CAAHEP accreditation does not expire. The accreditation process includes ongoing quality review of program compliance with the Standards, including the evaluation of information regarding program compliance form sources including, but not limited to, annual reports and progress reports. Additionally, programs are required to undergo a comprehensive evaluation, including a site visit, at least every ten years. Once accreditation is awarded, it remains in place until action is taken to withdraw accreditation, either voluntarily at the request of the program, or involuntarily based the inability of the program to comply with the Standards.
