What form of leadership promotes school improvement? How do schools build leadership capacity? How do schools sustain improvement in changing times? This book offers a new perspective on the relationship between leadership and school improvement. It emphasises the importance of maximising the leadership capabilities of all those within the organization, and offers guidance about the way in which this is achieved. Whilst drawing upon the latest research evidence concerning schools improvement, it is intended to be a practical guide to building leadership capacity and is written primarily for those working in schools. Through case study illustrations, Alma Harris and Linda Lambert demonstrate how leadership capacity can be built in schools in very different contexts. Practical material is provided to assist schools in generating the internal capacity for change and development. The central message of this book is one of investing in leadership at all levels within the organization to maintain and sustain school improvement.
