A large number of donor agencies, non-governmental organizations and governments have set up AEPs to meet the needs of over-age, out-of-school children and youth. These programs vary widely and are of differing quality and effectiveness. While there is guidance on quality education and education in emergencies generally, prior to this Guide, no AEP-specific Principles have existed to support these stakeholders in designing, implementing and evaluating their AEPs. With the goal of strengthening the quality of Accelerated Education (AE) programming through a more harmonized, standardized approach, the Accelerated Education Working Group, led by UNHCR and with representation from nine member organizations, has identified a set of 10 evidence-based Accelerated Education Principles. The Principles elaborated in this Guide help establish clear, common aspirations for AEPs globally.
