"Developing Collaborative Expertise Teams by David Nagel and Bruce Potter is exactly the resource today’s schools need. As an experienced educator and school leader who has studied John Hattie’s research extensively and implemented both the Teacher Clarity Playbook and PLC+ Playbook, I approached this book with a critical eye, and was thoroughly impressed. This book strikes a powerful balance between theory and application. It is rich with practical tools, rubrics, self-assessments, case studies, and clear guidance for building collaborative expertise across any school setting. What makes it especially effective is its accessibility. Even readers unfamiliar with Hattie’s work will find the concepts approachable and the structure intuitive due to the authors’ clear writing style. I strongly recommend this book for publication. If I were in a position to purchase copies for my team, school, or district, I would do so without hesitation. It offers exactly what our leadership team needs to move forward with strategic coherence and deepen our culture of collaboration. In fact, we plan to use it as the foundation for a future book study and implementation cycle. This book has the potential to impact not just schools, but any organization striving for collective growth. It’s a timely and valuable contribution to the field."
