From the mid-1990's until the 2007-08 school year, the National Association of Intercollegiate Athletics (NAIA) consisted of athletic regions to group certain college athletic conferences and certain independent schools that fit within the geographic footprints. With the formation of the Association of Independent Institutions (A.I.I.; now the Continental Athletic Conference) in fall 2008, the regions would be eventually dissolved.
