This book explores school leadership through a cross-cultural comparative lens, drawing on data from 16 countries located on five continents. The book gives a voice to both primary and secondary school principals, who discuss the nature of their work and explain their understanding of school leadership, strategies used to support their leadership, and how they 'do leadership' in a time of unprecedented change. The book highlights a number of important elements in school leadership: that it is personal and internally-motivated; change oriented and entrepreneurial; dependent on the qualities and motivations of school teachers; dependent on environmental factors related to economy, geography, political stability; heavily influenced by policies within and outside the field of education; and dependent on partnerships within and outside education. The book provides an authoritative cross-cultural account of what school leaders regard as school leadership. It will be essential reading for students, researchers and policy-makers in the fields of educational leadership and management, in particular those with an interest in comparative and international research, school leadership, and education policy.
