The conference began with 12 schools, though had turnover within its first year, mainly having to do with gym issues.
Williamsburg, on the other hand, had the opposite problem; its gym was found to be too small for conference play, and moved them out as well.
To fill their spots, the conference recruited Milroy, Morristown, and Morton Memorial to join the fold.
The formation of the TEC in 1962 almost caused the ECC to fold, as it was left with five members.
The sole remaining member, Morton Memorial, opted to join the BBRC that next year.
