Philanthropic involvement in education politics has become bolder and more visible. Have foundations changed funding strategies to enhance their political influence? Using data from 2000, 2005, and 2010, we investigate giving patterns among the 15 largest education foundations. Our analyses show growing support for national-level advocacy organizations. Furthermore, we find that foundations increasingly fund organizations that operate as "jurisdictional challengers" by competing with traditional public sector institutions. We apply social network analysis to demonstrate the growing prevalence of convergent grant-making--multiple foundations supporting the same organizations. These results suggest that a sector once criticized for not leveraging its investments now increasingly seeks to maximize its impact by supporting alternative providers, investing concurrently, and supporting grantees to engage in policy debates.
