This study documents the evolution and implementation of a program directed by the Council on Comprehensive Education (CCE) toward the purpose of realizing community control of a comprehensive high school in New York City. The program was one of nine at sites selected by the Documentation and Technical Assistance (DTA) Project as representing exemplary strategies for problem solving in urban schools. Chapter I outlines the history and purpose of CCE and the goals of the Westlake High School program. Chapter II of the report deals with the struggle for desegregation, decentralization, and community control in New York City during the 1960s discusses the CCE and the program site (Westlake High School) in this context. Chapter III reviews historical and political factors that influenced the development of an alternative educational concept at Westlake, and analyzes mechanisms used to maintain that concept in personnel and program changes. The fourth chapter describes the state of the collaborative structure as a problem solving strategy as it struggled to function in 1975, citing idealism and inflexibility on the part of the leaders as major barriers to adapting the program to the changing composition of the school and community. Chapter V highlights difficulties of the CCE project in 1975-76 and describes its demise. The report's final chapter analyzes lessons learned from the project . Appended are methodological descriptions and various forms and materials used in the project's implementation. (Author/GC)
