This guide provides a framework for individuals and organizations to develop or strengthen local interagency linkage teams. The guide is revised from an earlier publication stemming from a project that facilitated the formation of local interagency linkage teams throughout Ohio. These teams focus on improving services to at-risk youth and adults through the development of collaborative interagency linkages. The guide proposes a series of steps, poses a number of questions, and provides planning forms and information about additional resources to assist interested persons in implementing the process of collaborative interagency linkage development to provide better services to at-risk clients. The process outlined in the guide is designed to help overcome many of the deterrents to interagency collaboration, such as shortage of time, lack of information, competition for scarce resources, distinct organizational structures, different geographical boundaries, and dissimilar calendars. The process includes a series of six steps, each forming a section of the guide: (1) assessing the local need and climate for interagency partnerships; (2) getting started; (3) forming the team; (4) establishing a collaborative relationship; (5) developing a plan; and (6) follow up and follow through. The guide includes three appendixes: an action plan form, a list of 19 agency resources and an annotated bibliography of 23 printed resources, and a synopsis of linkage projects in Ohio. (KC)
