The purpose of this study is to test empirical models of variables posited to predict homework time management at the secondary school level. Student- and class-level predictors of homework time management were analyzed in a survey of 1895 students from 111 classes. Most of the variance in homework time management occurred at the student level, with parent education appearing as the only significant predictor at the class level. At the student level, the variation in homework time management was positively associated with self-reported grade, adult-oriented reasons for doing homework, learning-oriented reasons for doing homework, and student initiative in arranging the homework environment.
