With the creation of the Effective Practice Incentive Community (EPIC), New Leaders for New Schools hoped to accomplish two broad and ambitious goals. The first was to identify and reward leadership practices driving significant achievement gains in high-poverty, urban schools. The second was to learn from those practices and make them more widely available, to educators in other high-need schools within the EPIC and New Leaders communities, and eventually to the broader community of educators committed to ensuring success for all students. Since 2008, EPIC has awarded $7.4 million dollars to 122 schools where effective practices have led to achievement gains--signifying clear progress toward the first goal. This review studies EPIC's Professional Learning Model, which is designed to help New Leaders take the "Knowledge System" from a build-it-and-they-will-come resource to a guided, field-based professional learning experience through which school leaders use the example of others to examine their own beliefs and practices and lead their own faculty and staff in meaningful change. The review outlines the key elements of EPIC's emerging professional learning model and positions it within the context of the research literature on effective leadership development and the National Staff Development Council's standards for professional learning. The goal is to provide a set of benchmarks that will assist the EPIC team in further refinement and implementation of the model. (Contains 35 notes.)
