The report of the National Commission on Excellence in Education was quite critical of homework practices in U.S. high schools, and recommended increasing homework requirements as a means of improving student achievement. Here, we use data from the huge High School and Beyond longitudinal study to examine the effects of homework on achievement, with achievement measured both by test scores and by grades. Our results support the Commission's criticisms of low homework demands and grade inflation, and its recommendation for increased homework as an educational reform. We therefore urge school personnel to consider homework as a general educational intervention.
