Ault education is the practice of teaching and educating adults. This often happens in the workplace, through 'extension' or 'continuing education' courses at secondary schools, at a college or university. Other learning places include folk high schools, community colleges, and lifelong learning centers. The practice is also often referred to as 'Training and Development'. It has also been referred to as andragogy (to distinguish it from pedagogy). A difference is made between vocational education, mostly undertaken in workplaces and frequently related to upskilling, and non-formal adult education including learning skills or learning for personal development.
