Educational specifications and user requirements for all types of intermediate schools (the middle school, the senior public school, and junior high schools) are presented. The essential purpose of this report is to provide educators and architects with general guidelines for designing improved school facilities. Part 1 focuses on the early adolescent and the cultural matrix in which the student and the school system coexist. Part 2 contains a thorough consideration of the very practical matters of cost and current practice. Part 3 serves as a planner's manual for each of the specialized areas within the intermediate school. Other areas covered include open learning areas, unified arts areas, enclosed learning areas, and administrative and ancillary areas. Tables, technical data sheets and illustrations are included for all areas. (RH)
