This book, The Challenges of School Reform: Impact, Implementation, and Sustainability, explores why reforms todate have failed to live up to expectations, and it discusses promising practices and strategies for sustaining increased student achievement. This work expands on the ideas and themes discussed in the first two volumes in this series on education policy: The first book-Talented Teachers: The Essential Force for Improving Student Achievement-examines the importance of teacher quality. Years of research have repeatedly confirmed what we inferred to be true-outside of the home environment, the quality of a student's teacher has the strongest impact on learning. After talented teachers were found to be a powerful component for bettering education, the second book-Improving Student Achievement: Reforms that Work-introduces reform ideas and programs that positively impact both teacher quality and student work. Now, The Challenges of School Reform: Implementation, Impact, and Sustainability deepens these discussions by exploring the answers to questions regarding ensuring the longevity and sustained success of effective school reform.
