In this provocative and practical book, author Eric Nadelstern provides a proven-effective blueprint for narrowing the achievement gap in our schools, especially for children of colour who have been historically underserved. The author, one of the chief architects of the New York City reforms under Joel Klein, discusses the cutting-edge changes that were implemented in the last decade in NYC and identifies the ten most important lessons learned about whole-school-system improvement. In this last decade, NYC's public schools underwent extensive reforms that increased graduation rates by 30% the first significant increase in more than 50 years. For the first time, this book presents an insider's view of the 'Bloomberg-Klein years' and the reforms that transformed the nation's largest school system. 10 Lessons from New York City Schools is a must-read for those who believe schools can succeed and for all those who want to understand how.
