Policymakers and researchers have now convinced themselves that the school is the unit of change. We see an accumulation of works and developments based on that assumption ranging from school-based management to the development planning for school change. School-based management refers to a form of educational administration where the school becomes the unit for decision-making as opposed to a central district administration (Caldwell and Wood, 1988). Developmental planning seeks to empower the school to deal more effectively with the task of improving teaching and learning (Hargreaves and Hopkins, 1991).
