Book excerpt: In their follow-up to School Culture Recharged and the best-selling School Culture Rewired, Steve Gruenert and Todd Whitaker go deep into the roots of culture change and explore how school leaders can positively shift their cultures in a sustainable way. Drawing from the authors' extensive experience and research, Committing to the Culture - 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.
