Northeast Corner Conference

The five remaining schools started the conference, though Shipshewanna-Scott and Topeka were due to consolidate by 1966, while Fremont and Hamilton also participated in the State Corner Conference, while staying with their other Steuben County schools.

They joined with the Bi-County Conference teams, and changed their name to the current NECC.

Other schools to join since then were Lakeland in 1974, Fairfield in 1980, Garrett in 1981, Eastside in 1983, and Angola and Churubusco in 1989.

On January 16, 2024, it was announced that Hamilton Community High School, a founding member of the Northeast Corner Conference, would be joining the Hoosier Plains Conference in the fall of 2024.
