What does “in education” mean?

As a general rule, a young person is considered to be in education when they regularly attend a recognised academic/training programme (minimum of 4 weeks) which takes up most of their time (a minimum of 20 hours a week spent on: school-based lessons, homework, preparation and revision, courses, conferences, dissertation research and writing, distance learning, etc.). This education should lead to a vocational diploma or the acquisition of a general education which in turn will facilitate the acquisition of assorted professions and occupations.
