High-quality out-of-school-time (OST) programs have a positive effect on youth development, but many cities have found it difficult to address the challenges of expanding and improving the quality of programs offered to underserved and high-need students. In response, The Wallace Foundation sponsored an initiative to help five cities increase collaboration, access, quality, information sharing, and sustainability in their OST systems. The overall goals of the initiative were to increase access, improve quality, develop information systems for decisionmaking, and plan for financial stability.
