Optimal time per night spent on homework varies with grade level. For, primary, upper elementary, middle school, and high school grades, the optimal time is about 20, 40, 60, and 90 minutes, respectively. Homework is given often. Reports indicate that students may get as many 400 assignments per year in grades 7-10.
