Prepared for a meeting of the Northwest Regional Exchange (NWRx) Advisory Board and its staff and consultants, this document first reviews nine reports' findings on nine hypotheses concerning the institutionalization of educational change or innovation, especially as institutionalization relates to the dissemination functions of state organizations in NWRx. For each hypothesis, supporting statements are provided from three or more of the reports. The nine hypotheses concern the role in institutionalization of the following incorporation or routinization of a project, a project's base of support and flexibility, location of administration, administrator involvement, contacts with influencial persons and the public, leadership quality and type, relationship to current practices and values, political environment and funding changes, and training of practitioners in the new function. The document then summarizes each of the nine reports. The reports include a theoretical model of institutionalization, a practitioner handbook, studies of innovations' institutionalization in urban bureaucracies and in a U.S. Marine Corps human relations program, and five studies of federally funded educational projects, involving the Elementary and Secondary Education Act, vocational education, reading, the Research and Development Utilization Program, state education agencies' roles in dissemination, and 250 Massachusetts projects.
