Western Collegiate Hockey Association

On March 22, 2011, Minnesota and Wisconsin announced that their men's teams planned to leave the league in order to form a hockey Big Ten Conference in 2013–14, along with Penn State, which would start a varsity hockey program in 2012–13, and Central Collegiate Hockey Association members Michigan, Michigan State, and Ohio State.[8]

In response to the creation of the Big Ten men's hockey conference, Denver, Colorado College, North Dakota, Nebraska-Omaha, Minnesota-Duluth, and St. Cloud State left the WCHA to join Miami University and Western Michigan of the CCHA to create the National Collegiate Hockey Conference.[9][10] Facing membership at 4 teams for the 2013–14 season, the WCHA conference added one of its former members, Northern Michigan of the CCHA, on July 15, 2011.[11]

On August 25, 2011, the WCHA announced that it had invited the University of Alaska Fairbanks, Bowling Green, Ferris State, and Lake Superior State to join beginning in the 2013–14 season. On August 26, 2011, Alaska-Fairbanks, Ferris State, and Lake Superior State accepted their invitations and joined Northern Michigan in the WCHA in 2013.[12] After much deliberation, on October 4, 2011, Bowling Green decided to join the WCHA as well in 2013.[13] On January 17, 2013, the WCHA admitted Alabama–Huntsville to the league, effective in the 2013–14 season.[14]

This realignment activity only affected the men's side of the WCHA. Even after Penn State took the ice with both men's and women's teams, the Big Ten still had only four members with varsity women's hockey (Michigan and Michigan State field only men's teams). This meant that the women's side of the WCHA remained intact for the immediate future.

The next change in the conference membership came shortly after the 2016–17 season, when North Dakota announced that it would drop women's hockey.[15]

During the 2019 offseason, the future of the men's side of the WCHA fell into serious doubt when its seven Midwestern members—Bemidji State, Bowling Green, Ferris State, Lake Superior State, Michigan Tech, Minnesota State, and Northern Michigan—notified the WCHA that they would leave the league after the 2020–21 season, potentially forming a new men's hockey conference.[16] In February 2020, these seven schools announced they would form a new CCHA.[17]

At the time the seven Midwestern members announced their plans to leave, the two Alaska teams were facing a crisis following the veto by state governor Mike Dunleavy of over $100 million in funding for the University of Alaska system, a move that was seen as potentially ending intercollegiate athletics entirely at both the Anchorage and Fairbanks campuses.[18] The cuts led the UA system to start the process of consolidating the three-campus system into a single accredited institution (though retaining the existing campuses), with the system president telling local media that a single accreditation would likely lead to the Anchorage and Fairbanks athletic programs being combined into a single program. While both campuses continued to sponsor men's ice hockey in the 2019–20 season, the future of at least one of the teams beyond that point was then seen as uncertain at best.[19] Later developments saw many of the budget cuts pulled back, as well as a temporary halt to work on a single UA system accreditation; this led the UA system to announce that athletics at both campuses would continue as is through the 2020–21 school year.[20]

In November 2019, Alabama–Huntsville submitted a withdrawal letter to the WCHA, stating that it also planned to leave after the 2020–21 season. At the time, UAH was discussing potential future options with the two Alaska campuses.[21] However, UAH subsequently dropped hockey effective immediately on May 22, 2020 due to the financial impacts from the COVID-19 pandemic on its athletic department [22] On May 29, 2020 UAH President Darren Dawson announced that men's hockey would return for the 2020–21 season after more than $750,000 in private contributions were made during the week prior.[23]

In August 2020, Alaska Anchorage announced that it would drop hockey after the 2020–21 season.[24] The University of Alaska Board of Regents offered the hockey team a chance at reinstatement in September if they could raise 2 seasons worth of expenses, approximately $3 million by February 2021. The fundraising was divided into 2 parts: $1.5 million in cash and the remainder in firm pledges. As of December 2020, the team has begun fundraising for the needed money.[25]

While the men's WCHA is now all but certain to fold, the women's WCHA announced a further expansion effective in 2021–22 with the arrival of St. Thomas, a Twin Cities school that received NCAA approval to directly transition from Division III to Division I. St. Thomas had been expelled from its longtime D-III home of the Minnesota Intercollegiate Athletic Conference effective with the end of the 2020–21 school year due to perceptions by many members that it had grown too strong for that conference in multiple sports.[26][27] The Summit League offered the Tommies a D-I home, and backed the school's bid to directly transition from D-III.[28]
