===Membership timeline===

The Pac-12 claims the PCC's history as its own. Not only did it maintain the automatic bid from the Rose Bowl inherited from the PCC, but the eight largest schools in the old PCC all eventually joined the new league. However, the old PCC operated under a separate charter.

The Pac-12 is one of the founding members of the [[Mountain Pacific Sports Federation]] (MPSF), a conference organized to provide competition in non-revenue Olympic sports. All-Pac-12 members participate in at least one MPSF sport (men's and women's indoor track and field both actually have enough participating Pac-12 schools for the conference to sponsor a championship, but the Pac-12 has opted not to do so). For certain sports, the Pac-12 admits certain schools as associate members.
