This policy brief examines some of the major funding sources of the school choice movement and their potential impact on policy. While some data--such as contributions from individuals and local unions--are not included because of the lack of access to information, this snapshot of major grants and contributors is revealing. Funding sources for both advocates and opposing forces are examined. Data were drawn from several sources, including individual websites of foundations and other organizations; informational databases of foundations and of grant recipients; and foundations’ tax filings, which list their dispersals. This policy brief also explores strategies funders use to reach the media, policymakers, and the public in their efforts to promote or impede the school choice movement.
