Decreasing class sizes, even by as little as one student, comes with a price tag. It is possible to "pay" for this increase by compensating with one of the other factors influencing the salary cost of teachers: lower teachers' salaries, less required instruction time for students or more teaching time for teachers. Across OECD countries…

This study aims to understand the role of private secondary schools in rural Kenya under the Free Secondary Education Policy. Data were collected from four private schools over two months in 2018 and 2019. All the schools had experienced instability due to low enrolment, particularly after the policy was implemented in 2018. The decline in the…

Two seemingly different threads are in play on the issue of class size. The first is manifested in media reports that tell readers that class sizes are rising to concerning levels. The second thread appears in the work of some researchers and education leaders and suggests that repurposing class-size reduction funds to pay for other reforms may…

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…

A substantial amount of controversy surrounds the issue of class size in public schools. Parents and teachers are on one side, touting the benefits of smaller class sizes (e.g., increased academic achievement, greater student-teacher interaction, utilization of more innovative teaching strategies, and a decrease in discipline problems). On the…

Summarizes evidence for the effects of class-size reduction from experimental and nonexperimental measurements, addresses questions about the robustness of each type of estimate, and suggests hypotheses that could reconcile differences resulting from conflicting evidence. Discusses potential costs and the implications for future research into the…

Several dimensions of state-sponsored, reduced-class-size programs are addressed. At present, 20 states are contemplating following the lead of Indiana's PRIME TIME and Tennessee's STAR programs. Yet the effectivenessness of reduced class size in elementary schools continues to be uncertain and controversial. No one knows whether reduced class…

Most research on the positive effects of class-size reduction (CSR) has occurred in the elementary level (Word, Johnston, Bain, Fulton, Zaharias, Lintz, Achilles, Folger, & Breda, 1990; Molnar, Smith, Zahorik, Palmer, Halbach, & Ehrle, 1999). Is CSR an important variable in improving education in the middle grades? Can small classes be…

Estimates the operational costs of nationwide class-size-reduction programs under various policy alternatives, including the specified class size, flexibility in implementation, and whether the policy is targeted toward at-risk students. Depending on the options, estimated costs range from about $2 billion per year to over $11 billion per year.…
