The University of the Third Age is an international movement whose aims are the education and stimulation of mainly retired members of the community—those in their third ‘age’ of life. It is commonly referred to as U3A.
There is no universally accepted model for the U3A. Its original conception in France as an extramural university activity was significantly modified in the United Kingdom where it was recognized that most people of retirement age have something to contribute and the emphasis has been on sharing, without formal links to traditional universities.
Many English-speaking countries have followed this geragogic model, whereas continental European countries have mostly followed the French model.
