the recipient gauge the scale and impact of these accomplishments, offering a clearer picture of the candidate’s potential.

Connect to the Position or Opportunity

Tailor the letter to the specific position or opportunity the candidate is applying for. Highlight skills and experiences that are directly relevant to the job requirements or academic program. For instance, if the candidate is applying for a leadership role, emphasize their successful team management experiences. This shows that you understand what the role entails and have thoughtfully considered how the candidate’s skills and experiences make them a good fit, making your recommendation more relevant and persuasive.

Include Keywords

Identify important terms in the job listing or academic program description, such as “project management,” “analytical thinking,” or “creative problem-solving,” and weave them into your letter. This not only tailors the letter to the specific role but also ensures it passes through any automated screenings, increasing the chance that your recommendation will be read by decision-makers.

Leverage Technology for Reference Letter Management

Utilize technology platforms for efficient reference letter management. For example, online reference request platforms simplify the process of requesting, writing, storing, and submitting letters of recommendation. These tools often offer templates, reminders, and the ability to submit letters directly to institutions or employers. 

Leveraging such technology can streamline the process, ensuring timely submission and organization of your reference letters, while also offering a secure way to manage sensitive personal information contained within these documents.

Students may need a letter of recommendation to land a job, secure an internship, or earn a spot in a competitive academic program. But to make a good impression on the recipient, a letter of recommendation must be more than just an enthusiastic endorsement—it must follow a specific format.

Whether you are a student who needs a letter of recommendation for an application, or you're writing an academic reference, here’s how to format your letter and what to include in the document. Plus, you’ll find a few samples to help guide your writing.

Key Takeaways

• Students can request recommendation letters from teachers, professors, and employers.
• Character references provide an endorsement of a student’s positive personal qualities, such as their work ethic, dependability, and enthusiasm.
• When requesting a recommendation letter, offer to provide a copy of your CV or resume, as well as a job description or program overview.

When you request a letter of recommendation (sometimes also called a letter of reference), be sure to give potential writers information on why you need the letter, and let them know why you think they are a good person to recommend you. For example, if you performed well in your professor's class and are asking them to write a recommendation for graduate school, tell them you enjoyed their course and felt your performance demonstrated your commitment to pursuing another degree program.

You might also provide the person with your most up-to-date resume or CV. These details will make it easier for them to write a personalized and targeted reference letter.

You should also provide all the information the person needs regarding how to submit the letter, what to include (if there are any requirements), and when it is due.

When writing a reference letter , be sure to explain how you know the student, and describe some of the qualities that make him or her a good candidate for the job or school. Use specific examples to demonstrate how the person has shown those qualities.

Focus on the specific job or school the person is applying for. Try to include qualities and examples that will help them get that position or get into that school.

Feel free to ask the person for whom you are writing the letter for more information. You might ask to see the job listing, their resume, or a list of their related coursework.

Contact Information If you’re writing a formal printed letter, include your contact information, as well as the recipient’s information, at the top of the letter.

Greeting If you are writing a personal recommendation letter, include a salutation to start your letter (Dear Dr. Smith, or Dear Ms. Jones, for example).

Paragraph 1: Introduction Explain why you're writing and how you are connected to the person you are recommending, including how you know them and for how long.

Paragraph 2/3: Why You're Writing Share information on the person you are writing about, including why they are qualified and what they have to offer. It's fine to include more than one paragraph to provide details of the student's academic and work performance. Including examples of how they have excelled is a good way to show how the person is qualified.

Paragraph 4: Summary Write a brief summary of why you are recommending the person. Mention that you "highly recommend" the person, that you "recommend without reservation," or something similar.

Paragraph 5: Conclusion Offer to share more information and let the reader know how to contact you (phone, email, etc.) for a follow-up conversation.

Letter Closing End your letter with a formal letter closing and your name and title. If you are mailing a printed letter, include your signature underneath your typed name: 

Signature (for hard copy letter)

If you’re sending an email, include your contact information in your signature. 

It is a good idea to review recommendation letter examples and templates before you write a recommendation letter or a request for a letter. They can help you decide what kind of content you should include in your document.

A letter template also helps you with the layout of your letter, such as how many paragraphs to include, how to sign the letter, and what elements you need to include (your contact information, for example).

While recommendation letter examples, templates, and guidelines are a great starting point, always tailor a letter to fit the particular situation

Emma Johnson Owner Café Bistro 72 Dock Street Pacifica, Oregon 97233

Dear Ms. Johnson,

Daniel Williams worked as a server and manager at Central College’s student café under my supervision for seven semesters, beginning in Spring 2019.

Over that time, I was consistently impressed with his customer service and people management skills, as well as his dedication and good humor. I've often said that if I could clone Daniel, I'd never have to worry about staffing problems again. He's a truly gifted server, fast on his feet, and able to remember complicated orders without using an order pad.

He’s also an innovator. Thanks to his suggestions, we revamped the café menu last year to focus on the most popular dishes and dropped some expensive, time-consuming menu items. The result was a 10% increase in profits.

Our customers love him. More than one has suggested that Daniel become a “super senior,” so that he can stay with us next year. Alas, he’s graduating on schedule, with highest honors and a boatload of references to attest to his skill, hard work, and talent. I’m honored to be one of them.

I enthusiastically recommend Daniel for the position of server/manager in your café. If you have any specific questions about Daniel’s experience and skills, I’m happy to help. Please call me at 555-555-5555.

A character reference is a recommendation written by someone who can attest to one’s character. These letters may be needed for people applying to join an association or purchase a property.

They can be used as an alternative to a professional reference for someone who doesn't have work experience, and they may also be required for jobs that require a high level of trustworthiness.

Who to Ask for a Character Reference

If you have limited work experience (or worry you will get a negative reference from your former employer), you might ask someone to write you a character reference. This might help balance out a negative employer reference.

Consider asking a friend, neighbor, club leader, colleague, or someone else who may never have employed you but can speak to who you are as a person.

What to Include in a Character Reference

If you are asked to write a character reference, focus on the person’s character traits and abilities. You can provide examples from personal interactions with that individual.

Sandra Gomez Program Director Kids at Play, Inc. Centertown, New Hampshire 03225

Dear Ms. Gomez,

Before I had the pleasure of working with Liz Dwyer on our neighborhood cleanup committee, I was her next-door neighbor for 10 years. It didn’t surprise me at all when she was the youngest person to show up for our initial organizational meeting or when she volunteered to take notes and spearheaded the playground project. 

Liz is a very special young person, the kind that gives you hope for the future. It’s not just that she’s organized and dependable, although she is. It’s that she has passion, drive, and a deep optimism for what’s possible. I’ve seen firsthand how she uses that optimism to inspire others and help them see the possibilities in an empty lot or rundown corner. 

I’ve also been impressed with Liz’s growth as an artist. Since she started at Eastern College, her talent has grown. She has used her new skills to improve our neighborhood, rallying the local kids to help her make a mosaic wall for the new playground. 

I know she would be a bright light in your arts program, inspiring and guiding the kids in your care just as she has the kids on our block. I enthusiastically recommend her for the job. Please feel free to reach out to me at jane.lee@email.com or (413)555-6078 with any questions. 

Best regards,

Jane Lee Director, Chestnut Street Block Association

A reference list is a page with a list of your references and their contact information. Send this letter as part of your job application if it is requested. Employers who ask for a reference list might call or email the people on that list and ask them for more information about you.

When creating your reference list, be sure to first ask permission from each person on your list. Not only is this polite, but this will give each person time to prepare a response for the employer. Make sure you provide all the necessary contact information for each person.

What should a student’s letter of recommendation include?

A letter of recommendation for a student should describe their positive qualities, including their academic achievements, interpersonal skills, work ethic, and character. To be effective, the letter should focus on skills and qualifications that are most valuable in the job or program for which the student is applying. 

How long should a recommendation letter be?

A recommendation letter should be at least a few paragraphs long, typically a page or two in length. It should contain specifics that illustrate why the subject is a good candidate for the job or position they’re seeking. The recommender should unreservedly endorse the subject of the letter.

How to Write a Letter of Recommendation [With Tips & Template]

Every now and then, applying for a position will require that you also submit a letter of recommendation. 

Or, maybe, a coworker will ask you to write a recommendation letter for their new job application.

If you're not certain how to go about it, don't worry - nothing about recommendation letters needs to be complicated. Especially once you learn the nitty-gritty of the topic. 

This is exactly what this article is here to teach you!

What is a Recommendation Letter?

What should a letter of recommendation include.

• How to Write a Letter of Recommendation

3 Types of Recommendation Letters

• How to Ask For a Recommendation Letter
• Recommendation Letter Template

A letter of recommendation is a formal document confirming and recommending a person’s work, skills, or academic performance and potential. 

Typically, a recommendation letter is required for: 

• University admissions
• Fellowships or internship positions
• Job applications
• Volunteering opportunities

You should ideally write a recommendation for someone whose abilities and work ethic you are familiar with - for example, a colleague, student you taught, your employee, or someone you supervised at work.

Similarly, if you’re the one asking for a recommendation letter, you should ask someone who can attest to your professional or academic abilities. 

The types of recommendation letters are:

• Academic recommendation letters.
• Employment recommendation letters.
• Character recommendation letters.

Here’s what each type of recommendation letter is about:

#1. Academic Recommendation Letters

Academic recommendation letters are typically required to be submitted by students during the admission processes of graduate and undergraduate schools. 

Generally, each prospective student is requested to submit up to three references, which can be written by any education professional familiar with the candidate’s academic background. 

Academic reference letters include:

• Recommendation letter for undergraduate/graduate school
• Recommendation letter for a scholarship
• Recommendation letter for a fellowship program

#2. Employment recommendation letters 

This type makes up the most popular type of recommendation letter.

Sometimes, employers can ask you to submit up to 3 recommendation letters as part of your job application.

More often, though, a recruiter might ask you for recommendation letters if they already like your resume and want to learn more about you. 

Employment recommendation letters are written by former - or current - coworkers, employers, or supervisors.

If you can choose, pick someone with more years of experience than you. After all, the more senior they are, the more weight their recommendation carries.

Employment recommendations include: 

• Recommendation letter for a coworker
• Recommendation letter for a (former) employee

#3. Character recommendation letters

Character recommendation letters, also known as personal references, are used to describe an individual’s personality by someone who knows them well, including close friends, coworkers, or employers. 

Personal references serve many purposes, the primary ones being court cases dealing with criminal issues such as drunk driving offenses, or legal situations such as child adoption procedures. 

It is not uncommon, however, to have a potential landlord or even immigration officials ask for a personal reference. 

Personal references include: 

• Recommendation letter for a friend
• Recommendation letter for a tenant
• Recommendation letter for a patient

Recommendation letters follow a particular format and layout that make writing them significantly easier. 

In this section, we’ll cover how to do each the right way, starting with:

Letter of Recommendation Format

A letter of recommendation includes the following sections: 

• The salutation ; if you are addressing someone whose name you know or writing a personal recommendation letter, the salutation can be addressed to “Dear Mr./Mrs./Dr. Smith.” Otherwise, you may use the generic “to whom it may concern.”
• The introduction , which first and foremost includes your statement of recommendation (i.e. “ it is my pleasure to recommend… ”). It is common to also briefly state who you are and what your expertise is.
• The overview, or a description of the applicant’s top skills, attributes, and strengths.
• A personal story describing more of the applicant’s skills and qualifications.
• The closing statement , or the final call for action, is where you encourage the recruiter to contact you if additional information is needed.
• The signature , where you repeat your name and include your full contact information.

Letter of Recommendation Layout 

When it comes to the layout of the recommendation letter, all you need to do is follow some basic formatting rules. Here are the most important ones: 

#1. One page length. This rule applies to resumes too, but it’s even more essential for the recommendation letter. Recruiters go through hundreds of them, so chances are they appreciate concise, to-the-point letters that don’t waste their time. And besides, a good recommendation letter doesn’t have to be an essay to get the recruiter ‘hooked’ - especially if you follow the above format. 

#2. Single-spaced lining, with space between paragraphs . This also keeps your reference letter within the limit by shortening the text. 

#3. Traditional font. Don’t go for something too creative - pick a classic that works. We recommend Times New Roman, Calibri, Arial, Ubuntu, Roboto or Overpass.

#4. 1” margins on all sides . This creates enough white space around the margins and makes the letter easy to read. Additionally, the text should be aligned to the left - although this is a standard alignment for most documents.    

#5. 10-12pt font size . This is the font size range that makes the document easy to read. Adjusting the font size is another good way to keep your recommendation letter within the length limit.

Recommendation letters usually follow similar layout rules as resumes. Learn more about font size and style from our article on the best resume font, size, and format .

How to Ask for a Recommendation Letter 

Need to ask someone for a recommendation letter? Here’s what you need to know.

The go-to person for your recommendation letter will depend on the type of reference you’ll need. 

For example, if you need an employment recommendation letter , your top choices should involve people who are familiar with your work ethic and professional abilities, but with whom you’ve also had a positive professional relationship. For example:

• Your team lead
• Department head
• CEO of the company
• Direct manager
• A coworker you’ve worked with together on a project

If you are a recent graduate with little work experience, you can ask a mentor or college professor to write you a professional reference. 

In case you need an academic recommendation letter , consider asking a professor with whom you’ve worked closely and can positively attest to your academic potential and achievements.

Your thesis advisor, for example, would make a good choice to ask for an academic reference. If you never wrote a Bachelor’s or Master’s thesis, any professor who knows you as more than just a face in a sea of students should do the trick. 

Finally, keep the following in mind when the time comes to ask for a recommendation letter: 

• Whoever you end up asking, talk to them about it in advance . Then, follow up with a formal email that should contain all reference-related information, such as the submission details and deadline. The email can also include a description of what you’re currently doing (professionally, academically, or independently), what qualifies you for the position, and some relevant skills, achievements, or noteworthy facts.
• If you’re asking for a professional recommendation letter, make sure to also include your resume and the job description in the follow-up email. This way, the person writing the letter will know more about you and your new position and will be able to write a more relevant recommendation by tailoring your skills to the job, or by mentioning some of your (relevant) achievements.
• Notify the contacts you’ll be asking - considering that in most cases recruiters ask for up to three recommendation letters - at least two weeks in advance. This will give them enough time to prepare and write a good recommendation letter. This is especially important for academic references because professors are usually writing several recommendation letters simultaneously.
• Consider attaching a recommendation letter template such as the one provided in this article to your email. The template will considerably ease or guide them through the process of writing the letter.
• Follow up by sending thank you notes to everyone who writes you a recommendation letter. Sending a letter of appreciation is a courtesy act that will let them know you are grateful for the time and effort they took to recommend you positively.

In this section, we’ll teach you how to write a recommendation letter that will impress the recruiter and help your referee!

Tip #1. Write an Attention-Grabbing Introduction  

First things first - the introduction.

This is where you need to grab the reader’s attention and get them interested in reading the recommendation letter. 

How to go about it? Before formally (and briefly) introducing yourself, aim to write an attention-grabbing recommendation statement, instead of a generic one the recruiter probably knows by heart already. 

Let’s explain this more practically: 

Dear Mr. Smith, 

I am pleased to recommend Sarah McKay for the Communications Assistant position.

Nothing wrong with this introduction at first glance, right? It’s a standard way of opening a recommendation letter after all. 

Well that’s exactly what’s wrong with it - it’s way too common. No, this probably won’t get your application disqualified, but it won’t impress the recruiter either.

Want yours to strike the right note? Try something like this instead:

Dear Mr. Smith,

I am sincerely glad to be the one recommending Sarah McKay for the Communications Assistant position.

This recommendation statement is not significantly different from the previous one, except for one thing: it gives the reference letter a head start by implying that recommending Sarah is an honor. And that’s more likely to get the recruiter’s attention - or, at least, curiosity. 

In case you’re struggling to come up with an attention-grabbing introduction, simply mention one of the following points, and you’re good to go: 

• A little-known fact about the candidate. 
• Your general consideration of the candidate’s qualities.
• A remarkable achievement or award the candidate might have won.  

Tip #2. Establish a Meaningful Relationship With the Candidate 

All recommendation letters explain what the relationship with the referee is before listing their skills and qualifications. 

To make the recommendation more meaningful, you should show the recruiter you are just the right person to attest to the candidate’s abilities. And that’s not something you can convey by simply stating how you know them. Take the following example:   

I have taught Jake Political Science for four years. 

Does this example tell the recruiter how you know the applicant? Sure, it does. 

But it does so in a boring way and without establishing a convincing relationship with them. For all the recruiter knows, Jake is just one out of a thousand students you’ve taught over the years.

It has been a pleasure for me to teach Jake for four years and guide him through his remarkable Bachelor’s thesis in Conflict Resolution.

Notice the difference? This example specifies the writer is Jake’s thesis advisor, which makes the recommendation all the more meaningful. 

Tip #3. Tailor Your Recommendation to the Application 

Want to put in the extra effort and make sure your referee truly stands out?

Tailor the recommendation letter to the job / university program they’re applying for.

Tailoring your letter to the candidate’s application is easiest when you’re recommending someone for employment (you can just check the job requirements), but it works for any type of recommendation (incl. academic). All you need to do is match the referee’s skills and strengths to whatever they’re applying for. 

Let’s assume, for example, that you’re recommending a co-worker for a marketing manager position.

Some of the job requirements are: 

• +5 years of professional experience in marketing
• Experience developing marketing campaigns 
• Excellent communication skills 
• Project-management and multi-tasking skills 

To tailor your recommendation to the job requirements, all you need to do is mention them as your referee’s best qualities. For example: 

Even after seven years working together, Ema’s skillful way of effectively communicating with clients and co-workers alike doesn’t cease to amaze me. It only comes second to her multi-tasking abilities, which I’ve witnessed throughout the many marketing campaigns we have developed and managed. 

As you can see, there’s not much to it. 

All you need to do is check the job requirements, pick several skills and qualifications, and make them part of your referee’s top skills, strengths, or personality traits.  

Tip #4. List the Candidate’s Achievements 

Mentioning some of the candidate’s achievements is another great way to help your referee really stand out.

After all, skills, strengths, and character traits are awesome, but they can also come across as meaningless if you can’t back them up with facts. 

What do we mean by this?

Let us explain:

Here’s how a typical personal story in a recommendation letter looks like:

I came to truly appreciate Eric’s work ethic, passion, and attention to detail the first time I assigned him to do a report on child trafficking. Eric was respectful of journalistic ethics but also willing to chase the story relentlessly, believing in its value and importance. 

Sure, this is a perfectly acceptable personal story. 

However, it doesn’t do much more than just list the referee’s skills, traits, and work experience through a subjective lens. 

What we’re saying is, it doesn’t really sell the candidate.

Now, let’s compare it to the following:

Eric’s ability to chase after difficult stories first became apparent when I assigned him a report about child trafficking. Despite the challenging topic, Eric not only pulled through but achieved more than expected by a) identifying a trafficking ring that put more than 50 minors into forced begging, b) interviewing 10 of the older minors and managing to bring that trafficking network down once the reportage went public and c) increasing the TV Channel’s ratings by 40% in 3 weeks. 

By mentioning those achievements, your account of the candidate’s experiences is a lot more “factual,” as well as impressive for the recruiter.

Tip #5. Polish Up Your Recommendation Letter

Finally, here’s 5 more simple tips to get your recommendation letter ready:

• Maintain positive rhetoric . At no point throughout your reference letter should the recruiter sense a hint of doubt regarding the applicant’s skills and qualifications.
• Don’t overdo the positivity. Extremes are never good - which means being overly positive might also come across as a bit suspicious or weird (even if everything you're saying is true). 
• Follow the submission instructions . A bunch of employers, but also educational institutions, will provide instructions on how to submit the recommendation letter. We recommend you ask the candidate to double-check them and give you a heads up, because if you submit the recommendation letter wrong, the candidate might lose their chance.
• Use a business tone . Even when you’re being creative, your writing tone should maintain a business tone - polite, and as formal as possible.
• Mind your grammar and spelling . This is another tip that goes for all things application-related. You won’t compromise the referee’s chances with a typo, but your recommendation won’t matter much either if it’s filled with simple grammar/spelling mistakes. Run your letter through a grammar and spell-check app once you’re finished with it, just to be on the safe side of things.

Recommendation Letter FAQ

Still have some questions on how to write a letter of recommendation?

Find your answers below!

1. What is a professional letter of recommendation?

A professional letter of recommendation - also called an employment recommendation letter - refers to an official document that is typically required when you apply for a job and which describes the applicant’s professional skills, experiences, and qualifications. 

Professional letters of recommendation are typically written by current or previous employers or supervisors. A coworker can also write you a professional letter of recommendation, but it’s not as optimal as a coworker is not really an authority figure (and might just be a friend doing you a favor instead of being honest).

2. What should be written in a letter of recommendation?

Letters of recommendation generally follow the following format: 

• A formal salutation
• An introduction (which includes a recommendation statement and your professional title)
• An overview of some of the applicant’s skills, strengths, or qualifications, which you can tailor to the application
• A personal story where you can mention some of the applicant’s achievements
• A closing statement and call for action
• A signature , with your contact information

3. Who should I ask for a letter of recommendation?

If you’re asking for an academic letter of recommendation, you can ask:

• Current or former professors
• Academic mentors
• Thesis advisors

If you’re asking for a professional recommendation letter, though, you can ask:

• Current or former employers
• A supervisor or professional mentor
• Former professors
• Experienced coworkers

4. How do you start a recommendation paragraph?

To keep the recruiter reading your recommendation letter interested, you should start with an attention-grabbing introduction - specifically, an interesting recommendation statement. 

This statement is the opening sentence of the letter and it should optimally express your conviction to recommend the applicant in a non-generic way. 

If you’re struggling with coming up with something creative, just start with one of the following:

• A little-known or impressive fact about the candidate
• Your general consideration of the candidate’s qualities
• A remarkable achievement, or an award the candidate might have won

5. How do you end a letter of recommendation?

A letter of recommendation concludes with a call to action or a request towards the recruiter   showing your availability and willingness to provide additional information if needed. After mentioning that you remain available to discuss the candidate’s qualifications, you may finalize the letter with your signature - your name, title, and company.

Key Takeaways 

And that’s a wrap! We hope this article will make the process of writing a recommendation letter easier for you. 

Let’s go over some of the main points we covered: 

• A letter of recommendation is a formal letter confirming and recommending a person’s work, skills, or academic performance and potential.
• Recommendation letters follow a particular format and layout. The format typically consists of 1) the letterhead and full contact information, 2) a salutation, 3) an introduction, 4) an overview, 5) a personal story, 6) a closing sentence and 7) your signature.
• The three types of recommendation letters are employment, academic, and character recommendation letters.
• Who to ask for a recommendation letter depends on the type of reference you need. As a rule of thumb, pick someone who knows your skills and strengths well and whom you’ve had a positive experience (professional or academic) with.

Letters of Recommendation

Anyone who's applied for a job knows how important recommendation letters can be to getting hired. While you've probably asked for a reference letter in the past, you may be less familiar with writing one. If someone asks you for a reference, how can you produce a great letter that will help your employee, colleague, or friend get hired?

To help you through the writing process, we're providing nine samples of effective letters of recommendation (scroll down to skip to the samples!). By reading through these examples, you'll gain a clear understanding of how to structure your own letters.

Before getting to the free recommendation letter samples, let's briefly review the role that reference letters play in the hiring process. Why are they important, and what makes some stand out over others?

Why Are Recommendation Letters Important?

Many employers request recommendation letters to help them decide who to hire or internally promote. Throughout the hiring process, the applicant strives to present herself in the best light. Beyond the interview and resume, hiring managers look to recommendation letters to confirm the candidate's qualifications and to gain insight from an outside party.

The hiring manager wants to know what experiences the candidate will bring to the new role, how she'll contribute to the company or organization, and how she'll behave in the day-to-day. Recommendation letters can point to a candidate's future performance by talking about her past achievements.

Reference letters can also shed light on what it's like to manage, work with, or, in the case of a character reference, be friends with the person under consideration. They complement the candidate's story and suggest what she'll bring to the table in her next job.

If you get asked to write a letter for someone, it's safe to assume you want to do a good job. Helping someone get hired is not just a satisfying good deed, but it's also good professional karma! So how can you turn those good intentions into a stand-out employee letter of recommendation?

Each letter will, of course, be different, but good letters share certain key features. Read on to learn about three important characteristics of strong reference letters.

Your recommendation letter's not the time to be cagey about your identity! The hiring manager wants to know who you are and why you're qualified to recommend the applicant.

What Makes a Recommendation Letter Stand Out? 3 Key Features

Strong letters give positive descriptions of a candidate's skills in a concise and powerful way. Beyond using language that's clear and error-free, what elements should your recommendation letter include to be effective?

As you write your letter, make sure it does the following:

#1: Explains Why You're Qualified to Recommend the Candidate

In order to hold weight, a recommendation letter should come from a reputable source. If an employer wants a professional reference, then the writer of that letter probably worked with the candidate in a supervisory capacity. Some employers will also be interested in letters from a colleague or, occasionally, a friend, neighbor, or family member. Most letters, though, will be written by a supervisor, manager, or boss of some sort.

In the first paragraph, you should explain who you are and how you know the candidate. How long did you work with her and in what capacity? By explaining your relationship, you show that you're qualified to give an honest assessment.

If someone who feels like a relative stranger asks you to write a letter, you might consider declining or recommending someone else to write it. If you didn't get to know the candidate's work performance or only did so in a way completely unrelated to the new position, then you might not be able to provide a helpful letter of recommendation from employer to employee.

The best letters are written by people who can speak to the candidate's skills and accomplishments. Make sure to state clearly in the beginning of your letter who you are and why your opinion matters.

#2: Customized to the New Position

While you should speak to the candidate's accomplishments in her past role, you should also show why she'd make a good fit in the next one. Even if the candidate's making a career change, you can explain why she'll be able to do well in the new industry.

Here's where open communication with the applicant is important. She should share the job description so you have a clear understanding of the position's requirements. As the writer, you're not expected to do much research on the new job. The candidate should provide you with everything you need to know to customize your letter.

By drawing on this information, you can express confidence that the candidate will succeed in the new role. Then when the hiring manager reads your letter, she'll feel reassured that the candidate would make a good fit.

#3: Uses Specific Examples and Anecdotes

Finally, and perhaps most importantly, your letter should provide specific examples about the candidate. Don't just list adjectives like, "friendly, intelligent, and hard-working"; instead, present circumstances in which the candidate demonstrated those qualities. To borrow a favorite phrase of English teachers, "show, don't just tell."

Not only will examples point to the value the candidate brought to your organization or company, but they'll also paint a picture of how she works in day-to-day operations. Using two to three specific anecdotes in your letter will boost its level of persuasiveness. It will also sidestep a common rec letter trap: becoming a generic list of cliches.

Just as you should only write a recommendation letter if you feel qualified to assess the candidate, you should also only write it if you can provide a great one. While you don't want to go over the top and sound insincere, your letter should be a strongly positive endorsement.

Sample Recommendation Letters

As you read through the nine free job recommendation letters below, notice how they all share the three key features described above, even though they differ in terms of their source and target audience. Below are nine sample recommendation letters, each followed by an analysis of what it does well!

• Sample Recommendation Letter 1: Written by a Direct Manager for a Full-Time Employee
• Sample Recommendation Letter 2: Written by a Principal for a Teacher
• Sample Recommendation Letter 3: Written by a Direct Manager for a Part-Time Employee
• Sample Recommendation Letter 4: Written by a Manager for a Remote Worker
• Sample Recommendation Letter 5: Written by a Supervisor for an Internal Promotion
• Sample Recommendation Letter 6: Written by a Supervisor for a Student Intern
• Sample Recommendation Letter 7: Written by a Coworker
• Sample Recommendation Letter 8: Written by a Professor for a Former Student
• Sample Recommendation Letter 9: Written by a Friend as a Character Reference

After checking out the above samples of recommendation letters, read on for some final thoughts on how to write an excellent letter of recommendation for an employee, coworker, or friend.

Now that you've got all the building blocks, you can put them together into a powerful letter of recommendation!

Writing Strong Letters of Recommendation: Final Thoughts

While the above samples of recommendation letters will help guide you through the letter writing process, they can't look exactly like your final product. Writing a letter is a significant undertaking, as it requires you to customize your words to the candidate and make your letter unique. Even though the specifics will vary, strong letters of recommendation do have certain features in common. Each letter should...

Use an Official Format

The sample letters show the proper format for a recommendation letter. They have the employer's name, position, company, and company's address at the top. To give one example, here's the header for recommendation letter sample #1:

Ms. Greta Johanssen Sales Manager Streambase Corp. 66 Western Boulevard Santa Fe, New Mexico 87500

You should also use official letterhead that has your name and contact information across the top, in whatever way you've chosen to present it. Each letter is addressed to a specific person, a greeting that's more personal than, "Dear Hiring Manager." Typically, paragraphs are single-spaced with a double space in between each one.

Finally, every letter concludes with an invitation to contact the writer for any further information. Then the writer may include her position, company, phone number, and email below her name.

Start with a Strong Opener

The strongest letters start out with an immediate statement of support. They might say, "It's my honor," "It's my pleasure," or "I'm very pleased to provide this letter of recommendation for Joe." Stating the obvious with a sentence like, "I'm writing to recommend Joe," looks weak beside a more enthusiastic opener.

In the first paragraph, explain who you are and why you're qualified to recommend the candidate. Write a line or two of praise about her professional and personal strengths, perhaps with a summary of the main points you'll present in the rest of the letter.

Include Two to Three Specific Examples

As mentioned above, strong letters typically include two to three body paragraphs with specific anecdotes about the candidate. They don't just describe the applicant's great qualities and accomplishments; they give examples and prove to her prospective employer that she's made achievements in the past that predict future success.

You might talk about a project or responsibility of the applicant or the value she's brought to your company. Consider relevant qualities like flexibility, initiative, leadership, growth, collaboration, interpersonal skills, and/or ability to perform within a certain environment or culture.

To Sum Up...

Depending on your relationship with the candidate, you might focus more on her work performance or personal character in your recommendation letter. An employer will focus more heavily on professional skills while a coworker may add personal qualities.

A friend or neighbor providing a character reference would produce the most personal letter. It falls upon the candidate to choose her recommenders wisely and to share any relevant information about the prospective position to help them write the best letter they can.

As long as you incorporate the key features discussed above and take the time to make your letter positive and specific, you'll provide a strong recommendation letter that will help your employee, colleague, or friend get hired. And who knows—perhaps in a year or two, she'll be writing a recommendation letter for you!

Today, we’re excited to share the first two models of the next generation of Llama, Meta Llama 3, available for broad use. This release features pretrained and instruction-fine-tuned language models with 8B and 70B parameters that can support a broad range of use cases. This next generation of Llama demonstrates state-of-the-art performance on a wide range of industry benchmarks and offers new capabilities, including improved reasoning. We believe these are the best open source models of their class, period. In support of our longstanding open approach, we’re putting Llama 3 in the hands of the community. We want to kickstart the next wave of innovation in AI across the stack—from applications to developer tools to evals to inference optimizations and more. We can’t wait to see what you build and look forward to your feedback.

Our goals for Llama 3

With Llama 3, we set out to build the best open models that are on par with the best proprietary models available today. We wanted to address developer feedback to increase the overall helpfulness of Llama 3 and are doing so while continuing to play a leading role on responsible use and deployment of LLMs. We are embracing the open source ethos of releasing early and often to enable the community to get access to these models while they are still in development. The text-based models we are releasing today are the first in the Llama 3 collection of models. Our goal in the near future is to make Llama 3 multilingual and multimodal, have longer context, and continue to improve overall performance across core LLM capabilities such as reasoning and coding.

State-of-the-art performance

Our new 8B and 70B parameter Llama 3 models are a major leap over Llama 2 and establish a new state-of-the-art for LLM models at those scales. Thanks to improvements in pretraining and post-training, our pretrained and instruction-fine-tuned models are the best models existing today at the 8B and 70B parameter scale. Improvements in our post-training procedures substantially reduced false refusal rates, improved alignment, and increased diversity in model responses. We also saw greatly improved capabilities like reasoning, code generation, and instruction following making Llama 3 more steerable.

*Please see evaluation details for setting and parameters with which these evaluations are calculated.

In the development of Llama 3, we looked at model performance on standard benchmarks and also sought to optimize for performance for real-world scenarios. To this end, we developed a new high-quality human evaluation set. This evaluation set contains 1,800 prompts that cover 12 key use cases: asking for advice, brainstorming, classification, closed question answering, coding, creative writing, extraction, inhabiting a character/persona, open question answering, reasoning, rewriting, and summarization. To prevent accidental overfitting of our models on this evaluation set, even our own modeling teams do not have access to it. The chart below shows aggregated results of our human evaluations across of these categories and prompts against Claude Sonnet, Mistral Medium, and GPT-3.5.

Preference rankings by human annotators based on this evaluation set highlight the strong performance of our 70B instruction-following model compared to competing models of comparable size in real-world scenarios.

Our pretrained model also establishes a new state-of-the-art for LLM models at those scales.

To develop a great language model, we believe it’s important to innovate, scale, and optimize for simplicity. We adopted this design philosophy throughout the Llama 3 project with a focus on four key ingredients: the model architecture, the pretraining data, scaling up pretraining, and instruction fine-tuning.

Model architecture

In line with our design philosophy, we opted for a relatively standard decoder-only transformer architecture in Llama 3. Compared to Llama 2, we made several key improvements. Llama 3 uses a tokenizer with a vocabulary of 128K tokens that encodes language much more efficiently, which leads to substantially improved model performance. To improve the inference efficiency of Llama 3 models, we’ve adopted grouped query attention (GQA) across both the 8B and 70B sizes. We trained the models on sequences of 8,192 tokens, using a mask to ensure self-attention does not cross document boundaries.

Training data

To train the best language model, the curation of a large, high-quality training dataset is paramount. In line with our design principles, we invested heavily in pretraining data. Llama 3 is pretrained on over 15T tokens that were all collected from publicly available sources. Our training dataset is seven times larger than that used for Llama 2, and it includes four times more code. To prepare for upcoming multilingual use cases, over 5% of the Llama 3 pretraining dataset consists of high-quality non-English data that covers over 30 languages. However, we do not expect the same level of performance in these languages as in English.

To ensure Llama 3 is trained on data of the highest quality, we developed a series of data-filtering pipelines. These pipelines include using heuristic filters, NSFW filters, semantic deduplication approaches, and text classifiers to predict data quality. We found that previous generations of Llama are surprisingly good at identifying high-quality data, hence we used Llama 2 to generate the training data for the text-quality classifiers that are powering Llama 3.

We also performed extensive experiments to evaluate the best ways of mixing data from different sources in our final pretraining dataset. These experiments enabled us to select a data mix that ensures that Llama 3 performs well across use cases including trivia questions, STEM, coding, historical knowledge, etc.

Scaling up pretraining

To effectively leverage our pretraining data in Llama 3 models, we put substantial effort into scaling up pretraining. Specifically, we have developed a series of detailed scaling laws for downstream benchmark evaluations. These scaling laws enable us to select an optimal data mix and to make informed decisions on how to best use our training compute. Importantly, scaling laws allow us to predict the performance of our largest models on key tasks (for example, code generation as evaluated on the HumanEval benchmark—see above) before we actually train the models. This helps us ensure strong performance of our final models across a variety of use cases and capabilities.

We made several new observations on scaling behavior during the development of Llama 3. For example, while the Chinchilla-optimal amount of training compute for an 8B parameter model corresponds to ~200B tokens, we found that model performance continues to improve even after the model is trained on two orders of magnitude more data. Both our 8B and 70B parameter models continued to improve log-linearly after we trained them on up to 15T tokens. Larger models can match the performance of these smaller models with less training compute, but smaller models are generally preferred because they are much more efficient during inference.

To train our largest Llama 3 models, we combined three types of parallelization: data parallelization, model parallelization, and pipeline parallelization. Our most efficient implementation achieves a compute utilization of over 400 TFLOPS per GPU when trained on 16K GPUs simultaneously. We performed training runs on two custom-built 24K GPU clusters . To maximize GPU uptime, we developed an advanced new training stack that automates error detection, handling, and maintenance. We also greatly improved our hardware reliability and detection mechanisms for silent data corruption, and we developed new scalable storage systems that reduce overheads of checkpointing and rollback. Those improvements resulted in an overall effective training time of more than 95%. Combined, these improvements increased the efficiency of Llama 3 training by ~three times compared to Llama 2.

Instruction fine-tuning

To fully unlock the potential of our pretrained models in chat use cases, we innovated on our approach to instruction-tuning as well. Our approach to post-training is a combination of supervised fine-tuning (SFT), rejection sampling, proximal policy optimization (PPO), and direct preference optimization (DPO). The quality of the prompts that are used in SFT and the preference rankings that are used in PPO and DPO has an outsized influence on the performance of aligned models. Some of our biggest improvements in model quality came from carefully curating this data and performing multiple rounds of quality assurance on annotations provided by human annotators.

Learning from preference rankings via PPO and DPO also greatly improved the performance of Llama 3 on reasoning and coding tasks. We found that if you ask a model a reasoning question that it struggles to answer, the model will sometimes produce the right reasoning trace: The model knows how to produce the right answer, but it does not know how to select it. Training on preference rankings enables the model to learn how to select it.

Building with Llama 3

Our vision is to enable developers to customize Llama 3 to support relevant use cases and to make it easier to adopt best practices and improve the open ecosystem. With this release, we’re providing new trust and safety tools including updated components with both Llama Guard 2 and Cybersec Eval 2, and the introduction of Code Shield—an inference time guardrail for filtering insecure code produced by LLMs.

We’ve also co-developed Llama 3 with torchtune , the new PyTorch-native library for easily authoring, fine-tuning, and experimenting with LLMs. torchtune provides memory efficient and hackable training recipes written entirely in PyTorch. The library is integrated with popular platforms such as Hugging Face, Weights & Biases, and EleutherAI and even supports Executorch for enabling efficient inference to be run on a wide variety of mobile and edge devices. For everything from prompt engineering to using Llama 3 with LangChain we have a comprehensive getting started guide and takes you from downloading Llama 3 all the way to deployment at scale within your generative AI application.

A system-level approach to responsibility

We have designed Llama 3 models to be maximally helpful while ensuring an industry leading approach to responsibly deploying them. To achieve this, we have adopted a new, system-level approach to the responsible development and deployment of Llama. We envision Llama models as part of a broader system that puts the developer in the driver’s seat. Llama models will serve as a foundational piece of a system that developers design with their unique end goals in mind.

Instruction fine-tuning also plays a major role in ensuring the safety of our models. Our instruction-fine-tuned models have been red-teamed (tested) for safety through internal and external efforts. ​​Our red teaming approach leverages human experts and automation methods to generate adversarial prompts that try to elicit problematic responses. For instance, we apply comprehensive testing to assess risks of misuse related to Chemical, Biological, Cyber Security, and other risk areas. All of these efforts are iterative and used to inform safety fine-tuning of the models being released. You can read more about our efforts in the model card .

Llama Guard models are meant to be a foundation for prompt and response safety and can easily be fine-tuned to create a new taxonomy depending on application needs. As a starting point, the new Llama Guard 2 uses the recently announced MLCommons taxonomy, in an effort to support the emergence of industry standards in this important area. Additionally, CyberSecEval 2 expands on its predecessor by adding measures of an LLM’s propensity to allow for abuse of its code interpreter, offensive cybersecurity capabilities, and susceptibility to prompt injection attacks (learn more in our technical paper ). Finally, we’re introducing Code Shield which adds support for inference-time filtering of insecure code produced by LLMs. This offers mitigation of risks around insecure code suggestions, code interpreter abuse prevention, and secure command execution.

With the speed at which the generative AI space is moving, we believe an open approach is an important way to bring the ecosystem together and mitigate these potential harms. As part of that, we’re updating our Responsible Use Guide (RUG) that provides a comprehensive guide to responsible development with LLMs. As we outlined in the RUG, we recommend that all inputs and outputs be checked and filtered in accordance with content guidelines appropriate to the application. Additionally, many cloud service providers offer content moderation APIs and other tools for responsible deployment, and we encourage developers to also consider using these options.

Deploying Llama 3 at scale

Llama 3 will soon be available on all major platforms including cloud providers, model API providers, and much more. Llama 3 will be everywhere .

Our benchmarks show the tokenizer offers improved token efficiency, yielding up to 15% fewer tokens compared to Llama 2. Also, Group Query Attention (GQA) now has been added to Llama 3 8B as well. As a result, we observed that despite the model having 1B more parameters compared to Llama 2 7B, the improved tokenizer efficiency and GQA contribute to maintaining the inference efficiency on par with Llama 2 7B.

For examples of how to leverage all of these capabilities, check out Llama Recipes which contains all of our open source code that can be leveraged for everything from fine-tuning to deployment to model evaluation.

What’s next for Llama 3?

The Llama 3 8B and 70B models mark the beginning of what we plan to release for Llama 3. And there’s a lot more to come.

Our largest models are over 400B parameters and, while these models are still training, our team is excited about how they’re trending. Over the coming months, we’ll release multiple models with new capabilities including multimodality, the ability to converse in multiple languages, a much longer context window, and stronger overall capabilities. We will also publish a detailed research paper once we are done training Llama 3.

To give you a sneak preview for where these models are today as they continue training, we thought we could share some snapshots of how our largest LLM model is trending. Please note that this data is based on an early checkpoint of Llama 3 that is still training and these capabilities are not supported as part of the models released today.

We’re committed to the continued growth and development of an open AI ecosystem for releasing our models responsibly. We have long believed that openness leads to better, safer products, faster innovation, and a healthier overall market. This is good for Meta, and it is good for society. We’re taking a community-first approach with Llama 3, and starting today, these models are available on the leading cloud, hosting, and hardware platforms with many more to come.
