This Handbook explores discourse within the field of educational leadership and management. It provides a clear analysis of the current field as well as older foundational ideas and newer concepts which are beginning to permeate the discussion. The field of educational leadership and management has long acknowledged that educational contexts include a variety of leaders beyond head teachers and vice chancellors, such as informal and middle leaders. By looking at the knowledge dynamic rather than simply defining this Handbook allows research to be presented in its multidimensional, evolving reality.
