An organizational framework for establishing effective partnerships between school systems, social service providers, universities, and/or the private sector is presented in this paper. The different types of interorganizational structures, described along a continuum of increasing interdependence, include cooperative, coordinative, or collaborative arrangements. The different interorganizational conditions and interpersonal relationships of each arrangement are described in terms of the following features: interagency objectives, operating policies, interagency structure, personnel roles, resource allocation procedures, power and influence, and interagency relationships. Partnerships within schools are more likely to work under conditions that include the following: adequate resources and expertise; mutual responsibility of partners; the development of structures for planning and development; an organizational structure congruent to outcome; an equal focus on program development and the maintenance of positive partnership relationships; and periodic assessments and midcourse evaluations. Nine charts are included. (LMI)
