"Peter DeWitt has provided us with a powerful and timely book on the growing phenomenon of ‘Collective Efficacy’. The Six Chapters contain a goldmine of ideas, resources, tools, surveys, action steps and reflective questions. What I like best is that the book is grounded equally in research and practice. This is an urgently needed book, and you will learn a lot from it!"

"While schools focus on common standards, data analysis, and increasing achievement, Peter DeWitt explains the critical nature of school climate and why, as the "5th C,” it is imperative for school success. As a school leader, Peter often asked thought-provoking questions, engaged in challenging conversations, and encouraged reflection, much as he does in Collaborative Leadership: A Collective Efficacy Approach to Improving School Climate. Through interesting vignettes, personal experience, and a variety of research, Peter provides a practical approach for growing a rich, safe environment."
