In an effort to reduce viral transmission, many schools are planning to reduce class size if they have not reduced it already. Yet the effect of class size on transmission is unknown. To determine whether smaller classes reduce school absence, especially when community disease prevalence is high, we merge data from the Project STAR randomized…

The Federal government will spend $1.2 billion in 1999-2000 on the Clinton administration's Class Size Reduction Initiative. Research on K-3 class-size reduction experiments (such as Tennessee's Project STAR) show positive achievement gains, particularly for minority and inner-city students. However, better teaching and learning must be a program…

This report, intended for local and state policy makers and practitioners, summarizes the findings and implications of class-size reduction (CSR) in California. The report's findings provide a comprehensive picture of California's CSR initiative during its first 2 years, covering such topics as implementation, resources, teacher qualifications,…

The Educational Priorities Panel carried out a study of the first year of the class size reduction program for grades K-3 in the New York City public schools by visiting five schools throughout the city and interviewing the principal and at least two teachers involved in implementing the program at each school. In all, 17 interviews were…

This paper begins by describing the basic design and scope of Tennessee's Student Teacher Achievement Ratio (Project STAR), which began in 1985. The project was designed to determine the effect of reduced class size on the achievement and development of students in kindergarten through grade three. Findings that demonstrated that students in…

As poverty, dysfunctional families, and special needs continue to affect students, educators seek improved ways to start children in formal education. One such approach is to lower the teacher-to-pupil ratios, and recent research shows that this method positively influences pupil achievement. How the process works is not well understood. To fill…

Although second- and third-year evaluations of California's K-3 class-size reduction program show modest achievement gains, these improvements have had large costs. Interdistrict inequities have been exacerbated as the teacher work force increased 38 percent, qualifications dropped, and implementation costs soared. Recommendations are discussed.…

During 1999/2000, the Saginaw, Michigan public schools implemented a reduced class size program in grades 1 and 2. At grade 1 (23 rooms), reduced-size classes were maintained at no more than 18 pupils; at grade 2 (5 rooms), the limit was 21 pupils. Comparison classes were identified to assess the impact of the program. Students in both conditions…

Examines four types of kindergarten programs (developmental, multiage, full-day, and lower class size) to determine which best accommodates developmental differences while enhancing youngsters' readiness for formal schooling. Low-income, urban areas should implement full-day kindergarten programs and smaller classes in first through third grades.…
