Is Homework a Waste of Students' Time? Study Finds It's the Biggest Cause of Teen Stress

As the debate over the need for homework continues, a new study found that it's the biggest cause of teen stress, leading to sleepless nights and poor academic performance

It’s the bane of every teen’s existence. After sitting through hours at school, they leave only to get started on mountains of homework. And educators are mixed on its effectiveness . Some say the practice reinforces what students learned during the day, while others argue that it put unnecessary stress on kids and parents , who are often stuck nagging or helping.

According to a new study, conducted by the Better Sleep Council , that homework stress is the biggest source of frustration for teens, with 74 percent of those surveyed ranking it the highest, above self-esteem (51 percent) parental expectations (45 percent) and bullying (15 percent).

Homework is taking up a large chunk of their time , too — around 15-plus hours a week, with about one-third of teens reporting that it’s closer to 20-plus hours.

The stress and excessive homework adds up to lost sleep, the BSC says. According to the survey, 57 percent of teenagers said that they don’t get enough sleep, with 67 reporting that they get just five to seven hours a night — a far cry from the recommended eight to ten hours. The BSC says that their research shows that when teens feel more stressed, their sleep suffers. They go to sleep later, wake up earlier and have more trouble falling and staying asleep than less-stressed teens.

“We’re finding that teenagers are experiencing this cycle where they sacrifice their sleep to spend extra time on homework, which gives them more stress — but they don’t get better grades,” said Mary Helen Rogers, the vice president of marketing and communications for the BSC.

Another interesting finding from this study: students who go to bed earlier and wake up earlier do better academically than those who stay up late, even if those night owls are spending that time doing homework.

To end this cycle of sleep deprivation and stress, the BSC recommends that students try setting a consistent time to go to sleep each night, regardless of leftover homework. And their other sleep tips are good for anyone, regardless of age — keep the temperature between 65 and 67 degrees, turn off the electronic devices before bed, make sure the mattress is comfy and reduce noise with earplugs or sound machines.

More than two hours of homework may be counterproductive, research suggests.

A Stanford education researcher found that too much homework can negatively affect kids, especially their lives away from school, where family, friends and activities matter.   "Our findings on the effects of homework challenge the traditional assumption that homework is inherently good," wrote Denise Pope , a senior lecturer at the Stanford Graduate School of Education and a co-author of a study published in the Journal of Experimental Education .   The researchers used survey data to examine perceptions about homework, student well-being and behavioral engagement in a sample of 4,317 students from 10 high-performing high schools in upper-middle-class California communities. Along with the survey data, Pope and her colleagues used open-ended answers to explore the students' views on homework.   Median household income exceeded $90,000 in these communities, and 93 percent of the students went on to college, either two-year or four-year.   Students in these schools average about 3.1 hours of homework each night.   "The findings address how current homework practices in privileged, high-performing schools sustain students' advantage in competitive climates yet hinder learning, full engagement and well-being," Pope wrote.   Pope and her colleagues found that too much homework can diminish its effectiveness and even be counterproductive. They cite prior research indicating that homework benefits plateau at about two hours per night, and that 90 minutes to two and a half hours is optimal for high school.   Their study found that too much homework is associated with:   • Greater stress : 56 percent of the students considered homework a primary source of stress, according to the survey data. Forty-three percent viewed tests as a primary stressor, while 33 percent put the pressure to get good grades in that category. Less than 1 percent of the students said homework was not a stressor.   • Reductions in health : In their open-ended answers, many students said their homework load led to sleep deprivation and other health problems. The researchers asked students whether they experienced health issues such as headaches, exhaustion, sleep deprivation, weight loss and stomach problems.   • Less time for friends, family and extracurricular pursuits : Both the survey data and student responses indicate that spending too much time on homework meant that students were "not meeting their developmental needs or cultivating other critical life skills," according to the researchers. Students were more likely to drop activities, not see friends or family, and not pursue hobbies they enjoy.   A balancing act   The results offer empirical evidence that many students struggle to find balance between homework, extracurricular activities and social time, the researchers said. Many students felt forced or obligated to choose homework over developing other talents or skills.   Also, there was no relationship between the time spent on homework and how much the student enjoyed it. The research quoted students as saying they often do homework they see as "pointless" or "mindless" in order to keep their grades up.   "This kind of busy work, by its very nature, discourages learning and instead promotes doing homework simply to get points," said Pope, who is also a co-founder of Challenge Success , a nonprofit organization affiliated with the GSE that conducts research and works with schools and parents to improve students' educational experiences..   Pope said the research calls into question the value of assigning large amounts of homework in high-performing schools. Homework should not be simply assigned as a routine practice, she said.   "Rather, any homework assigned should have a purpose and benefit, and it should be designed to cultivate learning and development," wrote Pope.   High-performing paradox   In places where students attend high-performing schools, too much homework can reduce their time to foster skills in the area of personal responsibility, the researchers concluded. "Young people are spending more time alone," they wrote, "which means less time for family and fewer opportunities to engage in their communities."   Student perspectives   The researchers say that while their open-ended or "self-reporting" methodology to gauge student concerns about homework may have limitations – some might regard it as an opportunity for "typical adolescent complaining" – it was important to learn firsthand what the students believe.   The paper was co-authored by Mollie Galloway from Lewis and Clark College and Jerusha Conner from Villanova University.

Is homework a necessary evil?

After decades of debate, researchers are still sorting out the truth about homework’s pros and cons. One point they can agree on: Quality assignments matter.

By Kirsten Weir

• Schools and Classrooms

Homework battles have raged for decades. For as long as kids have been whining about doing their homework, parents and education reformers have complained that homework's benefits are dubious. Meanwhile many teachers argue that take-home lessons are key to helping students learn. Now, as schools are shifting to the new (and hotly debated) Common Core curriculum standards, educators, administrators and researchers are turning a fresh eye toward the question of homework's value.

But when it comes to deciphering the research literature on the subject, homework is anything but an open book.

The 10-minute rule

In many ways, homework seems like common sense. Spend more time practicing multiplication or studying Spanish vocabulary and you should get better at math or Spanish. But it may not be that simple.

Homework can indeed produce academic benefits, such as increased understanding and retention of the material, says Duke University social psychologist Harris Cooper, PhD, one of the nation's leading homework researchers. But not all students benefit. In a review of studies published from 1987 to 2003, Cooper and his colleagues found that homework was linked to better test scores in high school and, to a lesser degree, in middle school. Yet they found only faint evidence that homework provided academic benefit in elementary school ( Review of Educational Research , 2006).

Then again, test scores aren't everything. Homework proponents also cite the nonacademic advantages it might confer, such as the development of personal responsibility, good study habits and time-management skills. But as to hard evidence of those benefits, "the jury is still out," says Mollie Galloway, PhD, associate professor of educational leadership at Lewis & Clark College in Portland, Oregon. "I think there's a focus on assigning homework because [teachers] think it has these positive outcomes for study skills and habits. But we don't know for sure that's the case."

Even when homework is helpful, there can be too much of a good thing. "There is a limit to how much kids can benefit from home study," Cooper says. He agrees with an oft-cited rule of thumb that students should do no more than 10 minutes a night per grade level — from about 10 minutes in first grade up to a maximum of about two hours in high school. Both the National Education Association and National Parent Teacher Association support that limit.

Beyond that point, kids don't absorb much useful information, Cooper says. In fact, too much homework can do more harm than good. Researchers have cited drawbacks, including boredom and burnout toward academic material, less time for family and extracurricular activities, lack of sleep and increased stress.

In a recent study of Spanish students, Rubén Fernández-Alonso, PhD, and colleagues found that students who were regularly assigned math and science homework scored higher on standardized tests. But when kids reported having more than 90 to 100 minutes of homework per day, scores declined ( Journal of Educational Psychology , 2015).

"At all grade levels, doing other things after school can have positive effects," Cooper says. "To the extent that homework denies access to other leisure and community activities, it's not serving the child's best interest."

Children of all ages need down time in order to thrive, says Denise Pope, PhD, a professor of education at Stanford University and a co-founder of Challenge Success, a program that partners with secondary schools to implement policies that improve students' academic engagement and well-being.

"Little kids and big kids need unstructured time for play each day," she says. Certainly, time for physical activity is important for kids' health and well-being. But even time spent on social media can help give busy kids' brains a break, she says.

All over the map

But are teachers sticking to the 10-minute rule? Studies attempting to quantify time spent on homework are all over the map, in part because of wide variations in methodology, Pope says.

A 2014 report by the Brookings Institution examined the question of homework, comparing data from a variety of sources. That report cited findings from a 2012 survey of first-year college students in which 38.4 percent reported spending six hours or more per week on homework during their last year of high school. That was down from 49.5 percent in 1986 ( The Brown Center Report on American Education , 2014).

The Brookings report also explored survey data from the National Assessment of Educational Progress, which asked 9-, 13- and 17-year-old students how much homework they'd done the previous night. They found that between 1984 and 2012, there was a slight increase in homework for 9-year-olds, but homework amounts for 13- and 17-year-olds stayed roughly the same, or even decreased slightly.

Yet other evidence suggests that some kids might be taking home much more work than they can handle. Robert Pressman, PhD, and colleagues recently investigated the 10-minute rule among more than 1,100 students, and found that elementary-school kids were receiving up to three times as much homework as recommended. As homework load increased, so did family stress, the researchers found ( American Journal of Family Therapy , 2015).

Many high school students also seem to be exceeding the recommended amounts of homework. Pope and Galloway recently surveyed more than 4,300 students from 10 high-achieving high schools. Students reported bringing home an average of just over three hours of homework nightly ( Journal of Experiential Education , 2013).

On the positive side, students who spent more time on homework in that study did report being more behaviorally engaged in school — for instance, giving more effort and paying more attention in class, Galloway says. But they were not more invested in the homework itself. They also reported greater academic stress and less time to balance family, friends and extracurricular activities. They experienced more physical health problems as well, such as headaches, stomach troubles and sleep deprivation. "Three hours per night is too much," Galloway says.

In the high-achieving schools Pope and Galloway studied, more than 90 percent of the students go on to college. There's often intense pressure to succeed academically, from both parents and peers. On top of that, kids in these communities are often overloaded with extracurricular activities, including sports and clubs. "They're very busy," Pope says. "Some kids have up to 40 hours a week — a full-time job's worth — of extracurricular activities." And homework is yet one more commitment on top of all the others.

"Homework has perennially acted as a source of stress for students, so that piece of it is not new," Galloway says. "But especially in upper-middle-class communities, where the focus is on getting ahead, I think the pressure on students has been ratcheted up."

Yet homework can be a problem at the other end of the socioeconomic spectrum as well. Kids from wealthier homes are more likely to have resources such as computers, Internet connections, dedicated areas to do schoolwork and parents who tend to be more educated and more available to help them with tricky assignments. Kids from disadvantaged homes are more likely to work at afterschool jobs, or to be home without supervision in the evenings while their parents work multiple jobs, says Lea Theodore, PhD, a professor of school psychology at the College of William and Mary in Williamsburg, Virginia. They are less likely to have computers or a quiet place to do homework in peace.

"Homework can highlight those inequities," she says.

Quantity vs. quality

One point researchers agree on is that for all students, homework quality matters. But too many kids are feeling a lack of engagement with their take-home assignments, many experts say. In Pope and Galloway's research, only 20 percent to 30 percent of students said they felt their homework was useful or meaningful.

"Students are assigned a lot of busywork. They're naming it as a primary stressor, but they don't feel it's supporting their learning," Galloway says.

"Homework that's busywork is not good for anyone," Cooper agrees. Still, he says, different subjects call for different kinds of assignments. "Things like vocabulary and spelling are learned through practice. Other kinds of courses require more integration of material and drawing on different skills."

But critics say those skills can be developed with many fewer hours of homework each week. Why assign 50 math problems, Pope asks, when 10 would be just as constructive? One Advanced Placement biology teacher she worked with through Challenge Success experimented with cutting his homework assignments by a third, and then by half. "Test scores didn't go down," she says. "You can have a rigorous course and not have a crazy homework load."

Still, changing the culture of homework won't be easy. Teachers-to-be get little instruction in homework during their training, Pope says. And despite some vocal parents arguing that kids bring home too much homework, many others get nervous if they think their child doesn't have enough. "Teachers feel pressured to give homework because parents expect it to come home," says Galloway. "When it doesn't, there's this idea that the school might not be doing its job."

Galloway argues teachers and school administrators need to set clear goals when it comes to homework — and parents and students should be in on the discussion, too. "It should be a broader conversation within the community, asking what's the purpose of homework? Why are we giving it? Who is it serving? Who is it not serving?"

Until schools and communities agree to take a hard look at those questions, those backpacks full of take-home assignments will probably keep stirring up more feelings than facts.

The Cult of Homework

America’s devotion to the practice stems in part from the fact that it’s what today’s parents and teachers grew up with themselves.

America has long had a fickle relationship with homework. A century or so ago, progressive reformers argued that it made kids unduly stressed , which later led in some cases to district-level bans on it for all grades under seventh. This anti-homework sentiment faded, though, amid mid-century fears that the U.S. was falling behind the Soviet Union (which led to more homework), only to resurface in the 1960s and ’70s, when a more open culture came to see homework as stifling play and creativity (which led to less). But this didn’t last either: In the ’80s, government researchers blamed America’s schools for its economic troubles and recommended ramping homework up once more.

The 21st century has so far been a homework-heavy era, with American teenagers now averaging about twice as much time spent on homework each day as their predecessors did in the 1990s . Even little kids are asked to bring school home with them. A 2015 study , for instance, found that kindergarteners, who researchers tend to agree shouldn’t have any take-home work, were spending about 25 minutes a night on it.

But not without pushback. As many children, not to mention their parents and teachers, are drained by their daily workload, some schools and districts are rethinking how homework should work—and some teachers are doing away with it entirely. They’re reviewing the research on homework (which, it should be noted, is contested) and concluding that it’s time to revisit the subject.

Read: My daughter’s homework is killing me

Hillsborough, California, an affluent suburb of San Francisco, is one district that has changed its ways. The district, which includes three elementary schools and a middle school, worked with teachers and convened panels of parents in order to come up with a homework policy that would allow students more unscheduled time to spend with their families or to play. In August 2017, it rolled out an updated policy, which emphasized that homework should be “meaningful” and banned due dates that fell on the day after a weekend or a break.

“The first year was a bit bumpy,” says Louann Carlomagno, the district’s superintendent. She says the adjustment was at times hard for the teachers, some of whom had been doing their job in a similar fashion for a quarter of a century. Parents’ expectations were also an issue. Carlomagno says they took some time to “realize that it was okay not to have an hour of homework for a second grader—that was new.”

Most of the way through year two, though, the policy appears to be working more smoothly. “The students do seem to be less stressed based on conversations I’ve had with parents,” Carlomagno says. It also helps that the students performed just as well on the state standardized test last year as they have in the past.

Earlier this year, the district of Somerville, Massachusetts, also rewrote its homework policy, reducing the amount of homework its elementary and middle schoolers may receive. In grades six through eight, for example, homework is capped at an hour a night and can only be assigned two to three nights a week.

Jack Schneider, an education professor at the University of Massachusetts at Lowell whose daughter attends school in Somerville, is generally pleased with the new policy. But, he says, it’s part of a bigger, worrisome pattern. “The origin for this was general parental dissatisfaction, which not surprisingly was coming from a particular demographic,” Schneider says. “Middle-class white parents tend to be more vocal about concerns about homework … They feel entitled enough to voice their opinions.”

Schneider is all for revisiting taken-for-granted practices like homework, but thinks districts need to take care to be inclusive in that process. “I hear approximately zero middle-class white parents talking about how homework done best in grades K through two actually strengthens the connection between home and school for young people and their families,” he says. Because many of these parents already feel connected to their school community, this benefit of homework can seem redundant. “They don’t need it,” Schneider says, “so they’re not advocating for it.”

That doesn’t mean, necessarily, that homework is more vital in low-income districts. In fact, there are different, but just as compelling, reasons it can be burdensome in these communities as well. Allison Wienhold, who teaches high-school Spanish in the small town of Dunkerton, Iowa, has phased out homework assignments over the past three years. Her thinking: Some of her students, she says, have little time for homework because they’re working 30 hours a week or responsible for looking after younger siblings.

As educators reduce or eliminate the homework they assign, it’s worth asking what amount and what kind of homework is best for students. It turns out that there’s some disagreement about this among researchers, who tend to fall in one of two camps.

In the first camp is Harris Cooper, a professor of psychology and neuroscience at Duke University. Cooper conducted a review of the existing research on homework in the mid-2000s , and found that, up to a point, the amount of homework students reported doing correlates with their performance on in-class tests. This correlation, the review found, was stronger for older students than for younger ones.

This conclusion is generally accepted among educators, in part because it’s compatible with “the 10-minute rule,” a rule of thumb popular among teachers suggesting that the proper amount of homework is approximately 10 minutes per night, per grade level—that is, 10 minutes a night for first graders, 20 minutes a night for second graders, and so on, up to two hours a night for high schoolers.

In Cooper’s eyes, homework isn’t overly burdensome for the typical American kid. He points to a 2014 Brookings Institution report that found “little evidence that the homework load has increased for the average student”; onerous amounts of homework, it determined, are indeed out there, but relatively rare. Moreover, the report noted that most parents think their children get the right amount of homework, and that parents who are worried about under-assigning outnumber those who are worried about over-assigning. Cooper says that those latter worries tend to come from a small number of communities with “concerns about being competitive for the most selective colleges and universities.”

According to Alfie Kohn, squarely in camp two, most of the conclusions listed in the previous three paragraphs are questionable. Kohn, the author of The Homework Myth: Why Our Kids Get Too Much of a Bad Thing , considers homework to be a “reliable extinguisher of curiosity,” and has several complaints with the evidence that Cooper and others cite in favor of it. Kohn notes, among other things, that Cooper’s 2006 meta-analysis doesn’t establish causation, and that its central correlation is based on children’s (potentially unreliable) self-reporting of how much time they spend doing homework. (Kohn’s prolific writing on the subject alleges numerous other methodological faults.)

In fact, other correlations make a compelling case that homework doesn’t help. Some countries whose students regularly outperform American kids on standardized tests, such as Japan and Denmark, send their kids home with less schoolwork , while students from some countries with higher homework loads than the U.S., such as Thailand and Greece, fare worse on tests. (Of course, international comparisons can be fraught because so many factors, in education systems and in societies at large, might shape students’ success.)

Kohn also takes issue with the way achievement is commonly assessed. “If all you want is to cram kids’ heads with facts for tomorrow’s tests that they’re going to forget by next week, yeah, if you give them more time and make them do the cramming at night, that could raise the scores,” he says. “But if you’re interested in kids who know how to think or enjoy learning, then homework isn’t merely ineffective, but counterproductive.”

His concern is, in a way, a philosophical one. “The practice of homework assumes that only academic growth matters, to the point that having kids work on that most of the school day isn’t enough,” Kohn says. What about homework’s effect on quality time spent with family? On long-term information retention? On critical-thinking skills? On social development? On success later in life? On happiness? The research is quiet on these questions.

Another problem is that research tends to focus on homework’s quantity rather than its quality, because the former is much easier to measure than the latter. While experts generally agree that the substance of an assignment matters greatly (and that a lot of homework is uninspiring busywork), there isn’t a catchall rule for what’s best—the answer is often specific to a certain curriculum or even an individual student.

Given that homework’s benefits are so narrowly defined (and even then, contested), it’s a bit surprising that assigning so much of it is often a classroom default, and that more isn’t done to make the homework that is assigned more enriching. A number of things are preserving this state of affairs—things that have little to do with whether homework helps students learn.

Jack Schneider, the Massachusetts parent and professor, thinks it’s important to consider the generational inertia of the practice. “The vast majority of parents of public-school students themselves are graduates of the public education system,” he says. “Therefore, their views of what is legitimate have been shaped already by the system that they would ostensibly be critiquing.” In other words, many parents’ own history with homework might lead them to expect the same for their children, and anything less is often taken as an indicator that a school or a teacher isn’t rigorous enough. (This dovetails with—and complicates—the finding that most parents think their children have the right amount of homework.)

Barbara Stengel, an education professor at Vanderbilt University’s Peabody College, brought up two developments in the educational system that might be keeping homework rote and unexciting. The first is the importance placed in the past few decades on standardized testing, which looms over many public-school classroom decisions and frequently discourages teachers from trying out more creative homework assignments. “They could do it, but they’re afraid to do it, because they’re getting pressure every day about test scores,” Stengel says.

Second, she notes that the profession of teaching, with its relatively low wages and lack of autonomy, struggles to attract and support some of the people who might reimagine homework, as well as other aspects of education. “Part of why we get less interesting homework is because some of the people who would really have pushed the limits of that are no longer in teaching,” she says.

“In general, we have no imagination when it comes to homework,” Stengel says. She wishes teachers had the time and resources to remake homework into something that actually engages students. “If we had kids reading—anything, the sports page, anything that they’re able to read—that’s the best single thing. If we had kids going to the zoo, if we had kids going to parks after school, if we had them doing all of those things, their test scores would improve. But they’re not. They’re going home and doing homework that is not expanding what they think about.”

“Exploratory” is one word Mike Simpson used when describing the types of homework he’d like his students to undertake. Simpson is the head of the Stone Independent School, a tiny private high school in Lancaster, Pennsylvania, that opened in 2017. “We were lucky to start a school a year and a half ago,” Simpson says, “so it’s been easy to say we aren’t going to assign worksheets, we aren’t going assign regurgitative problem sets.” For instance, a half-dozen students recently built a 25-foot trebuchet on campus.

Simpson says he thinks it’s a shame that the things students have to do at home are often the least fulfilling parts of schooling: “When our students can’t make the connection between the work they’re doing at 11 o’clock at night on a Tuesday to the way they want their lives to be, I think we begin to lose the plot.”

When I talked with other teachers who did homework makeovers in their classrooms, I heard few regrets. Brandy Young, a second-grade teacher in Joshua, Texas, stopped assigning take-home packets of worksheets three years ago, and instead started asking her students to do 20 minutes of pleasure reading a night. She says she’s pleased with the results, but she’s noticed something funny. “Some kids,” she says, “really do like homework.” She’s started putting out a bucket of it for students to draw from voluntarily—whether because they want an additional challenge or something to pass the time at home.

Chris Bronke, a high-school English teacher in the Chicago suburb of Downers Grove, told me something similar. This school year, he eliminated homework for his class of freshmen, and now mostly lets students study on their own or in small groups during class time. It’s usually up to them what they work on each day, and Bronke has been impressed by how they’ve managed their time.

In fact, some of them willingly spend time on assignments at home, whether because they’re particularly engaged, because they prefer to do some deeper thinking outside school, or because they needed to spend time in class that day preparing for, say, a biology test the following period. “They’re making meaningful decisions about their time that I don’t think education really ever gives students the experience, nor the practice, of doing,” Bronke said.

The typical prescription offered by those overwhelmed with homework is to assign less of it—to subtract. But perhaps a more useful approach, for many classrooms, would be to create homework only when teachers and students believe it’s actually needed to further the learning that takes place in class—to start with nothing, and add as necessary.

Is Homework Valuable or Not? Try Looking at Quality Instead

Is there an end in sight to the “homework wars?”

Homework is one those never-ending debates in K-12 circles that re-emerges every few years, bringing with it a new collection of headlines. Usually they bemoan how much homework students have, or highlight districts and even states that have sought to cap or eliminate homework .

Now, a new analysis from the Center for American Progress suggests a more fruitful way of thinking about this problem. Maybe, it suggests, what we should be doing is looking at what students are routinely being asked to do in take-home assignments, how well that homework supports their learning goals (or doesn’t), and make changes from there.

The analysis of nearly 200 pieces of homework concludes that much of what students are asked to do aligns to the Common Core State Standards—a testament to how pervasive the standards are in the U.S. education system, even though many states have tweaked, renamed, or replaced them. However, most of the homework embodied basic, procedural components of the standards, rather than the more difficult skills—such as analyzing or extending their knowledge to new problems.

“We were surprised by the degree of alignment. And we were also surprised by the degree that the homework was rote, and how much some of this stuff felt like Sudoku,” said Ulrich Boser, a senior fellow at CAP. “It made the homework debate make a lot more sense about why parents are frustrated.”

It is also similar to the findings of groups like the Education Trust, which have found that classwork tends to be aligned to state standards, but not all that rigorous.

Collecting Homework Samples

The CAP analysis appears to be one of the first studies to look at homework rigor using a national survey lens. Many studies of homework are based on one school or one district’s assignments, which obviously limits their applicability. Attempts to synthesize all this research have led to some hard-to-parse conclusions. One of the most cited studies concludes there’s some connection for grades 6-12 between homework and test scores, but less so for elementary students, and less of an impact on actual grades.

Another problem is that students’ experiences with homework seem to vary so dramatically: A Brookings Institution report based on survey data from the National Assessment of Educational Progress concluded that, while on average students aren’t overburdened by homework, a subset of students do appear to get hours upon hours.

The CAP analysis, instead, was based on getting a sample of parents from across the country to send in examples of their children’s homework. The researchers used MTurk, a crowdsourcing service offered by Amazon.com to recruit parents. Of the 372 parents who responded, the researchers got a pile of 187 useable assignments. Next, John Smithson, an emeritus researcher at the University of Wisconsin-Madison, had teams grade them on a taxonomy looking at both the content and the “cognitive demand,” or difficulty, of the work. The index fell on a 1 to 10 scale, with a score 4 to 6 range considered as “good” alignment.

The results? On average, math assignments fell within this range, while the ELA ones were slightly weaker, in the 3 to 5 range.

But the real eye-opening graphic is this one, which shows that by far the assignments were mostly low-level.

This makes some logical sense when you think about it. Just as with teaching and testing, it is much easier to write homework assignments prioritizing basic arithmetic drills and fill-in-the-blank vocabulary words than ones that get students to “prove” or “generalize” some tenet. (I suspect prepackaged curricula, too, probably lean more toward rote stuff than cognitively demanding exercises.)

Here’s another explanation: Many teachers believe homework should be for practicing known content, not learning something new. This is partially to help close the “homework gap” that surfaces because some students can access parent help or help via technology, while other students can’t. It’s possible that teachers are purposefully giving lower-level work to their students to take home for this reason.

To be sure, Boser said, it’s not that all lower-level work is intrinsically bad: Memorization does have a place in learning. But assignments like color-in-the-blank and word searches are probably just a waste of students’ time. “Homework assignments,” the study says, “should be thought-provoking.”

Study Limitations

The study does come with some significant limitations, so you must use caution in discussing its results. The surveyed population differs from the population at large, overrepresenting mothers over fathers and parents of K-5 students, and underrepresenting black parents. Also, the majority of the assignments the parents sent in came from the elementary grades.

The report makes suggestions on how districts can strategically improve the quality of their homework, rather than deciding to chuck it out altogether.

One is to is to audit homework assignments to make sure they’re actually useful at building some of the more difficult skills. Another is to extend the “curriculum revolution” of the last decade, which has focused more attention on the quality and alignment of textbooks and materials, to homework. A third is to use appropriate technology so students can access out-of-school supports for challenging homework.

Is Homework Good for Kids? Here’s What the Research Says

A s kids return to school, debate is heating up once again over how they should spend their time after they leave the classroom for the day.

The no-homework policy of a second-grade teacher in Texas went viral last week , earning praise from parents across the country who lament the heavy workload often assigned to young students. Brandy Young told parents she would not formally assign any homework this year, asking students instead to eat dinner with their families, play outside and go to bed early.

But the question of how much work children should be doing outside of school remains controversial, and plenty of parents take issue with no-homework policies, worried their kids are losing a potential academic advantage. Here’s what you need to know:

For decades, the homework standard has been a “10-minute rule,” which recommends a daily maximum of 10 minutes of homework per grade level. Second graders, for example, should do about 20 minutes of homework each night. High school seniors should complete about two hours of homework each night. The National PTA and the National Education Association both support that guideline.

But some schools have begun to give their youngest students a break. A Massachusetts elementary school has announced a no-homework pilot program for the coming school year, lengthening the school day by two hours to provide more in-class instruction. “We really want kids to go home at 4 o’clock, tired. We want their brain to be tired,” Kelly Elementary School Principal Jackie Glasheen said in an interview with a local TV station . “We want them to enjoy their families. We want them to go to soccer practice or football practice, and we want them to go to bed. And that’s it.”

A New York City public elementary school implemented a similar policy last year, eliminating traditional homework assignments in favor of family time. The change was quickly met with outrage from some parents, though it earned support from other education leaders.

New solutions and approaches to homework differ by community, and these local debates are complicated by the fact that even education experts disagree about what’s best for kids.

The research

The most comprehensive research on homework to date comes from a 2006 meta-analysis by Duke University psychology professor Harris Cooper, who found evidence of a positive correlation between homework and student achievement, meaning students who did homework performed better in school. The correlation was stronger for older students—in seventh through 12th grade—than for those in younger grades, for whom there was a weak relationship between homework and performance.

Cooper’s analysis focused on how homework impacts academic achievement—test scores, for example. His report noted that homework is also thought to improve study habits, attitudes toward school, self-discipline, inquisitiveness and independent problem solving skills. On the other hand, some studies he examined showed that homework can cause physical and emotional fatigue, fuel negative attitudes about learning and limit leisure time for children. At the end of his analysis, Cooper recommended further study of such potential effects of homework.

Despite the weak correlation between homework and performance for young children, Cooper argues that a small amount of homework is useful for all students. Second-graders should not be doing two hours of homework each night, he said, but they also shouldn’t be doing no homework.

Not all education experts agree entirely with Cooper’s assessment.

Cathy Vatterott, an education professor at the University of Missouri-St. Louis, supports the “10-minute rule” as a maximum, but she thinks there is not sufficient proof that homework is helpful for students in elementary school.

“Correlation is not causation,” she said. “Does homework cause achievement, or do high achievers do more homework?”

Vatterott, the author of Rethinking Homework: Best Practices That Support Diverse Needs , thinks there should be more emphasis on improving the quality of homework tasks, and she supports efforts to eliminate homework for younger kids.

“I have no concerns about students not starting homework until fourth grade or fifth grade,” she said, noting that while the debate over homework will undoubtedly continue, she has noticed a trend toward limiting, if not eliminating, homework in elementary school.

The issue has been debated for decades. A TIME cover in 1999 read: “Too much homework! How it’s hurting our kids, and what parents should do about it.” The accompanying story noted that the launch of Sputnik in 1957 led to a push for better math and science education in the U.S. The ensuing pressure to be competitive on a global scale, plus the increasingly demanding college admissions process, fueled the practice of assigning homework.

“The complaints are cyclical, and we’re in the part of the cycle now where the concern is for too much,” Cooper said. “You can go back to the 1970s, when you’ll find there were concerns that there was too little, when we were concerned about our global competitiveness.”

Cooper acknowledged that some students really are bringing home too much homework, and their parents are right to be concerned.

“A good way to think about homework is the way you think about medications or dietary supplements,” he said. “If you take too little, they’ll have no effect. If you take too much, they can kill you. If you take the right amount, you’ll get better.”

Nobody knows what the point of homework is

The homework wars are back.

by Jacob Sweet

As the Covid-19 pandemic began and students logged into their remote classrooms, all work, in effect, became homework. But whether or not students could complete it at home varied. For some, schoolwork became public-library work or McDonald’s-parking-lot work.

Luis Torres, the principal of PS 55, a predominantly low-income community elementary school in the south Bronx, told me that his school secured Chromebooks for students early in the pandemic only to learn that some lived in shelters that blocked wifi for security reasons. Others, who lived in housing projects with poor internet reception, did their schoolwork in laundromats.

According to a 2021 Pew survey , 25 percent of lower-income parents said their children, at some point, were unable to complete their schoolwork because they couldn’t access a computer at home; that number for upper-income parents was 2 percent.

The issues with remote learning in March 2020 were new. But they highlighted a divide that had been there all along in another form: homework. And even long after schools have resumed in-person classes, the pandemic’s effects on homework have lingered.

Over the past three years, in response to concerns about equity, schools across the country, including in Sacramento, Los Angeles , San Diego , and Clark County, Nevada , made permanent changes to their homework policies that restricted how much homework could be given and how it could be graded after in-person learning resumed.

Three years into the pandemic, as districts and teachers reckon with Covid-era overhauls of teaching and learning, schools are still reconsidering the purpose and place of homework. Whether relaxing homework expectations helps level the playing field between students or harms them by decreasing rigor is a divisive issue without conclusive evidence on either side, echoing other debates in education like the elimination of standardized test scores from some colleges’ admissions processes.

I first began to wonder if the homework abolition movement made sense after speaking with teachers in some Massachusetts public schools, who argued that rather than help disadvantaged kids, stringent homework restrictions communicated an attitude of low expectations. One, an English teacher, said she felt the school had “just given up” on trying to get the students to do work; another argued that restrictions that prohibit teachers from assigning take-home work that doesn’t begin in class made it difficult to get through the foreign-language curriculum. Teachers in other districts have raised formal concerns about homework abolition’s ability to close gaps among students rather than widening them.

Many education experts share this view. Harris Cooper, a professor emeritus of psychology at Duke who has studied homework efficacy, likened homework abolition to “playing to the lowest common denominator.”

But as I learned after talking to a variety of stakeholders — from homework researchers to policymakers to parents of schoolchildren — whether to abolish homework probably isn’t the right question. More important is what kind of work students are sent home with and where they can complete it. Chances are, if schools think more deeply about giving constructive work, time spent on homework will come down regardless.

There’s no consensus on whether homework works

The rise of the no-homework movement during the Covid-19 pandemic tapped into long-running disagreements over homework’s impact on students. The purpose and effectiveness of homework have been disputed for well over a century. In 1901, for instance, California banned homework for students up to age 15, and limited it for older students, over concerns that it endangered children’s mental and physical health. The newest iteration of the anti-homework argument contends that the current practice punishes students who lack support and rewards those with more resources, reinforcing the “myth of meritocracy.”

But there is still no research consensus on homework’s effectiveness; no one can seem to agree on what the right metrics are. Much of the debate relies on anecdotes, intuition, or speculation.

Researchers disagree even on how much research exists on the value of homework. Kathleen Budge, the co-author of Turning High-Poverty Schools Into High-Performing Schools and a professor at Boise State, told me that homework “has been greatly researched.” Denise Pope, a Stanford lecturer and leader of the education nonprofit Challenge Success, said, “It’s not a highly researched area because of some of the methodological problems.”

Experts who are more sympathetic to take-home assignments generally support the “10-minute rule,” a framework that estimates the ideal amount of homework on any given night by multiplying the student’s grade by 10 minutes. (A ninth grader, for example, would have about 90 minutes of work a night.) Homework proponents argue that while it is difficult to design randomized control studies to test homework’s effectiveness, the vast majority of existing studies show a strong positive correlation between homework and high academic achievement for middle and high school students. Prominent critics of homework argue that these correlational studies are unreliable and point to studies that suggest a neutral or negative effect on student performance. Both agree there is little to no evidence for homework’s effectiveness at an elementary school level, though proponents often argue that it builds constructive habits for the future.

For anyone who remembers homework assignments from both good and bad teachers, this fundamental disagreement might not be surprising. Some homework is pointless and frustrating to complete. Every week during my senior year of high school, I had to analyze a poem for English and decorate it with images found on Google; my most distinct memory from that class is receiving a demoralizing 25-point deduction because I failed to present my analysis on a poster board. Other assignments really do help students learn: After making an adapted version of Chairman Mao’s Little Red Book for a ninth grade history project, I was inspired to check out from the library and read a biography of the Chinese ruler.

For homework opponents, the first example is more likely to resonate. “We’re all familiar with the negative effects of homework: stress, exhaustion, family conflict, less time for other activities, diminished interest in learning,” Alfie Kohn, author of The Homework Myth, which challenges common justifications for homework, told me in an email. “And these effects may be most pronounced among low-income students.” Kohn believes that schools should make permanent any moratoria implemented during the pandemic, arguing that there are no positives at all to outweigh homework’s downsides. Recent studies , he argues , show the benefits may not even materialize during high school.

In the Marlborough Public Schools, a suburban district 45 minutes west of Boston, school policy committee chair Katherine Hennessy described getting kids to complete their homework during remote education as “a challenge, to say the least.” Teachers found that students who spent all day on their computers didn’t want to spend more time online when the day was over. So, for a few months, the school relaxed the usual practice and teachers slashed the quantity of nightly homework.

Online learning made the preexisting divides between students more apparent, she said. Many students, even during normal circumstances, lacked resources to keep them on track and focused on completing take-home assignments. Though Marlborough Schools is more affluent than PS 55, Hennessy said many students had parents whose work schedules left them unable to provide homework help in the evenings. The experience tracked with a common divide in the country between children of different socioeconomic backgrounds.

So in October 2021, months after the homework reduction began, the Marlborough committee made a change to the district’s policy. While teachers could still give homework, the assignments had to begin as classwork. And though teachers could acknowledge homework completion in a student’s participation grade, they couldn’t count homework as its own grading category. “Rigorous learning in the classroom does not mean that that classwork must be assigned every night,” the policy stated . “Extensions of class work is not to be used to teach new content or as a form of punishment.”

Canceling homework might not do anything for the achievement gap

The critiques of homework are valid as far as they go, but at a certain point, arguments against homework can defy the commonsense idea that to retain what they’re learning, students need to practice it.

“Doesn’t a kid become a better reader if he reads more? Doesn’t a kid learn his math facts better if he practices them?” said Cathy Vatterott, an education researcher and professor emeritus at the University of Missouri-St. Louis. After decades of research, she said it’s still hard to isolate the value of homework, but that doesn’t mean it should be abandoned.

Blanket vilification of homework can also conflate the unique challenges facing disadvantaged students as compared to affluent ones, which could have different solutions. “The kids in the low-income schools are being hurt because they’re being graded, unfairly, on time they just don’t have to do this stuff,” Pope told me. “And they’re still being held accountable for turning in assignments, whether they’re meaningful or not.” On the other side, “Palo Alto kids” — students in Silicon Valley’s stereotypically pressure-cooker public schools — “are just bombarded and overloaded and trying to stay above water.”

Merely getting rid of homework doesn’t solve either problem. The United States already has the second-highest disparity among OECD (the Organisation for Economic Co-operation and Development) nations between time spent on homework by students of high and low socioeconomic status — a difference of more than three hours, said Janine Bempechat, clinical professor at Boston University and author of No More Mindless Homework .

When she interviewed teachers in Boston-area schools that had cut homework before the pandemic, Bempechat told me, “What they saw immediately was parents who could afford it immediately enrolled their children in the Russian School of Mathematics,” a math-enrichment program whose tuition ranges from $140 to about $400 a month. Getting rid of homework “does nothing for equity; it increases the opportunity gap between wealthier and less wealthy families,” she said. “That solution troubles me because it’s no solution at all.”

A group of teachers at Wakefield High School in Arlington, Virginia, made the same point after the school district proposed an overhaul of its homework policies, including removing penalties for missing homework deadlines, allowing unlimited retakes, and prohibiting grading of homework.

“Given the emphasis on equity in today’s education systems,” they wrote in a letter to the school board, “we believe that some of the proposed changes will actually have a detrimental impact towards achieving this goal. Families that have means could still provide challenging and engaging academic experiences for their children and will continue to do so, especially if their children are not experiencing expected rigor in the classroom.” At a school where more than a third of students are low-income, the teachers argued, the policies would prompt students “to expect the least of themselves in terms of effort, results, and responsibility.”

Not all homework is created equal

Despite their opposing sides in the homework wars, most of the researchers I spoke to made a lot of the same points. Both Bempechat and Pope were quick to bring up how parents and schools confuse rigor with workload, treating the volume of assignments as a proxy for quality of learning. Bempechat, who is known for defending homework, has written extensively about how plenty of it lacks clear purpose, requires the purchasing of unnecessary supplies, and takes longer than it needs to. Likewise, when Pope instructs graduate-level classes on curriculum, she asks her students to think about the larger purpose they’re trying to achieve with homework: If they can get the job done in the classroom, there’s no point in sending home more work.

At its best, pandemic-era teaching facilitated that last approach. Honolulu-based teacher Christina Torres Cawdery told me that, early in the pandemic, she often had a cohort of kids in her classroom for four hours straight, as her school tried to avoid too much commingling. She couldn’t lecture for four hours, so she gave the students plenty of time to complete independent and project-based work. At the end of most school days, she didn’t feel the need to send them home with more to do.

A similar limited-homework philosophy worked at a public middle school in Chelsea, Massachusetts. A couple of teachers there turned as much class as possible into an opportunity for small-group practice, allowing kids to work on problems that traditionally would be assigned for homework, Jessica Flick, a math coach who leads department meetings at the school, told me. It was inspired by a philosophy pioneered by Simon Fraser University professor Peter Liljedahl, whose influential book Building Thinking Classrooms in Mathematics reframes homework as “check-your-understanding questions” rather than as compulsory work. Last year, Flick found that the two eighth grade classes whose teachers adopted this strategy performed the best on state tests, and this year, she has encouraged other teachers to implement it.

Teachers know that plenty of homework is tedious and unproductive. Jeannemarie Dawson De Quiroz, who has taught for more than 20 years in low-income Boston and Los Angeles pilot and charter schools, says that in her first years on the job she frequently assigned “drill and kill” tasks and questions that she now feels unfairly stumped students. She said designing good homework wasn’t part of her teaching programs, nor was it meaningfully discussed in professional development. With more experience, she turned as much class time as she could into practice time and limited what she sent home.

“The thing about homework that’s sticky is that not all homework is created equal,” says Jill Harrison Berg, a former teacher and the author of Uprooting Instructional Inequity . “Some homework is a genuine waste of time and requires lots of resources for no good reason. And other homework is really useful.”

Cutting homework has to be part of a larger strategy

The takeaways are clear: Schools can make cuts to homework, but those cuts should be part of a strategy to improve the quality of education for all students. If the point of homework was to provide more practice, districts should think about how students can make it up during class — or offer time during or after school for students to seek help from teachers. If it was to move the curriculum along, it’s worth considering whether strategies like Liljedahl’s can get more done in less time.

Some of the best thinking around effective assignments comes from those most critical of the current practice. Denise Pope proposes that, before assigning homework, teachers should consider whether students understand the purpose of the work and whether they can do it without help. If teachers think it’s something that can’t be done in class, they should be mindful of how much time it should take and the feedback they should provide. It’s questions like these that De Quiroz considered before reducing the volume of work she sent home.

More than a year after the new homework policy began in Marlborough, Hennessy still hears from parents who incorrectly “think homework isn’t happening” despite repeated assurances that kids still can receive work. She thinks part of the reason is that education has changed over the years. “I think what we’re trying to do is establish that homework may be an element of educating students,” she told me. “But it may not be what parents think of as what they grew up with. ... It’s going to need to adapt, per the teaching and the curriculum, and how it’s being delivered in each classroom.”

For the policy to work, faculty, parents, and students will all have to buy into a shared vision of what school ought to look like. The district is working on it — in November, it hosted and uploaded to YouTube a round-table discussion on homework between district administrators — but considering the sustained confusion, the path ahead seems difficult.

When I asked Luis Torres about whether he thought homework serves a useful part in PS 55’s curriculum, he said yes, of course it was — despite the effort and money it takes to keep the school open after hours to help them do it. “The children need the opportunity to practice,” he said. “If you don’t give them opportunities to practice what they learn, they’re going to forget.” But Torres doesn’t care if the work is done at home. The school stays open until around 6 pm on weekdays, even during breaks. Tutors through New York City’s Department of Youth and Community Development programs help kids with work after school so they don’t need to take it with them.

As schools weigh the purpose of homework in an unequal world, it’s tempting to dispose of a practice that presents real, practical problems to students across the country. But getting rid of homework is unlikely to do much good on its own. Before cutting it, it’s worth thinking about what good assignments are meant to do in the first place. It’s crucial that students from all socioeconomic backgrounds tackle complex quantitative problems and hone their reading and writing skills. It’s less important that the work comes home with them.
