About COSA

Preparing Today for all our Tomorrows

The Commission for Oceti Sakowin Accreditation (COSA) was established for the accreditation of schools located within tribal boundaries. We provide a consistent, reliable, and responsible accreditation service. COSA models other regional, national and international accreditation agencies and will assist qualified schools who choose to seek dual accreditation.

Cost of Accreditation

COSA is a tribal non-profit corporation. Its accreditation services are funded through dues and fees. Annual dues are collected from candidate and accredited schools and centers. Additional fees may be charged for accreditation or consultancy visits.
