The UCF varsity athletic program was a charter member of the Sunshine State Conference in 1975. The school moved up to Division I in 1984. In its first years in D-I, UCF was a member of the American South Conference, merging into the Sun Belt Conference in 1991. Women's sports in Division I played in the New South Women's Athletic Conference until 1990, when the American South began organizing women's sports. In 1992, UCF joined the Trans America Athletic Conference (TAAC) in all D-I sports except football, which remained independent. In 1996, UCF was advanced to I-A (FBS) in football, and initially remained independent in football until becoming a football-only member of the Mid-American Conference in 2001, the same year the TAAC became the Atlantic Sun Conference (ASUN). UCF joined Conference USA (C-USA) in all sports in 2005, and the American Athletic Conference (The American) in 2013.
