The Cluster Schools Program attempted to restructure the governance structure in participating Newark (New Jersey) schools through shared decision making and site-based management. It also sought to foster strong links with other public and private institutions by establishing a collaborative that includes university participants among others. This report presents results of the first evaluation of program impact on the 10 participant schools. The evaluation relied on perceptions, attitudes, and behaviors of major participants. Questionnaires were completed by 4 central office personnel, 21 administrators, 187 teachers, and 274 parents. Highlights of findings are presented in the following areas: (1) the impact of organizational changes on schools; (2) the central office team; (3) endorsement of site-based management; (4) the level of involvement of schools and faculties in major program initiatives; (5) teacher perceptions of the impact of the Cluster Schools Program on bringing about change in the schools; and (6) the impact on student achievement. Highlighted findings underscore the need for the school district to look critically at the restructuring effort. Recommendations emphasize the importance of enhancing impact on the instructional program. Sixteen tables and four figures illustrate the evaluation. Three appendixes list collaborators, contain the study instruments, and give an achievement profile for cluster schools. (SLD)
