Urban school reformers for decades have tried to improve educational outcomes for underserved and disadvantaged students, with the assistance of constantly evolving federal and state policies. In recent years, education policies have shifted from targeting individual students to developing universal standards for teaching and learning, and comprehensive school reform (CSR) has emerged as an effective key model. The federal CSR program seeks to support the implementation of comprehensive school reform, especially in high-poverty schools, and to improve efforts to help all children meet challenging academic standards. Schools that receive federal CSR funds must adopt approaches that comply with the No Child Left Behind Act (NCLB). This book provides a series of studies and reflections on CSR by leading experts in the field.
