adult education, any form of learning undertaken by or provided for mature men and women. In a 1970 report, the National Institute of Adult Education (England and Wales) defined adult education as “any kind of education for people who are old enough to work, vote, fight and marry and who have completed the cycle of continuous education, [if any] commenced in childhood.” Adult education comprehends such diverse modes as independent study consciously pursued with or without the aid of libraries; broadcast programs or correspondence courses; group discussion and other “mutual aid” learning in study circles, colloquia, seminars or workshops, and residential conferences or meetings; and full- or part-time study in classes or courses in which the lecturer, teacher, or tutor has a formal leading role.
