The document summarizes four organizations dedicated to lifelong learning: the Coalition of Lifelong Learning Organizations (COLLO), the American Association of Adult and Continuing Education (AAACE), the National Institute of Adult Continuing Education (NIACE), and the Council for Adult and Experiential Learning (CAEL). All four organizations are devoted to promoting and advancing lifelong learning opportunities for adults. They differ in their target populations and membership, but share a common goal of making education accessible at all stages of life through programs, advocacy, and policy work.
