As countries strive to reform education systems and improve student results, school leadership is high on education policy agendas. But in many countries, the men and women who run schools are overburdened, underpaid and near retirement. Based on an OECD study of school leadership practices and policies around the world, and offering a cross country perspective, Volume 1 identifies four policy levers and a range of policy options to help governments improve school leadership now and build sustainable leadership for the future. Volume 2 explores what specialists are saying about system leadership for school improvement. Case studies examine innovative approaches to sharing leadership across schools in Belgium (Flanders), Finland and the United Kingdom (England) and leadership development programs for system improvement in Australia and Austria. As these are emerging practices, the book provides a first international comparison and assessment of the state of the art of system leadership.--Publisher's description.
