Drawing from the authors' extensive experience and research, - Unpacks questions around the nature of culture, including the importance of vision and climate and how the tension between the past and the future can keep a culture stagnant. - Explains how toxic cultures come about, why they can be so resistant to lasting change, and how not to change those cultures. - Describes how to build a positive culture based on trust, collaboration, and commitment rather than fear, competition, and compliance. - Offers advice to help leaders ensure that positive change endures, withstanding fads, toxic mindsets, and other threats. The authors provide real-world scenarios to illustrate how their ideas and approaches work in practice. Leaders will gain profound insight into how to create meaningful change, with the goal not just to "transform" their school but also to get all members of the school community to commit to culture change—and make sure that change sticks.
