Analyzed data from a five-year followup of students in Tennessee's Student/Teacher Achievement Ratio (STAR) project, a four-year large-scale randomized examination of the effects of class size on academic achievement. Results suggest that class-size benefits persist for at least five years and remain large enough to be important to educational…

Reviews Tennessee's Project Student/Teacher Achievement Ratio (STAR) and puts the results in the context of other nonexperimental evidence about class size. Nonexperimental evidence does not support any achievement gains attributable to class-size reduction, and empirical evidence from STAR has design and implementation flaws that cast doubt on…

Literature on the relation between class size and student achievement is reviewed, and policy alternatives are suggested. Class size reduction strategies, focusing on individual or small group tutoring, are proposed for primary and secondary instruction. Implementing these strategies requires ambitious staff development programs. (SLD)

Examines the origins of Tennessee's Project Student/Teacher Achievement Ratio (STAR) and explores what it was about Tennessee in the mid-1980s that fostered the development of this experimental approach to class size. Highlights the connection between the research world and the political world that resulted in the STAR project. (SLD)
