CEU is Continuing Education Unit where one CEU equals 10 PDUs. Generally, a CEU is defined as ten hours of participation in a recognized continuing education program, with qualified instruction and sponsorship. CEU records are widely used to provide evidence of completion of continuing education requirements mandated by certification bodies, professional societies, or governmental licensing boards. The records also provide employers with information on training pertinent to particular occupations.
The term CEU is in the public domain. Any organization may award a traditional CEU without requiring any accreditation. With a traditional CEU an employer or other organization must decide on an individual basis whether to honor the CEU from a training provider.
