This is the second evaluation of the Donors' Education Collaborative's (DEC) grant making since its founding in 1995. The first evaluation was a cross-case study of three projects that embodied DEC's theory of action: lasting systemic school reform demands sustained funding to build organizational collaboration that simultaneously broadens and deepens constituencies and employs strategies to effect policy change. This second evaluation follows the building of a multi-organization coalition focused on influencing a crosscutting issue--school governance--that has a powerful effect on the school reform work of each of the participating groups. Four DEC grantees, the Alliance for Quality Education (AQE), the Coalition for Educational Justice (CEJ), the Community Involvement Project of the Annenberg Institute for School Reform (CIP) and the New York Immigration Coalition (NYIC) are instrumental in this initiative. Because these groups have been DEC grantees previously, this effort provides an excellent opportunity to explore whether and how DEC's sustained support generates long-term benefits that accumulate over time. This evaluation can contribute further knowledge about DEC's strategy of sustained grant making and its focus on public engagement to foster systemic school reform.
