During the week of June 7, 2010, amid rumors surrounding Boise State's future in the WAC, the conference held a meeting of its athletic directors and university presidents in
Las Vegas to discuss contingency options. The conference fully expected to lose Boise State, and according to WAC commissioner
Karl Benson, there was no bitterness toward BSU by the rest of the current membership. Benson also added that the WAC was considering expanding itself, with the conference eyeing up to six current members of the second-tier
Football Championship Subdivision. Boise State left the WAC for the Mountain West at the end of the 2010–2011 season. On August 18, 2010, Nevada (Reno) and Fresno State were both extended invitations to join the Mountain West Conference, and subsequently accepted. Four months later, Hawaii also left for the Mountain West, but as a football-only member. Hawaii's other sports joined the Big West. The most dominant football member of the remaining WAC had been considering football independence. With a guaranteed bowl berth into the
Hawaii Bowl each year, the Warriors could have negotiated their own TV deal and kept all of the profits. An NCAA rule that allows any team willing to travel to Hawaii to play a 13th regular-season game (which, in practice, means an extra home game) makes it easier for the Warriors to schedule other opponents. Utah State turned down an offer from the Mountain West at the same time that Fresno State and Nevada accepted theirs, believing that the WAC schools were going to stay together and even be stronger with the possible addition of BYU. After Fresno State and Nevada accepted invitations to the Mountain West it was reported that the WAC had extended invitations to the University of North Texas and University of Louisiana at Lafayette of the Sun Belt Conference. Both schools however declined the invitations to the WAC. On September 28, 2010, the WAC heard presentations from five schools in an effort to replenish their ranks after Boise State, Fresno State, and Nevada leave for the Mountain West. The schools that made presentations were: • Three schools with FCS football programs—
Texas State University–San Marcos (which has since dropped "San Marcos" from its institutional name), a full member of the
Southland Conference; the
University of Texas at San Antonio (UTSA), a non-football member of the Southland Conference that was originally scheduled to start FCS football in that conference in 2011; and the
University of Montana from the
Big Sky Conference. All three were being considered as football members. • Two schools that do not sponsor varsity football—
Seattle University, a Division I independent, and the
University of Denver from the
Sun Belt Conference. The WAC stated at the time that they planned to issue invitations within 30 to 60 days of hearing the presentation. On November 11, the WAC announced that Denver, UTSA, and Texas State would join the WAC for the 2012–13 season for all sports (with the exception of Denver, which does not sponsor varsity football). During a September interview with WAC commissioner
Karl Benson the only school invited to a private meeting for possible expansion of teams was
Montana. However, on November 11, Montana decided to remain a
Football Championship Subdivision school in the
Big Sky Conference. On June 14, 2011, the WAC added Division I independent
Seattle University, who had been seeking membership to the WCC in the past. Exactly one month later on July 14, the WAC added
UT Arlington from the Southland Conference. On December 7, 2011, Boise State announced it would return its non-football sports to the WAC in 2013 when it begins playing football with the
Big East. Later, Boise State chose to instead place their non-football sports in the
Big West Conference, and still later due to further membership changes in the Big East, Boise State decided to stay in the Mountain West. This would have put the WAC at 11 full members, seven football and two non-football (Seattle, Denver, UT Arlington, and Boise State), one football team short of the eight required for FBS conferences. However, in the last days of April 2012, multiple media outlets indicated that six teams—three of which had not yet officially joined the conference—would shortly leave the WAC for other conferences. UTSA, which had yet to join the WAC, declared its intent to join Conference USA in 2013, with Louisiana Tech seen as likely to follow suit.
Utah State and
San Jose State declared their intent to join the Mountain West Conference in 2013. Another report indicated that Texas State and UT-Arlington, which were set to join the WAC alongside UTSA in 2012, would leave for the Sun Belt Conference effective in 2013. This would leave the WAC with only 5 full members, 2 football and 3 non-football. The first of these schools to make its departure official was Texas State, which announced its move to the Sun Belt on May 2. Two days later, Louisiana Tech and UTSA accepted invitations from C-USA, and San Jose State and Utah State announced their departure for the Mountain West. Due to the Western Athletic Conference being "raided" by the Mountain West Conference, Conference USA, and the Sun Belt Conference, it was initially unknown what path the WAC would take. After these moves, the WAC was down to only two football programs for the 2013 season –
New Mexico State University and the
University of Idaho. Since the WAC was not able to sponsor football for the 2013 season (eight teams are needed for a conference to sponsor football at the FBS level); NMSU and Idaho became
FBS independents for the 2013 season before becoming football-only members of the Sun Belt in 2014. The WAC seemingly secured its continued existence as a non-football conference, at least for the time being, when it announced on October 9, 2012, that
California State University, Bakersfield and
Utah Valley University would join the conference starting with the 2013–14 school year.
Cal State Bakersfield had previously been
independent, and had become a WAC affiliate in baseball for 2012–13.
Utah Valley joins from the
Great West Conference. Interim WAC commissioner Jeff Hurd added that the WAC was seeking to add further schools, with an immediate goal of eight members and a longer-term goal of 10. However, Hurd's job became more difficult on October 19 when Idaho announced it would move its non-football sports to the
Big Sky Conference in July 2014. In addition, Denver announced it was joining The Summit League in 2013. The WAC countered this move with inviting Division II
Grand Canyon University to join the conference, who accepted. The conference added another member from the disintegrating Great West on December 5, announcing the 2013 arrival of
Chicago State University. An invitation was also extended to the Great West's
University of Texas–Pan American, which was accepted on December 19. By adding these last Great West Conference schools the WAC was able to return to seven schools, which under current NCAA rules a Division I conference that drops below seven members must do within two years to avoid losing its automatic bids to the NCAA men's and women's basketball tournaments. ==Membership changes==
