To ensure continued academic excellence, accreditation requires periodic institutional and program self-assessment and review. Each accreditor sets its own accreditation cycle (i.e., periods of review). Accreditation is a rigorous process that includes an institutional or programmatic self-study, a review conducted by a team selected by the accrediting body, an accreditor staff review, an academic review committee, and, finally, the board of the accrediting body. The process can take many months before final board approval. In addition to reaffirmation of accreditation, an institution may also have to submit a substantive change request when asking for expanded degree granting authority (e.g., new programs). Together, these processes assure academic quality to students, the general public, and employers.
