Through thorough scholarship, comprehensive knowledge, and creativity, this book fills that void' - James W. Guthrie, Patricia and Rodes Hart Professor of Educational Leadership and Public Policy, Vanderbilt University 'While offering no simple pathway to progress, this book reminds us how much more we can do to close achievement gaps' - Michael S.
