This monograph treats collaboration between the university and the professions, both conceived as organizations that interact to achieve specified goals. It is part of the Continuing Professional Education Development Project, a five-year research effort to develop practice-oriented continuing professional education programs through collaboration between The Pennsylvania State University and six selected professions. The paper draws upon interorganizational relations theory for the concepts that undergird the notion of collaboration and moves to a less abstract level to present a model and a process for achieving the goals of collaboration. The paper has three parts. The first part is a development of the conceptual issues dealing with collaboration, cast into an interorganizational relations context. This part is followed by a definition and a model for collaboration, using the university and the professions as the two interacting organizations with the development of continuing professional education programs as the common goal. The third part describes an ongoing project that uses the model. A bibliography is included. (KC)
