In 1938,Mesa College joined the league. In 1939, the league saw its largest membership whenCarbon Junior College (later College of Eastern Utah) andSnow College joined. In the early 1940s, the league saw disruption due to the outbreak ofWorld War II – Ricks and Albion were forced to leave prior to the 1941 season, while Weber and Westminster were forced to leave prior to the 1942 season. The entire league suspended operations from 1943 to 1945. In 1946, the league resumed operations with Albion and Weber also re-joining the league. Prior to 1948, Mesa left the league, while Westminster and Ricks rejoined, and a new member also joined –Boise Junior College (later Boise College).
Following this expansion, the league would see a gradual reduction in teams. 1950 would be the final season for SICE as the school closed in 1951. Westminster left the league after the 1954 season. Weber left following the 1961 season, while Southern Utah left the following year. In 1963, Mesa returned, but Eastern Utah decided to depart the league following that season. Boise left after the 1967 season, and Mesa left after the 1974 season. The league reached its final configuration in 1979 when Eastern Utah re-joined. In 1983, member schools were Eastern Utah, Dixie, Ricks, Snow,Utah Technical College at Provo (UTCP), andColorado Northwestern Community College (CNCC).[3]
1984 would be the final season of league play for the ICAC. In 1985, theNational Junior College Athletic Association (NJCAA) realigned its regions in response to a large number ofOregon andWashington schools leaving the organization to form theNorthwest Athletic Association of Community Colleges. NJCAA Region 18 was expanded to include schools in Utah, which resulted in all ICAC members being merged into theScenic West Athletic Conference (Ricks had already been a member of the SWAC in non-football sports since 1968). For football, the league was merged with the Arizona Community College Conference to form theWestern States Football League.
