College Conference of Illinois and Wisconsin

The conference was formed with nine charter members (Augustana College, Carthage College, Elmhurst College, Illinois College, Illinois Wesleyan University, Lake Forest College, Millikin University, North Central College and Wheaton College) on April 26, 1946, in Jacksonville, Illinois, and opened competition in the 1946–47 academic year as the College Conference of Illinois. In 1967, the name was changed to the College Conference of Illinois and Wisconsin to recognize Carthage, which moved to Kenosha, Wisconsin in 1962, and Carroll University, which entered the conference in 1955.

The CCIW sponsors 25 sports: baseball, men's and women's basketball, women's bowling, men's and women's cross country, football, men's and women's golf, men's and women's lacrosse, men's and women's soccer, softball, men's and women's swimming, men's and women's tennis, men's and women's indoor track and field, men's and women's outdoor track and field, men's and women's volleyball and wrestling. The most recently added sports are men's volleyball, which started play in the 2020 season (2019–20 school year),[2] and bowling, which starts play in 2020–21.[3]

CCIW membership has experienced several changes since its inception. After Carthage left in 1952, Illinois College withdrew the following year (1953). Elmhurst and Wheaton withdrew following the 1959–60 academic year. Wheaton re-joined for all sports but football in 1967 (and for football in 1970). Elmhurst re-joined in the fall of 1967 for all sports but football (and for football in 1968). Carroll joined during the 1955 spring sports season (1954-55 academic season). Carthage returned in the fall of 1961, and North Park University entered the following fall (1962). Lake Forest dropped out at the end of the 1962-63 season. The last member to leave the CCIW was Carroll following the 1991–92 season. Carroll returned to the CCIW in 2016. In 2007, Rose–Hulman Institute of Technology, located in Terre Haute, Indiana, joined the CCIW as an associate member for men's and women's swimming.[4] After 2017, Rose–Hulman left as an associate member shortly before its full-time home of the Heartland Collegiate Athletic Conference announced it would add swimming.[5]

The CCIW lost one affiliate member and gained two in 2020. Greenville University, which had moved its men's volleyball program from the single-sport Midwest Collegiate Volleyball League to the CCIW in 2019–20, downgraded the sport from varsity to club status after that school year.[6] With the addition of bowling, Lakeland University, a wrestling affiliate since 2016–17, added bowling to its CCIW membership, while Aurora University and Marian University became affiliates in that sport.[3]

In 2015, men's and women's lacrosse were added as sanctioned sports by the CCIW. The CCIW announced the inclusion of men's volleyball for the 2020 season (2019–20 school year), with bowling (an NCAA sport for women only) added in 2020–21.
