This book combines assemblage theory and policy mobilities to inform the study of comparative and international education (CIE), focusing on education policy and how such policy moves are enacted. These approaches challenge taken-for granted and universalizing concepts in policy research and policy work in CIE – such as the nation-state, policy making/policy enactment, global/local, Global North/Global South – and highlight how policy is contingent on emerging through complex relations between people and places. Using illustrative cases drawn from research and practice in CIE and education development, the book demonstrates how these ideas can be used in the analysis of policy and the application of this approach in real life.
