An increased level of collaboration is often a specific requirement for groups and agencies involved in complementary grant program activities. This ensures that programs with a common funding source are as efficient and effective as possible in areas where their missions converge. In this report, the authors highlight collaborative activities among two types of programs funded by the U.S. Department of Education's Office of Special Education Programs (OSEP)--state deaf-blind projects and parent centers. The ultimate purpose of this work is to create a system of collaboration between parent centers and state projects that can be sustained over time and promote a more equitable distribution of services to families across states. In this report, specific strategies are arranged by the following levels of collaboration: (1) Networking; (2) Cooperation; (3) Coordination; and (4) Collaboration.
