Praise/Testimonials

"Collective efficacy is among the most powerful influences on student learning, but also one of the hardest to implement. But Donohoo and Forbes do not shy away from the hard work. They identify the enablers and enemies of efficacy, the micro-moves to overcome these challenges, and a theory of action--all backed by research-based strategies to build collective efficacy in your school. Collective Impact is essential reading for anyone committed to transforming education through the power of collective teacher efficacy."
John Hattie, author of Visible Learning

"Collective Impact provides a clear path for building collective efficacy in our schools. While many educators are familiar with the research around how collective efficacy leads to increased student achievement, what's new here is an honest conversation about the barriers that get in the way of this important work. By clearly naming the twelve enemies of efficacy and providing strategies for overcoming them, the authors create a concrete and research-based vision of how schools rally around the belief that they can (and will) meet the needs of all students."
Diane Sweeney, author and consultant, Denver, Colorado

"You won't find a book that has more key ideas and guided solutions for pressing education issues than Collective Impact. Donohoo and Forbes set out twelve pairs of action choices that represent a map for turning your organization into a high-powered system. Use this book as a macro solution to examine all twelve twinned elements, or select any two or three pairs and work on them as a set. This book contains a goldmine of factors you can use to focus clearly and effectively on continuous efficacy."
Michael Fullan, professor emeritus, Ontario Institute for Studies in Education, University of Toronto

"Micro-moves: that's it! School leaders don't have time for complex multi-step processes that don't yield significant results. Donohoo and Forbes have curated the micro-moves needed for successful school leadership, all within a strong research-based frame. Prospective and current school leaders will keep this book on the corner of their desk."
Thomas Van Soelen, PhD, executive coach, Georgia Association of Educational Leaders
