The North Dakota College Athletic Conference (NDCAC) was a collegiate athletic conference that ceased operations following the 1999–2000 academic school year when it merged with the South Dakota Intercollegiate Conference to form the Dakota Athletic Conference. The former NAIA conference originally started as the Interstate Athletic Conference in 1922, with five North Dakota schools and Moorhead State Teachers College from Minnesota. Moorhead State left in 1931 to help found the Northern State Teachers Conference in 1931, and the remaining members brought in more schools to regroup as the NDCAC.[1]
