This report evaluates the operation and effects of a work-study program among high school juniors and seniors following its extension to municipal agencies of the city of New York. The evaluation forms part of a five year program, and constitutes an internal self-examination of the administrative and operational aspects of the institutions. The study examines the program's effects upon students' goals, and its service to the community. Two methods were utilized for coordinating school and work experiences--full-time employment of students on an alternate week or two-week basis, and a daily work-study plan, where students attend school each morning and are employed in the afternoon. Five major schools visited were selected for control studies. Descriptive analyses were made of the administration of the various aspects and departments of the program. Through interview information, the attitudes of supervisory personnel in city departments to the program were assessed; in 1964, this was effected by means of a questionnaire Student attitudes were evaluated through a questionnaire relating to work experiences and school learning. In general, the school performance of the project students was found to be slightly superior to the comparable performance of their control group peers. Principals were found to be generally favorable toward the program. Student attitudes toward the program were also found to be positive. (RJ)
