The original name of Colorado Faculty Athletic Conference was changed to Rocky Mountain Faculty Athletic Conference (RMFAC) on May 7, 1910. The presidents assumed control of the league from the faculty in 1967 and changed the name to Rocky Mountain Athletic Conference. The Colorado Athletic Conference dissolved in 1996, with the RMAC absorbing the remaining CAC teams. The RMAC became an NCAA member in 1992 after competing in the NAIA through 1991.
