Too Much Homework Is Bad for Kids

Piling on the homework doesn't help kids do better in school. In fact, it can lower their test scores.

That's the conclusion of a group of Australian researchers, who have taken the aggregate results of several recent studies investigating the relationship between time spent on homework and students' academic performance.

According to Richard Walker, an educational psychologist at Sydney University, data shows that in countries where more time is spent on homework, students score lower on a standardized test called the Program for International Student Assessment, or PISA. The same correlation is also seen when comparing homework time and test performance at schools within countries. Past studies have also demonstrated this basic trend.

Inundating children with hours of homework each night is detrimental, the research suggests, while an hour or two per week usually doesn't impact test scores one way or the other. However, homework only bolsters students' academic performance during their last three years of grade school. "There is little benefit for most students until senior high school (grades 10-12)," Walker told Life's Little Mysteries.
