Full Member Schools and Sports Sponsorship
Each full member supports a broad slate of sports, though the exact number of teams in the Pac-12 varies by sport due to affiliate arrangements. The core schools provide the foundation for league identity and championships.
Current full members include the University of Arizona, Arizona State University, Stanford University, UCLA, University of California Berkeley, and the University of Oregon. These schools field the majority of teams counted in official Pac-12 standings and championship events.
Affiliate Members and Sport-Specific Lineups
Affiliate membership allows the Pac-12 to retain brand relevance in sports where it does not sponsor full programs. These partnerships expand the number of teams in the Pac-12 on a sport-by-sport basis without full conference alignment.
For example, certain schools participate in Pac-12 women's soccer or beach volleyball while competing in other conferences for football or basketball. This hybrid model influences how fans and media interpret total league membership.

- Verify sport-specific affiliations each season, as they can shift with conference strategy.
