This practical book shares key lessons learned from highly effective, award-winning National Blue Ribbon Schools. Teacher Leadership Practice in High-Performing Schools explores the important role teachers have in leading schools, the balance administrators must strike between providing teachers with support and trusting them as professionals, and the ways that educators in these schools frequently collaborate across roles and do not operate in isolation. Following vignettes inspired by real schools, each chapter explains and unpacks key lessons learned, situates these lessons within the literature, offers readers robust tools to apply these lessons in their own schools, and includes questions designed to encourage reflection on school practices. This exciting new book helps schools, leadership teams, and individual educators reflect on teacher leadership practice in their schools and determine concrete next steps to increase and improve the impact of teacher leadership.
