Big West Conference

The Big West Conference (BWC) is an American collegiate athletic conference whose member institutions participate in the National Collegiate Athletic Association's Division I. The conference was originally formed on July 1, 1969, as the Pacific Coast Athletic Association (PCAA), and in 1988 was renamed the Big West Conference. The conference stopped sponsoring college football after the 2000 season.

Among the conference's 11 member institutions, 10 are located in California (nine in Southern California alone), and one is located in Hawaii (though the Hawaii member is leaving for the Mountain West Conference, effective July 1, 2026). All of the current schools are public universities, with the California schools evenly split between the California State University and the University of California systems. In addition, one affiliate member plays two sports in the BWC not sponsored by its home conference.

The Big West Conference was formed in June 1968 as the Pacific Coast Athletic Association. The five original charter members were Fresno State, San Jose State, UC Santa Barbara, San Diego State, and Long Beach State. Two other schools, Cal State Los Angeles and the University of the Pacific, were also considered but they declined at that time to pursue membership. The newly formed conference had several meetings to set up its governance, which was confirmed in October 1968 on the campus of UC Santa Barbara. Before the league started play, Cal State Los Angeles joined as a full member and the University of the Pacific joined for football only, becoming a full member itself two years later. The conference itself lists July 1, 1969, as its founding date, with the seven institutions beginning conference play that fall.

Since its inception as the Pacific Coast Athletic Association, the conference has seen many changes. Utah State was the first institution outside California to join the conference in 1978. This opened the floodgates for many other schools to affiliate with the PCAA; notable schools include UNLV, Nevada, Louisiana Tech, Boise State, and football-only members, such as Southwestern Louisiana and Arkansas State.

In 1983, the PCAA became the first western conference to introduce women's athletic programs, allowing female student-athletes to compete at the same level as their male counterparts. This proved vital for Hawaiʻi as their only participation in the conference was for their women's sports.

However, many universities left to join conferences that were perceived as more well-known, such as the Western Athletic Conference or the Mountain West Conference, while others did not see the benefit of travel since historically many of the teams have been California-based.

From the departures of Idaho and Utah State in 2005 until the arrival of Hawaiʻi in 2012, all members were based in California, reducing the cost and travel time between the universities. When Hawaiʻi joined, it agreed to help defray a portion of travel costs to that state for the league's California members.

In 2011, San Diego State University and Boise State University had initially agreed to move all sports except football to the Big West by 2013. However, when the Big East decided to no longer sponsor football for the 2013 season, both San Diego and Boise backed out of their agreement with the Big West, electing to remain members of the Mountain West instead.
