Some of the members in the early days included Osceola, Bedford, Mount Ayr, Lamoni, Seymour, Corydon, and Leon.

Lenox and Mormon Trail of Humeston joined the conference in 1960, as Osceola departed.

This left the conference with Lamoni, Leon, Mormon Trail, Corydon, Seymour, and Moravia.

Currently, the conference hosts four of the six smallest public schools in the state, with Diagonal (26 BEDs), Orient-Macksburg (35), Moulton-Udell (38), and Mormon Trail (45).

Iowa Christian Academy officials announced on November 28, 2018, that the school would close.
