what's the right amount of homework

How Much Homework Is Enough? Depends Who You Ask

• Share article

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.

The truth about homework in America

by: Carol Lloyd | Updated: May 6, 2024

Print article

Not excited about homework? We can hardly blame you. But how families handle homework in America can have a huge impact on their child’s short-term and long-term academic success. Here’s a glimpse at how American families approach homework, and some tips that may help you decide how to handle homework in your home.

Model how much you value your child’s education

Think of your child’s nightly homework as a time to model how much you value your child’s learning and education. Get in the habit of asking your child what homework they have each evening, looking over their homework when they’re done each night, praising their hard work, and marveling at all that they are learning. Your admiration and love is the best magic learning potion available.

Set up a homework routine American parents who want their children to graduate from high school and go to college take learning at home seriously. They turn off the TV and radio at homework time. They take away access to video games and smartphones. They make sure the child gets some exercise and has a healthy snack before starting homework because both are shown to help kids focus. When it’s time for homework, they (try to) ensure their child has a quiet place where they can focus and have access to the grade-appropriate homework basics, like paper, pencils, erasers, crayons, and tape for kids in younger grades and calculators and writing materials for kids in older grades.

Helping with homework when you don’t read/speak English

So how can you help with homework if you can’t read your child’s homework because it’s in English — or because the math is being presented in a way you’ve never seen? If you can’t understand your child’s homework, you can still do a lot to help them. Your physical presence (and your authority to turn off the TV) can help them take homework time seriously. Your encouragement that they take their time and not rush through the work also will help. Finally, your ability to ask questions can do two important things: you can show your interest in their work (and thus reinforce the importance you place on learning and education) and you can help your child slow down and figure things out when they’re lost or frustrated. A lot of learning happens when children have a chance to talk through problems and ideas. Sometimes, just describing the assignment or problem to you can help the solution click for your child.

What’s the right amount of homework?

It’s often in first grade that kids start receiving regular homework and feel stressed and lost if they don’t complete it. If your child is having trouble adjusting to their new routines, know that it’s not just your child. Families all across America are having the same issues in terms of figuring out how to create quiet, focussed time for a young child to read, write, and do math inside a bustling home. In first grade, your child will likely be asked to do somewhere between 10 and 30 minutes of homework a night, sometimes in addition to 20 minutes of bedtime reading. ( The National PTA’s research-based recommendation is 10 to 20 minutes of homework a night in first grade and an additional 10 minutes per grade level thereafter.) If your child is getting a lot more than that, talk to your child’s teacher about how long your child should be spending on homework and what you can do to help.

Comparing U.S. homework time to other countries

If you’ve come from another country and recall your childhood homework taking less time, you may think it’s because you’re foreign. The truth is, most parents who grew up in the U.S. are feeling the same way. In the past few decades homework for younger grades has intensified in many schools. “The amount of homework that younger kids — ages 6 to 9 — have to do has gone up astronomically since the late ’80s,” says Alfie Kohn, author of the 2006 book The Homework Myth: Why Our Kids Get Too Much of a Bad Thing. So if you feel surprised about the quantity of homework your child is bringing home, you’re not alone.

According to an international study of homework, 15-year-olds in Shanghai do 13.8 hours of homework per week compared to 6.1 hours in the U.S. and 5.3 hours in Mexico and 3.4 hours in Costa Rica. But here’s the thing: academic expectations in the U.S. vary widely from school to school. Some American elementary schools have banned homework. Others pile on hours a night — even in the younger grades. By high school, though, most American students who are seriously preparing for four-year college are doing multiple hours of homework most nights.

Not into homework? Try this.

Homework detractors point to research that shows homework has no demonstrated benefits for students in the early elementary grades. “The research clearly shows that there is no correlation between academic achievement and homework, especially in the lower grades,” says Denise Pope, senior lecturer at the Stanford University Graduate School of Education and the author of the 2015 book, Overloaded and Underprepared: Strategies for Stronger Schools and Healthy Successful Kids .

On the other hand, nightly reading is hugely important.

“One thing we know does have a correlation with academic achievement is free reading time,” says Pope. “We know that that is something we want schools to encourage.” Since the scientific evidence shows the most impact comes from reading for pleasure, don’t skip bedtime reading. If your child is not being given any homework, make sure to spend some of that extra time reading books in either English or Spanish.

How Important Is Homework, And How Much Should Parents Help?

Please try again

A version of this post was  originally published  by Parenting Translator. Sign up for  the newsletter  and follow Parenting Translator  on Instagram .

In recent years, homework has become a very hot topic . Many parents and educators have raised concerns about homework and questioned how effective it is in enhancing students’ learning. There are also concerns that students may be getting too much homework, which ultimately interferes with quality family time and opportunities for physical activity and play . Research suggests that these concerns may be valid. For example, one study reported that elementary school students, on average, are assigned three times  the recommended amount of homework.

So what does the research say? What are the potential risks and benefits of homework, and how much is too much?

Academic benefits

First, research finds that homework is associated with higher scores on academic standardized tests for middle and high school students, but not elementary school students . A recent experimental study in Romania found some benefit for a small amount of writing homework in elementary students but not math homework. Yet, interestingly, this positive impact only occurred when students were given a moderate amount of homework (about 20 minutes on average).

Non-academic benefits

The goal of homework is not simply to improve academic skills. Research finds that homework may have some non-academic benefits, such as building responsibility , time management skills, and task persistence . Homework may also increase parents’ involvement in their children’s schooling. Yet, too much homework may also have some negative impacts on non-academic skills by reducing opportunities for free play , which is essential for the development of language, cognitive, self-regulation and social-emotional skills. Homework may also interfere with physical activity and too much homework is associated with an increased risk for being overweight . As with the research on academic benefits, this research also suggests that homework may be beneficial when it is minimal.

What is the “right” amount of homework?

Research suggests that homework should not exceed 1.5 to 2.5 hours per night for high school students and no more than one hour per night for middle school students. Homework for elementary school students should be minimal and assigned with the aim of building self-regulation and independent work skills. Any more than this and homework may no longer have a positive impact. 

The National Education Association recommends 10 minutes of homework per grade and there is also some experimental evidence that backs this up.

Overall translation

Research finds that homework provides some academic benefit for middle and high school students but is less beneficial for elementary school students. Research suggests that homework should be none or minimal for elementary students, less than one hour per night for middle school students, and less than 1.5 to 2.5 hours for high school students. 

What can parents do?

Research finds that parental help with homework is beneficial but that it matters more how the parent is helping rather than  how often  the parent is helping.

So how should parents help with homework, according to the research? 

• Focus on providing general monitoring, guidance and encouragement, but allow children to generate answers on their own and complete their homework as independently as possible . Specifically, be present while they are completing homework to help them to understand the directions, be available to answer simple questions, or praise and acknowledge their effort and hard work. Research shows that allowing children more autonomy in completing homework may benefit their academic skills.
• Only provide help when your child asks for it and step away whenever possible. Research finds that too much parental involvement or intrusive and controlling involvement with homework is associated with worse academic performance . 
• Help your children to create structure and develop some routines that help your child to independently complete their homework . Have a regular time and place for homework that is free from distractions and has all of the materials they need within arm’s reach. Help your child to create a checklist for homework tasks. Create rules for homework with your child. Help children to develop strategies for increasing their own self-motivation. For example, developing their own reward system or creating a homework schedule with breaks for fun activities. Research finds that providing this type of structure and responsiveness is related to improved academic skills.
• Set specific rules around homework. Research finds an association between parents setting rules around homework and academic performance. 
• Help your child to view homework as an opportunity to learn and improve skills. Parents who view homework as a learning opportunity (that is, a “mastery orientation”) rather than something that they must get “right” or complete successfully to obtain a higher grade (that is, a “performance orientation”) are more likely to have children with the same attitudes. 
• Encourage your child to persist in challenging assignments and emphasize difficult assignments as opportunities to grow . Research finds that this attitude is associated with student success. Research also indicates that more challenging homework is associated with enhanced academic performance.
• Stay calm and positive during homework. Research shows that mothers showing positive emotions while helping with homework may improve children’s motivation in homework.
• Praise your child’s hard work and effort during homework.   This type of praise is likely to increase motivation. In addition, research finds that putting more effort into homework may be associated with enhanced development of conscientiousness in children.
• Communicate with your child and the teacher about any problems your child has with homework and the teacher’s learning goals. Research finds that open communication about homework is associated with increased academic performance.

High-Quality Homework: How to Assign the Right Amount, and the Most Effective Formats of Homework

by Chandra Williams | Jul 16, 2019

SHARE THIS STORY

Although studies have shown that homework offers some benefits to students, assigning too much homework can actually cause students to experience higher stress levels and physical and mental health issues . In this article, we’ll discuss guidelines you can use to assign high quality homework for your students.

What is the “ten-minute homework guideline?”

The National PTA and National Education Association support the “ ten minute homework guideline ,” which suggests each student should have about ten minutes of homework per grade level. First-grade students should have between ten to twenty minutes of homework, with an additional ten minutes added for each subsequent grade level.

The ten-minute homework rule offers several benefits to students, including:

• Reduces the likelihood of students becoming overwhelmed.
• Prevents diminishing returns for academic success.
• Reduces the impact of the “homework gap,” a term indicating the disproportionate challenges faced by students who do not have access to the internet and other resources to complete homework assignments at their homes.
• Reduces impact on students who naturally take longer to complete homework assignments.

What purposes should homework accomplish?

Most homework assignments fall into one of the following four categories :

• Practice — Students have learned skills in class and practice using those skills on their own at home. For example, students learned the order of operations in math class and practice using these skills by solving some multi-step equations.
• Preparation — Students prepare to learn about a new concept in class the next day. For example, students read the first chapter of a new book which will be discussed in tomorrow’s English class.
• Study — Students review content they have already learned and practiced to prepare for a formative, unit, or benchmark assessment.
• Extend or Elaborate — Students have learned about a general concept in class, and complete individual work to expand their knowledge on the topic. For example, students learned about the formation of the United States in class, and each student will individually create a project exploring the history of a different state.

When students’ complete homework for the purpose of practicing skills, they may have single-skill assignments or cumulative assignments.

• Single-skill assignments are most effective when students need to master the skill taught in class. For example, students may list the steps of the scientific method.
• Cumulative assignments require students to decide which skill they need to use when solving a particular problem, and then properly use the skill. For example, students are presented with an experiment, must determine which steps in the scientific method need to be completed, and then must complete the experiment and demonstrate its results.

What is the most effective type of homework?

Existing studies have found that student performance is most positively affected when homework is used to build fluency, master new concepts, and proficiency. Students retain information better when the practice is conducted over several shorter sessions, rather than through one marathon session. Additionally, students should be able to use the same processes and skills with their homework assignments, which were modeled and demonstrated during class. In other words, homework assignments should be presented in the same format as classroom practices.

What are best practices for assigning homework?

Research suggests that homework is most effective when:.

• Assignments promote curiosity, leading to “ autonomous, self-directed learning .”
• Students have already “ demonstrated competence in the skill…before being asked to do it independently.”
• Teachers consider some students do not have access to the internet, a quiet working space, or homework help from parents or a tutor.
• Students understand the purpose of completing each homework assignment.
• Teachers provide feedback quickly, minimizing the chance for students to forget the assignment before they learn their scores.
• Teachers keep in mind that middle school and high school students may be assigned homework from all of their classes, and the ten-minute homework guideline applies to the combined homework load.

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."
