Teacher leadership is a challenge. Frequently, those selected to serve as teacher leaders have no formal training and are provided with limited guidance. Yet, teachers expect teacher leaders to have an extensive "toolbox" containing strategies that can be used to improve educator effectiveness. This book is intended to provide teacher leaders with a repertoire of high-quality "tools" they can immediately and effectively use to complete their job responsibilities. More specifically, the reader will be provided with tools and strategies for leading groups and professional learning activities, collecting and analyzing data and student work, and organizing and facilitating mentoring programs and teacher action research projects. The teacher leader that reads this book will have the tools of a "master craftsman", making them capable of building a better future for teacher and their students.
