An Irvine-commissioned white paper explores the range of ways private foundations can engage in public policy. The paper is by independent consultant Julia Coffman, who has worked with numerous foundations. She proposes a framework for public policy grantmaking. The paper suggests specific lessons that foundations should keep in mind when considering policy-related grantmaking, and highlights four case studies illustrating the variety of approaches foundations should consider. Irvine commissioned the paper to deepen the foundation’s and others’ understanding of policy-related grantmaking.
