This summary report presents the main findings and recommendations extracted from the SEA-PLM 2019 Main Regional Report (UNICEF & SEAMEO, 2020). We hope that this report, along with further national and regional research, offers a new policy momentum among Southeast Asian countries and partners. This work can then, in turn, assist the development of national and regional frameworks, actions, practices and research in key policy areas, and inform curriculum alignment, resource allocation, pedagogical practice, and planning at regional, national and sub-national levels.
