Before The Children’s Aid Society (CAS) opened its first two community schools in Washington Heights (1992–1993), our staff and board had already begun to address the issue of sustainability—that is, how to plan for the long-term development, implementation, assessment, and institutionalization of this new line of work. Internal strategic planning led to decisions by CAS board and staff leadership to realign existing resources in support of this new work, while external planning resulted in explicit partnership agreements, forged in 1990, with the New York City Board of Education and Community School District 6 (see appendix to Coltoff, ch. 1 in this volume) that also set the stage for long-term sustainability. As CAS’s assistant executive director for community schools, my responsibilities include planning and overseeing our sustainability efforts. This chapter describes CAS’s experience in raising funds for its community schools and offers suggestions for how other practitioners might proceed. CAS views sustainability as involving not only aggressive fundraising but also public relations, constituency building, and advocacy, using a conceptual framework developed by the Finance Project, a national research and policy organization. These four components are interrelated; work in one area supports and complements efforts in the other three. For fiscal year 2003–2004, the operating budget for CAS’s 10 community schools totaled almost $13 million, which included approximately $8.6 million for the extended-day, summer camp, teen, parent, and adult education components and $2.8 million for health services (medical, dental, and mental health). In addition, two sites have Early Head Start and Head Start programs operated by CAS; the costs for these programs are covered entirely by federal grants totaling approximately $1.4 million. Because the programs differ, each school has a different budget, but the estimated additional cost per student per year of a fully developed community school is $1,000. CAS generates support for its community schools from a wide variety of sources. During the initial years, core support came primarily from private sources, including foundations, corporations, and individuals; the exception was the health and mental health services, which were financed partially by Medicaid and Child Health Plus (federally supported children’s health insurance), as well as by other public and private sources.
