In the school-college partnership movement state policy can play an important role in sustaining partnerships as part of an active general strategy for educational change. Individual institutions and communities cannot solve the social problems facing the nation without working in cooperation with a broad network of other agencies and communities. Policymakers and educators have begun to re-examine the priorities and strategies that underlie domestic initiatives in the states and the nation. Collaboration has resulted in successful programs that make an impact on youth, families, education, and social systems. Recent collaborations have involved agencies and institutions planning together and setting mutual goals, engaging in collaborative action, trying to evaluate the impacts of collaborative strategies, and choosing joint budgeting. Successful collaboration involving higher education has three attributes: (1) mutual objectives driving joint planning, (2) new infrastructures that support collaborative goals, and (3) objective, long-term evaluation. State policy can support this movement by reviewing teacher education, interagency collaboration, and funding formulas and by considering policy levers such as incentives to foster multi-agency cooperation, coordination with federal programs, and expansion of existing partnerships. Eight key questions for state policy makers are suggested. (JB)
