Conference and program changes

 * It was the first season for the Mountain East Conference, a league founded by eight schools that announced in June 2012 that they would leave the West Virginia Intercollegiate Athletic Conference (WVIAC)—a move that led to the demise of the WVIAC. These eight schools were soon joined by three other football-playing schools, plus one non-football WVIAC member that had been left out of the original split.

Black Hills State, Lindenwood, Malone, McKendree, South Dakota Mines, and Walsh completed their transitions to Division II and became eligible for the postseason.
