Schools across the United States are facing budgetary pressures on a scale not seen in generations. Times of fiscal exigency force policymakers and education practitioners to pay more attention to the return on various categories of public investment in education. The sizes of the classes in which students are educated are often a focus of these…

Prior research has established the potential for achievement gains from attending smaller classes. However, large statewide class-size reduction (CSR) policies have not been found to consistently realize such gains. A leading explanation for the disappointing performance of CSR policies is that schools are forced to hire additional teachers of…

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…

Do smaller classes boost achievement mainly by helping teachers impart specific academic skills to students with low academic achievement? Or do they do so primarily by helping teachers engage poorly behaving students? The analysis uses the grade 3 to 4 transition in San Diego Unified School District as a source of exogenous variation in class…

California entered 2010-11 with a longstanding imbalance between ongoing spending and income. To help close that gap, state policymakers suspended Proposition 98, the minimum funding guarantee for K-12 schools and community colleges. In total, revenues for K-12 schools are down nearly 10% this year compared with 2007-08. Yet more cuts loom as the…

The California class size reduction program provided schools with cash rewards for K-3 classes of 20 or fewer students. I show how program rules made it possible for schools to save money by using mixed-grade classes to meet class size reduction obligations while maintaining larger average class sizes. I also show that this smoothing of students…

This paper investigates the effects of California's billion-dollar class-size-reduction program on student achievement. It uses year-to-year differences in class size generated by variation in enrollment and the state's class-size-reduction program to identify both the direct effects of smaller classes and related changes in teacher quality.…

This report presents a comprehensive preliminary analysis of how California's Class Size Reduction (CSR) initiative has impacted student achievement during the first 2 years of implementation. The analysis is based on complete student, classroom, and teacher records from 26,126 students in 1,174 classrooms from 83 schools in 8 Southern California…

California was, and remains, the largest "experiment" in class-size reduction (CSR) in the country's history. Its sweeping program to reduce the state's classes in kindergarten through the third grade covered nearly 2 million students and dropped the average class size from almost twenty-nine students per class, and often a great many…

Professional concern about the possible injurious effects of large classes and personal interest in various cognitive style variables led to this particular research at West Valley College (California). The belief persists among teachers, in spite of objective research, that small classes are better. Here, it was hypothesized that (1) class size…

Competing explanations of class size reduction effects on student academic achievement were tested using student, teacher, and school data collected from nearly 700 classrooms in over 70 schools during the first 3 years of implementation of California's (K-3) Class Size Reduction Program. Five major hypotheses were tested: (1) overall impact of…

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,…

Describes how the faculty of the College of Education at California State University, Long Beach, developed an academically rigorous, hands-on teacher credentialing program, with guaranteed results, to meet the demand created in July 1996 when the governor proposed an immediate reduction in class size to a 20-to-1 student/teacher ratio for grades…

Describes several prominent early grades small-class-size projects and their effects on student achievement: Indiana's Project Prime Time, Tennessee's Project STAR (Student/Teacher Achievement Ratio), Wisconsin's SAGE (Student Achievement Guarantee in Education) Program, and the California class-size-reduction program. Lists several conclusions,…

California's K-3 Class Size Reduction Initiative (1996) called for a 20:1 student-teacher ratio. Passage of this initiative created an unexpected teacher shortage and presented California teacher-education faculties with several dilemmas having long-term implications. When districts hired uncertified student teachers on an emergency-permit basis,…
