This report presents the results of an informal survey which focused upon the manner in which urban school systems are organized to perform the functions of utilization and dissemination of educational innovations. The systems of each of twenty-eight urban districts surveyed are briefly described. Results presented indicate that (1) all respondents identified the existence of informal mechanisms to keep up with new ideas in education; (2) respondents in approximately three out of four large urban districts were able to identify some type of formal process or arrangement; and (3) the structure and character of these arrangements varied significantly from district to district. Specific organizational structures and activities which support this process are detailed in attachments to this report. These include New York City's centralized structure, San Diego's teacher-based approach, and Cleveland's concerted efforts to achieve diffusion through its school-based reform project. (Author/EB)
