Tribal schools in the United States include tribally controlled grant and contract schools, Bureau of Indian Education (BIE) funded institutions, and tribal colleges and universities (TCUs) dedicated to preserving indigenous languages and cultures while providing rigorous academic programs. Notable examples include Diné College, Oglala Lakota College, Haskell Indian Nations University, and numerous K-12 reservation-based tribal day and boarding schools across states like Arizona, South Dakota, and New Mexico.
