This book challenges dominant thinking about early career teachers and their work. It offers an in-depth and critical analysis of policies concerning the work of early career teachers and how they are supported during this critical period, when they are highly vulnerable to leaving the profession. Moreover, the book provides examples from actual practice that illustrate how to help early career teachers make a successful transition into the profession. These practices promote early career teachers’ development and help the profession as a whole to capitalize on the new knowledge and skills that these teachers bring to their classrooms and their students. The book is divided into two main parts. Part 1 deals with the difficult to define process of retaining early career teachers, and its respective chapters consider this broad issue from an international perspective. They explore how policies and practices have an impact on what happens in schools, and what it means to be a teacher and to teach. In turn, Part 2 focuses on the need to reconsider the policies and practices that create the ‘problem’ of early career teachers, and offers alternative ways forward. Each chapter addresses a specific aspect of the early career teacher retention issue, contributing to a greater understanding of how we can rethink the work of early career teachers so that they can more successfully transition into the profession.
