This report examines the evolving landscape of adult education and training (AET). It maps existing quality assurance systems across OECD countries and introduces a framework for comparison. The report also explores how accessible information and guidance can empower learners, the critical role of data infrastructure in tracking outcomes, and the unique challenges posed by the rise of digital AET. Drawing on extensive research and case studies, the report offers strategic recommendations to strengthen AET systems, ensuring they remain responsive, and aligned with the needs of both the job market and society.
