An analysis of the internal organization of innovative secondary schools was developed from questionnaire response data supplied by the principals of 121 junior high, intermediate, and middle schools in 35 States. Criteria for comparison and evaluation were based primarily on related research and general organizational literature. The study found that the position of department head is the dominant organizational position and is used extensively by the principal to upgrade instruction. Of growing importance are a number of secondary positions, including teachers' advisory councils, curriculum coordinators, and intersubject instructional teams. Schools with a pupil-teacher ratio of 20:1 and under were more innovative and had more administrative positions than those with a higher ratio. Supporting data are compared on a percentage basis in 29 tables. Findings are illustrated by organizational charts for 15 representative schools and a prototype organizational chart. A bibliography of 58 items related to administration, management, and organization is appended. (JK)
