The National Education Association recommends no more than 10 minutes of homework per grade level.
That means a student in third grade should have no more than 30 minutes of homework a night and a sixth grader, no more than an hour. For high schoolers, the recommendation is two hours.
Often though, teachers fly in the face of the research by assigning much heavier loads, especially for middle and high school students.
