"I have been waiting for this book for a decade. In an age in which the national debate on school reform is concerned principally with tactics and process, this volume focuses on the most important of all questions. What is the purpose of school? How do we know if a school is working? The authors are the most highly regarded names in education. This is an important book for anyone interested in schooling in America today."
