Drawing on a range of contexts influenced by the Promise Neighborhoods Program--a federal place-based initiative to improve educational outcomes for students in distressed urban and rural neighborhoods--this book outlines effective characteristics and elements for implementing supplementary education. Chapter authors demonstrate that the disparities in educational achievement between white and non-white students can only be addressed by a holistic approach that takes the communities in which schools are situated as its focal point. This edited collection distills the insights gained from the communities implementing such comprehensive education programs and provides the framework and models for reproducing such successes.
