Research shows that some students regularly receive higher amounts of homework than experts recommend, which may cause stress and negative health effects.

Research suggests that when students are pushed to handle a workload that’s out of sync with their development level, it can lead to significant stress — for children and their parents.

Both the National Education Association (NEA) and the National PTA (NPTA) support a standard of “10 minutes of homework per grade level” and setting a general limit on after-school studying.

For kids in first grade, that means 10 minutes a night, while high school seniors could get two hours of work per night.

Experts say there may be real downsides for young kids who are pushed to do more homework than the “10 minutes per grade” standard.

“The data shows that homework over this level is not only not beneficial to children’s grades or GPA, but there’s really a plethora of evidence that it’s detrimental to their attitude about school, their grades, their self-confidence, their social skills, and their quality of life,” Donaldson-Pressman told CNN.

But the most recent study to examine the issue found that kids in their study who were in early elementary school received about three times the amount of recommended homework.

Published in The American Journal of Family Therapy, the 2015 study surveyed more than 1,100 parents in Rhode Island with school-age children.

The researchers found that first and second graders received 28 and 29 minutes of homework per night.

Kindergarteners received 25 minutes of homework per night, on average. But according to the standards set by the NEA and NPTA, they shouldn’t receive any at all.

A contributing editor of the study, Stephanie Donaldson-Pressman, told CNN that she found it “absolutely shocking” to learn that kindergarteners had that much homework.

And all those extra assignments may lead to family stress, especially when parents with limited education aren’t confident in their ability to talk with the school about their child’s work.

The researchers reported that family fights about homework were 200 percent more likely when parents didn’t have a college degree.

Some parents, in fact, have decided to opt out of the whole thing. The Washington Post reported in 2016 that some parents have just instructed their younger children not to do their homework assignments.

They report the no-homework policy has taken the stress out of their afternoons and evenings. In addition, it’s been easier for their children to participate in after-school activities.
