The Oceti Sakowin Education Consortium (OSEC) Special Education Program believes that all Indian children with disabilities, ages birth through 21, enrolled at member tribal schools and institutions have the right to a free and appropriate education in the least restrictive environment. OSEC strives to make this belief a reality by providing high quality technical assistance to administrative and instructional staff, and direct related services to students based upon organization member’s needs. Further, the OSEC Special Education Program serves to advise and advocate compliance with any statutes and/or regulations designed to ensure educational equity for all students with disabilities.

OSEC has an affiliation with nine tribes and schools within the state of South Dakota. These tribes include the Cheyenne River Sioux Tribe, Crow Creek Sioux Tribe, Flandreau-Santee Sioux Tribe, Lower Brule Sioux Tribe, Pine Ridge Sioux, Rosebud Sioux Tribe, Sisseton-Wahpeton Tribe, Standing Rock Sioux Tribe and the Yankton Sioux Tribe.
