This executive summary draws from P/PV's analysis of the implementation of the AfterZone initiative -- a citywide system-building effort in Providence, RI, that aims to provide high-quality, accessible out-of-school-time services to middle school youth. The executive summary defines AfterZone's unique multisite service delivery model, provides an overview of study's qualitative and quantitative research design, summarizes the key findings relating to student recruitment, and reflects on lessons for other cities seeking to build systems to expand and support their after-school offerings.
