Although not new, the concept of distributed (shared) leadership has re-emerged in recent years as one highly promising response to the complex challenges currently faced by schools. Responding productively to these challenges far exceeds the capacities of any individual leader. If schools are to flourish in the future, they will need to enlist the collective expertise of many more of their members and stakeholders than they have in the past. The purpose of this volume is to both present and synthesize the best available evidence about the nature, causes, and effects of distributed school leadership. The book also clarifies common misunderstandings about distributed leadership and identifies promising implications for practice and for future research.
