NCES reports surprising findings on homework

Following a cohort of children who were in Kindergarten in 1998-99, this study looked at homework assigned in 1st, 3rd & 5th grade.
"Children in schools with higher percentages of minority students had teachers who expected more homework on a typical evening, whereas generally children in lower minority schools had teachers who expected less homework. In addition, in all three grades, larger percentages of Black, Asian, and Hispanic children than White children had parents who reported that their child did homework five or more times a week."
