Education reform advocacy organizations have been working at the state-level for more than twenty-five years, but the last decade has seen a significant increase in their number and in the intensity of their focus and methods. It's no coincidence that as reform organizations proliferate the movement accelerates: the mission of such organizations is to build and mobilize a constituency for change. As the reform sector grows, many of the philanthropists who support this important work are asking for clarity about the unique contributions of groups working to advance education reform at the state-level. To address those important questions, leaders of several prominent national advocacy organizations, along with several leaders of single-state groups, gathered with the simple goal of delineating their respective efforts and fostering stronger working relationships across the sector. Leading education philanthropists commissioned this report to help them and other funders better understand the distinguishing contributions of all the reform players. Basic questions these funders regularly pose include: (1) Why are so many groups necessary?; (2) What distinguishes each player?; (3) Where and in what capacity are groups working?; (4) Who and what unique leverage does each bring to the table?; and (5) In what ways, if any, are these groups working together to advance common goals? This report answers those questions. It focuses on the organizations poised to play leading roles in shaping the overall policy framework at the district, state, and national level but focuses most heavily on the state-level, where the landscape is increasingly crowded. It gives special attention to the roles and distinctions among the national advocacy players that have emerged over the past decade. (Contains 4 figures and 5 footnotes.)
