The 1989-90 Teacher Research and Computer Training Center Statewide Evaluation focused on the specific impact of six exemplary teacher center projects on teachers, schools, and students; 10 theme areas were identified for research. Evaluations were based on longitudinal, qualitative case studies of exemplary programs that have positively affected teacher education, interprofessional relationships among teachers, and the development of educational resources. Results of the study indicate that teacher centers reflect supportive and complementary relationships between the centers and their participating school districts. It is further noted that the impact of teacher centers on teachers has been positive not only for the teachers themselves, but also for the school community and the students. Although the six centers are not named, detailed information on their organizational context and operations is provided, as well as several recommendations for continued excellence and future research.
