Generally, vocation and career are used interchangeably. Vocational education might be
classified as teaching procedural knowledge. This may be contrasted with declarative
knowledge, as used in education in a usually broader scientific field, which might
concentrate on theory and abstract conceptual knowledge, characteristic of tertiary
education.
Vocational education can be at the secondary or post-secondary level and can interact with
the apprenticeship system. Increasingly, vocational education can be recognised in terms of
recognition of prior learning and partial academic credit towards tertiary education (e.g., at a
university) as credit; however, it is rarely considered in its own form to fall under the
traditional definition of a higher education.
