School leadership is critical to the success for both teachers and students. Yet, the theory and practice the informs the current context of school leadership has been, for the most part, left to each nation and its educational authorities, institutions, and associations. Thus, over the last several decades, global collaboration has not occurred in a significant manner. The purpose of this book is to encourage such discussion, examination, debate, and collaboration of the issues, challenges, and successes found in school leadership from around the world. Specific topics found in the book include international professional learning for school leaders from Canada, China, Europe, and Turkey, offering both theory and practices from the field of school leadership.
