Research suggests that students who do homework have higher achievement scores than students who do not do homework. (Cooper, 1994).
The amount of time a student spends on homework depends on a number of factors. The following chart is suggested as a general guide. It should be noted that times will vary from individual to individual, and at various times within a school year.
JK - Grade 3 = 10 - 30 minutes/night
Grade 4 - 6 = 30 - 60 minutes/night
Grade 7 - Grade 8 = 45 - 90 minutes/night
