Homework: A New User's Guide
Cory Turner
If you made it past the headline, you're likely a student, concerned parent, teacher or, like me, a nerd nostalgist who enjoys basking in the distant glow of Homework Triumphs Past (second-grade report on Custer's Last Stand, nailed it!).
Whoever you are, you're surely hoping for some clarity in the loud, perennial debate over whether U.S. students are justifiably exhausted and nervous from too much homework — even though some international comparisons suggest they're sitting comfortably at the average.
Well, here goes. I've mapped out six, research-based polestars that should help guide you to some reasonable conclusions about homework.
How much homework do U.S. students get?
The best answer comes from something called the National Assessment of Educational Progress or NAEP . In 2012, students in three different age groups — 9, 13 and 17 — were asked, "How much time did you spend on homework yesterday?" The vast majority of 9-year-olds (79 percent) and 13-year-olds (65 percent) and still a majority of 17-year-olds (53 percent) all reported doing an hour or less of homework the day before.
Another study from the National Center for Education Statistics found that high school students who reported doing homework outside of school did, on average, about seven hours a week.
If you're hungry for more data on this — and some perspective — check out this exhaustive report put together last year by researcher Tom Loveless at the Brookings Institution.
An hour or less a day? But we hear so many horror stories! Why?
The fact is, some students do have a ton of homework. In high school we see a kind of student divergence — between those who choose or find themselves tracked into less-rigorous coursework and those who enroll in honors classes or multiple Advanced Placement courses. And the latter students are getting a lot of homework. In that 2012 NAEP survey, 13 percent of 17-year-olds reported doing more than two hours of homework the previous night. That's not a lot of students, but they're clearly doing a lot of work.

That also tracks with a famous survey from 2007 — from MetLife — that asked parents what they think of their kids' homework load. Sixty percent said it was just right. Twenty-five percent said their kids are getting too little. Just 15 percent of parents said their kids have too much homework.
Research also suggests that the students doing the most work have something else in common: income. "I think that the debate over homework in some ways is a social class issue," says Janine Bempechat, professor of human development at Wheelock College. "There's no question that in affluent communities, children are really over-taxed, over-burdened with homework."
But the vast majority of students do not seem to have inordinate workloads. And the ones who do are generally volunteering for the tough stuff. That doesn't make it easier, but it does make it a choice.
Do we know how much homework students in other countries are doing?
Sort of. Caveats abound here. Education systems and perceptions of what is and isn't homework can vary remarkably overseas. So any comparison is, to a degree, apples-to-oranges (or, at least, apples-to-pears). A 2012 report from the Organisation for Economic Co-Operation and Development pegged the U.S. homework load for 15-year-olds at around six hours per week. That's just above the study's average. It found that students in Hong Kong are also doing about six hours a week. Much of Europe checks in between four and five hours a week. In Japan, it's four hours. And Korea's near the bottom, at three hours.

How much homework is too much?
Better yet, how much is just right? Harris Cooper at Duke University has done some of the best work on homework. He and his team reviewed dozens of studies, from 1987 to 2003, looking for consensus on what works and what doesn't. A common rule of thumb, he says, is what's called the 10-minute rule. Take the child's grade and multiply by 10. So first-graders should have roughly 10 minutes of homework a night, 40 minutes for fourth-graders, on up to two hours for seniors in high school. A lot of of schools use this. Even the National PTA officially endorses it.
Homework clearly improves student performance, right?
Not necessarily. It depends on the age of the child. Looking over the research, there's little to no evidence that homework improves student achievement in elementary school. Then again, the many experts I spoke with all said the same thing: The point of homework in those primary grades isn't entirely academic. It's about teaching things like time-management and self-direction.
But, by high school the evidence shifts. Harris Cooper's massive review found, in middle and high school, a positive correlation between homework and student achievement on unit tests. It seems to help. But more is not always better. Cooper points out that, depending on the subject and the age of the student, there is a law of diminishing returns. Again, he recommends the 10-minute rule.
What kinds of homework seem to be most effective?
This is where things get really interesting. Because homework should be about learning, right? To understand what kinds of homework best help kids learn, we really need to talk about memory and the brain.
Let's start with something called the spacing effect . Say a child has to do a vocabulary worksheet. The next week, it's a new worksheet with different words and so on. Well, research shows that the brain is better at remembering when we repeat with consistency, not when we study in long, isolated chunks of time. Do a little bit of vocabulary each night, repeating the same words night after night.
Similarly, a professor of psychology at Washington University in St. Louis, Henry "Roddy" Roediger III , recommends that teachers give students plenty of little quizzes, which he says strengthen the brain's ability to remember. Don't fret. They can be low-stakes or no-stakes, says Roediger: It's the steady recall and repetition that matter. He also recommends, as homework, that students try testing themselves instead of simply re-reading the text or class notes.
There's also something known as interleaving . This is big in the debate over math homework. Many of us — myself included — learned math by focusing on one concept at a time, doing a worksheet to practice that concept, then moving on.
Well, there's evidence that students learn more when homework requires them to choose among multiple strategies — new and old — when solving problems. In other words, kids learn when they have to draw not just from what they learned in class that day but that week, that month, that year.
One last note: Experts agree that homework should generally be about reinforcing what students learned in class (this is especially true in math). Sometimes it can — and should — be used to introduce new material, but here's where so many horror stories begin.
Tom Loveless, a former teacher, offers this advice: "I don't think teachers should ever send brand-new material that puts the parent in the position of a teacher. That's a disaster. My own personal philosophy was: Homework is best if it's material that requires more practice but they've already received initial instruction."
Or, in the words of the National PTA: "Homework that cannot be done without help is not good homework."
How Much Homework Is Enough? Depends Who You Ask

Editor’s note: This is an adapted excerpt from You, Your Child, and School: Navigate Your Way to the Best Education ( Viking)—the latest book by author and speaker Sir Ken Robinson (co-authored with Lou Aronica), published in March. For years, Robinson has been known for his radical work on rekindling creativity and passion in schools, including three bestselling books (also with Aronica) on the topic. His TED Talk “Do Schools Kill Creativity?” holds the record for the most-viewed TED talk of all time, with more than 50 million views. While Robinson’s latest book is geared toward parents, it also offers educators a window into the kinds of education concerns parents have for their children, including on the quality and quantity of homework.
The amount of homework young people are given varies a lot from school to school and from grade to grade. In some schools and grades, children have no homework at all. In others, they may have 18 hours or more of homework every week. In the United States, the accepted guideline, which is supported by both the National Education Association and the National Parent Teacher Association, is the 10-minute rule: Children should have no more than 10 minutes of homework each day for each grade reached. In 1st grade, children should have 10 minutes of daily homework; in 2nd grade, 20 minutes; and so on to the 12th grade, when on average they should have 120 minutes of homework each day, which is about 10 hours a week. It doesn’t always work out that way.
In 2013, the University of Phoenix College of Education commissioned a survey of how much homework teachers typically give their students. From kindergarten to 5th grade, it was just under three hours per week; from 6th to 8th grade, it was 3.2 hours; and from 9th to 12th grade, it was 3.5 hours.
There are two points to note. First, these are the amounts given by individual teachers. To estimate the total time children are expected to spend on homework, you need to multiply these hours by the number of teachers they work with. High school students who work with five teachers in different curriculum areas may find themselves with 17.5 hours or more of homework a week, which is the equivalent of a part-time job. The other factor is that these are teachers’ estimates of the time that homework should take. The time that individual children spend on it will be more or less than that, according to their abilities and interests. One child may casually dash off a piece of homework in half the time that another will spend laboring through in a cold sweat.
Do students have more homework these days than previous generations? Given all the variables, it’s difficult to say. Some studies suggest they do. In 2007, a study from the National Center for Education Statistics found that, on average, high school students spent around seven hours a week on homework. A similar study in 1994 put the average at less than five hours a week. Mind you, I [Robinson] was in high school in England in the 1960s and spent a lot more time than that—though maybe that was to do with my own ability. One way of judging this is to look at how much homework your own children are given and compare it to what you had at the same age.
Many parents find it difficult to help their children with subjects they’ve not studied themselves for a long time, if at all.
There’s also much debate about the value of homework. Supporters argue that it benefits children, teachers, and parents in several ways:
- Children learn to deepen their understanding of specific content, to cover content at their own pace, to become more independent learners, to develop problem-solving and time-management skills, and to relate what they learn in school to outside activities.
- Teachers can see how well their students understand the lessons; evaluate students’ individual progress, strengths, and weaknesses; and cover more content in class.
- Parents can engage practically in their children’s education, see firsthand what their children are being taught in school, and understand more clearly how they’re getting on—what they find easy and what they struggle with in school.

Q&A With Sir Ken Robinson
Ashley Norris is assistant dean at the University of Phoenix College of Education. Commenting on her university’s survey, she says, “Homework helps build confidence, responsibility, and problem-solving skills that can set students up for success in high school, college, and in the workplace.”
That may be so, but many parents find it difficult to help their children with subjects they’ve not studied themselves for a long time, if at all. Families have busy lives, and it can be hard for parents to find time to help with homework alongside everything else they have to cope with. Norris is convinced it’s worth the effort, especially, she says, because in many schools, the nature of homework is changing. One influence is the growing popularity of the so-called flipped classroom.
In the stereotypical classroom, the teacher spends time in class presenting material to the students. Their homework consists of assignments based on that material. In the flipped classroom, the teacher provides the students with presentational materials—videos, slides, lecture notes—which the students review at home and then bring questions and ideas to school where they work on them collaboratively with the teacher and other students. As Norris notes, in this approach, homework extends the boundaries of the classroom and reframes how time in school can be used more productively, allowing students to “collaborate on learning, learn from each other, maybe critique [each other’s work], and share those experiences.”
Even so, many parents and educators are increasingly concerned that homework, in whatever form it takes, is a bridge too far in the pressured lives of children and their families. It takes away from essential time for their children to relax and unwind after school, to play, to be young, and to be together as a family. On top of that, the benefits of homework are often asserted, but they’re not consistent, and they’re certainly not guaranteed.
