Key Educational Group is a nonprofit organization whose purpose is to replicate the Key Educational model and provide centralized business/administrative support services for our network of schools based on the needs of the individual schools. We ensure educational program fidelity and support the network’s mission and vision.

Each school maintains its autonomy by having a separate school board that governs school affairs.
