Frequently,
in the United States, continuing education involves enrollment in
college/university credit-granting courses, often by students
enrolled part-time, and often offered through a division or school of
continuing education of a college/university known sometimes as the
university
extension or extension school.
Also frequently in the US, it can mean enrollment in
non-credit-granting courses, often taken for personal, non-vocational
enrichment (although many non-credit courses can also have a
vocational function). Also, in the US, many such non-credit courses
are offered by community colleges.
