Over the past decade, the Association of Southeast Asian Nations (ASEAN) signed Mutual Recognition Arrangements (MRAs) in seven occupations, all designed to facilitate professional mobility within the region. MRAs are not easy to operationalize, however. Despite progress in key areas, member states face complex challenges as they move toward full implementation. This report is the latest in a project by the Asian Development Bank and the Migration Policy Institute to improve understanding of the barriers to the free movement of professionals within ASEAN and to support the development of strategies to overcome these hurdles. The report draws on the insights of nearly 400 ASEAN and member state officials, private sector employers, training directors, and others who participated in focus group discussions, meetings, and surveys.
