The movement of policy is a core feature of contemporary education reform. Many different concepts, including policy transfer, borrowing and lending, travelling, diffusion and mobility, have been deployed to study how and why policy moves across jurisdictions, scales of governance, policy sectors or organisations. However, the underlying theoretical perspectives and the foundational assumptions of different approaches to policy movement remain insufficiently discussed. To address this gap, this book places front and center questions of theory, ontology, epistemology and method related to policy movement. It explores a wide diversity of approaches to help understand the policy movement phenomena, providing a useful guide on global studies in education, as well as insights into the future of this dynamic area of work.
