"This book could not be more timely. Community-based sanctions are attracting widespread attention, and many hope they will reduce recidivism and costs. But that won't happen unless we pay attention to implementation, the black box that Taxman and Belenko have unpacked in this outstanding book. Changing practice is more than just changing policies. Real change requires engaging community correctional agencies and their partners in the implementation process. This book provides new insights and a comprehensive framework for delivering programs that work and are sustainable. Any agency involved in implementing rehabilitation programs will be well advised to read this book closely. I highly recommend it." Joan Petersilia Adelbert H.
