Membership was generally not stable until 1969, as Madison Heights left, Highland was forced out and eventually added back into the conference, St. Mary's closed, member schools consolidated, and schools from neighboring Delaware and Hancock counties were added.
Anderson Highland was the only member who did not rejoin, as their move to the Olympic Conference caused the demise of the CAC.
Delta, another former CAC school, would take their place in the reformed conference, and divisions in football were introduced to address enrollment disparity.
This lineup would remain intact until 1995, though a massive change would happen in the next three years as five schools left.
The end of the conference began when Wes-Del left after the 2007-08 academic year to rejoin the MEC.
