A major shakeup occurred in 1958, as Portage and Chesterton grew too large for the other remaining schools and left.

For the 1975–1976 school year, La Crosse (renamed Tri-Township in 2022) and Westville joined the PCC.

Westville left the PCC after the 1997–1998 school year for the Northland Athletic Conference (now defunct).

Hanover Central announced in 2012 that it would leave the PCC in to join the Greater South Shore Conference.

The PCC allowed Hanover Central to leave a year early in 2013, and voted to readmit Westville, who had been an independent since the demise of the Northland Conference.
