Social return on investment (SROI) offers a new strategy to measure and communicate the value of outcomes achieved by programs that provide social, health, and education services to children and their families. It can be a powerful tool for demonstrating the monetary value of programs and services and for communicating that value in a way that can be understood at a basic economic level. This case study of two community schools operated by The Children's Aid Society in partnership with the New York City Department of Education--PS 5 and Salomé Ureña--provides convincing results. It was prepared using a methodology developed by The Finance Project to help community school leaders measure and communicate the social and economic value of a community school and its programs. This methodology is presented in a companion guide. The findings provide clear quantitative evidence that investments in Children's Aid community schools are making a demonstrable difference in the community. The following are appended: (1) Community School Goals and Outcomes Crosswalk; (2) Data Inventory Worksheet; (3) Impact Maps by Site and Beneficiary; (4) Monetized Benefits; and (5) SROI Deadweight Rationale.
