How can an informed, evidence-based whole school approach to behaviour benefit you, your colleagues and your students? In this companion to Better Behaviour, Jarlath O'Brien combines insights from his own experience of improving behaviour in schools, research and policy in a practical guide to support current and aspiring school leaders. Through discussing the everyday issues that come with leading on behaviour, and casting a critical eye over sanctions, rewards and exclusions, this book encourages you to develop an approach that is firmly rooted in the values of your school, supports staff and will help navigate the challenges that can arise.
