These training materials derive from a personnel preparation special project that developed, implemented, and evaluated a teaching model on collaborations necessary for effective delivery of early intervention. Module 1 provides an overview of the history of early intervention and the legal statutes that define early intervention. Module 2 describes ways in which agencies can share the responsibilities of providing services to the same audience, offers strategies for overcoming barriers, and discusses the process of building collaborative relationships. Module 3 introduces the concept of family-centered care as the foundation necessary for any collaborative relationship that provides service to children and describes the leading role the family plays in the development of the Individualized Family Service Plan. Module 4 discusses ways that early intervention service providers can work with the family to develop an early intervention program. This module covers the factors that affect the development and maintenance of the team, as well as strategies for overcoming barriers to the team process. The last module presents the service provider with the tools necessary to participate in a collaborative early intervention service delivery system. Specifically, the module focuses on the importance of communication, trust building, and negotiation. (CR)
