The participating schools include Algona, Clarion, Clear Lake, Eagle Grove, Hampton, Humboldt, Iowa Falls, and Webster City.

During the 1993–94 academic year, the conference welcomed two prominent Catholic institutions: Bishop Garrigan from Algona and St. Edmond from Fort Dodge.

On December 10, 2012, the Eagle Grove Community School board voted to pursue membership in the North Iowa Conference, a decision that received approval from the NIC.

This initiative aims to maintain cohesion among the remaining eight NCC teams while also attracting nearby schools to join the league.

The NCC executive board created a transition plan to incorporate Charles City as a non-voting member, facilitating a gradual integration.

This approach is expected to enhance the conference’s collective activities and athletic programs while providing better opportunities for student-athletes.

On Monday, November 11, 2024, the school boards of Eagle Grove, Forest City, and Garner-Hayfield-Ventura voted on invitations to join the North Central Conference.

On Tuesday, November 26, 2024, during a special meeting, the Garner-Hayfield-Ventura school board revisited the invitation to join the North Central Conference.
