In the United States, tribal colleges and universities (TCUs) are a category of higher education, minority-serving institutions defined in the Higher Education Act of 1965. Each qualifies for funding under the Tribally Controlled Colleges and Universities Assistance Act of 1978 (25 U.S.C. 1801 et seq.) or the Navajo Community College Act (25 U.S.C. 640a note); or is cited in section 532 of the Equity in Educational Land-Grant Status Act of 1994 (7 U.S.C. 301 note). These educational institutions are distinguished by being controlled and operated by federally recognized American Indian tribes; they have become part of American Indians' institution-building in order to pass on their own cultures. The first was founded by the Navajo Nation in 1968 in Arizona, and several others were established in the 1970s. As of 1994, they have been authorized by Congress as land-grant colleges. As of 2018, there are 32 fully accredited Tribal Colleges and Universities (TCUs) in the United States, with one formal candidate for accreditation. History The Tribal College movement developed as part of the Native American "self-determination" movement of the 1960s. Federally recognized tribes wanted to have more control over the education of their children and ways to pass on their culture, and develop contemporary skills to build economic capacity. They have developed tribal colleges on or near Indian reservations. These provide access to post-secondary education, accredited degrees, and vocational training for both Indian and non-Indian students in many rural areas. The first tribal college was Navajo Community College, now called Diné College, founded on the reservation in Tsaile, Arizona, in 1968. It was accredited in 1979. Tensions immediately arose between advocates of two philosophies: one that the tribal colleges should have the same criteria, curriculum, and procedures for educational quality as mainstream colleges, and the other that the faculty and curriculum should be closely adapted to the particular historical culture of a tribe. Faculty and staff had a high rate of turnover, exacerbated by very tight budgets. Several other tribal colleges were established in the 1970s, and enrollment at such institutions has steadily increased. Since the 1970s, when many of these colleges were founded, most tribes have developed curricula that incorporate their Native culture and tradition. These institutions are generally located on reservations and face problems similar to those of other rural educational institutions: recruitment and retention of students and faculty because of relative isolation (in some cases quite strong) and
