This Information Capsule examines the background and history in addition to research findings pertaining to class size reduction (CSR). This Capsule concludes that although educational researchers have not definitively agreed upon the effectiveness of CSR, given its almost universal public appeal, there is little doubt it is here to stay in some…

Class size reduction (CSR) has emerged as a very popular, if not highly controversial, policy approach for reducing the achievement gap. This article reports on findings from an implementation study of class size reduction policy in Wisconsin entitled the Student Achievement Guarantee in Education (SAGE). Drawing on case studies of nine schools,…

Evaluated Wisconsin's Student Achievement Guarantee in Education (SAGE) program of class-size reduction through a quasi-experimental, comparative-change design. Results for 1996-97 and 1997-98 are consistent with the positive effects shown for Tennessee's Student/Teacher Achievement Ratio program (STAR). (SLD)

Although class-size reductions cannot guarantee better student performance, the Tennessee and Wisconsin experiences, along with other studies, suggest that successful programs share key characteristics: concentration in the primary schooling years, classes with not more than 20 students, greater benefits for urban minority students, and alignment…

Researchers have long investigated whether smaller classes improve student achievement. Their conclusions suggest that class size reduction (CSR) can result in greater in-depth coverage of subject matter by teachers, enhanced learning and stronger engagement by students, more personalized teacher-student relationships, and safer schools with fewer…

This report summarizes research on the effects of class size reduction, outlines lessons learned from large-scale class size reduction initiatives in California and Wisconsin, and draws out implications of the research and lessons for class size reduction in North Carolina. The evidence that smaller classes promote increased learning is strongest…
