NAIA independent schools

NAIA independent schools are four-year institutional members of the National Association of Intercollegiate Athletics (NAIA) that do not have formal conference affiliations. NAIA schools that are not members of any other athletic conference are members of the Continental Athletic Conference (CAC), formerly the Association of Independent Institutions (AII), which provides member services to the institution and allows members to compete in postseason competition. The CAC has one member institution in Canada's British Columbia. It provides services to the member institutions that are not fitting in any other NAIA conference and allows members to compete in postseason competition. The AII renamed itself the Continental Athletic Conference at the end of June 2021, citing the need to identify as a proper conference.
