This third volume of the final report on urban cooperative work education programs contains summaries or case studies of the programs in 19 secondary and 11 postsecondary schools throughout the country. (Volume 1, an overview of the entire study, describes the methodology and findings, and Volume 2 is a detailed analysis of the followup study of program graduates.) The case studies provide general descriptions of the 30 sample programs and illustrate how the principles of cooperative education were adapted to particular goals, local education agencies, school structures, and specific urban problems. Statistical data is presented on student enrollments, completions, placement and followup information, and student interviews. Each case study is divided into two sections: (1) Program description (purpose, participants, setting, administration and organization, history, student eligibility, program structure, job development, instruction, and student evaluation) and (2) issues (coordinator, counseling, promotion and public relations, advisory committee, work stations, career goals, and completion, placement, and followup).
