National Accreditation is an evaluation service of applied science and engineering technology programs offered at educational agencies (private and public colleges, educational institutes) in Canada. It is a voluntary process whereby a program is examined and assessed for the purpose of identifying whether it meets the profession's approved standards and criteria. National Accreditation provides a third party, non-governmental auditing mechanism, independent of the educational system. A program's accreditation status is normally subject to periodic review and may be withdrawn for cause. In Canada, CTAB provides accreditation to programs only. Within CCTT, individuals are granted certification by the provincial associations.
