One year later, Washington State College (now Washington State University) joined the league, followed by Stanford University in 1918.

In 1922, the PCC expanded to eight teams with the admission of [[USC Trojans|USC]] and [[Idaho Vandals|Idaho]]. [[Montana Grizzlies and Lady Griz|Montana]] joined the Conference in 1924, and in 1928, the PCC grew to 10 members with the addition of [[UCLA]].

For many years, the conference split into two divisions for basketball and baseball—a Southern Division comprising the four California schools and a Northern Division comprising the six schools in the [[Pacific Northwest]].

In [[1950 college football season|1950]], Montana departed to join the [[Mountain States Conference]]. The PCC continued as a nine-team league through June 1959.
