This report describes Philadelphia, Pennsylvania's, Alliance Organizing Project (AOP), which organized parents and families of Philadelphia's public school students to become full partners in Philadelphia school reform. It is one of five case studies in the Indicators Project on Education Organizing, which identified eight indicators of the impact of community organizing for school reform (leadership development, community power, social capital, public accountability, equity, school-community connection, positive school climate, and high quality curriculum and instruction). This report presents a model of the relationship of indicator areas to goals of the community organizing groups, introduces the AOP, describes the evolution of the AOP in the context of systemic reform, and discusses indicators and measures. It focuses on the AOP's accomplishments in four of the eight indicator areas: leadership development, school-community connection, social capital, and educational equity. The report concludes by looking at future directions in deepening, sustaining, and expanding school-level organizing; building on AOP's existing relationships with teachers; and impacting policy and system-wide change. Three appendices present definitions of the indicator areas, the Indicators Project advisory group, and AOP indicators charts (strategies, results, and data sources). (SM)
