The rise in the influence of and spending by educational philanthropists and foundations over the past two decades, especially in the area of market-based reforms, such as charter schools, vouchers, and merit pay, is evident across the United States. Largely due to philanthropic investments, relatively new educational intermediary organizations (IOs) have also been growing in size, scope, and influence. These new IOs have sought to implement market-based reforms in key urban school districts, frequently based on ideological stances and/or evidence of their efficacy. As yet, researchers have not conceptualized the unique position of foundations in the landscape of intermediary organizations, market-based reforms, and evidence production and utilization. Drawing from a 3-year (2011-2014) study of IOs, research utilization, and policymaking in the case of "incentivist" reforms, we find that foundations are uniquely situated in the reform landscape as a central actor, at the "hub" of intermediary activity as a funder of IOs, but also as a "spoke" in the wheel that helps to mobilize and, in many ways, direct the activities of the IOs. We discuss the implications of the role of foundations in research production, promotion, and utilization for research and policymaking.
