This newsletter briefly discusses the question of whether or not large secondary schools suffer from more problems than smaller schools and then examines the possibility of subdividing large schools through use of the "school-within-a-school" approach. Two different variations on the school-within-a-school approach are described, including structural subschools, where students are randomly assigned to different administrative units within a large school, and programmatic subschools, where students enroll in a program that focuses on one particular interest area or stresses a specific instructional approach. The second half of the publication presents short descriptions of seven secondary schools that are currently using some form of programmatic subschools, and of four secondary schools that are using some type of structural subschools.
