A study reviewed research on interagency relations involving vocational education and examined a local vocational agency and some of its linkages. It also determined what further research is needed to facilitate mutually advantageous interagency arrangements. The study used a dyadic perspective. An analytic model of interorganizational behavior, the Van de Ven model, was selected from the theoretical literature and used to analyze published reports of interorganizational relationships (IORs) and to design and conduct the field site study. The field site study focused on North Central Technical College in Mansfield, Ohio and its collaborative relationships with a secondary vocational school, regional medical facility, and an economic development consortium with emphasis on training. The application of the theoretical model to the three field site dyadic relationships supported the viability and usefulness of the model. The model was useful as a tool for understanding interorganizational causes and effects in all three cases. Factors found to be important in IORs included resource incentives, interdependency, commitment, a positive climate, and coordination. (Appendixes include the data framework for the field study, data summaries, and a supporting statement on interagency cooperation between vocational education and other state agencies.) (YLB)
