The completion of homework has been found to have a positive effect on academic achievement, particularly for high school students (Cooper, Robinson and Patall 2006). In 2007, parents reported that their high school students spent an average of 7 hours per week on homework.12 About 42 percent of parents reported that their children did homework 5 or more days per week, while 5 percent reported that their children did homework less than once per week. Overall, 65 percent of parents reported that they checked to make sure that their high school students' homework was done.
Parents of Asian high school students reported that they spent more hours per week on homework (10 hours on average) than did students of all other races/ethnicities shown (who spent an average of 6 to 7 hours per week on homework). Additionally, 68 percent of Asian parents reported that their students did homework 5 or more days per week, compared with 44 percent of White parents, 30 percent of Black parents, and 40 percent of Hispanic parents. Comparing parents of Asian students and parents of students of two or more races, there was no measurable difference between those groups in the percentage who reported that their children did homework 5 or more days per week.
A higher percentage of Black students (83 percent) had parents who reported that they checked to make sure that their students' homework was done, compared with parents of White students (57 percent), Asian students (59 percent), and students of two or more races (66 percent). In addition, 76 percent of Hispanic parents reported checking homework, higher than the percentage of White or Asian parents who did so.
