Accreditation is a voluntary process of external  review  that evaluates programs, colleges and universities to ensure they provide high-quality education and services and continuously seek to improve. This process provides assurance to the public that United Tribes Technical College (UTTC) meets, and will continue to meet, clearly communicated criteria and regulations. Accreditation also ensures faculty and students are eligible for federal grants and other funding. UTTC was granted candidacy status for accreditation by the North Central Association of Colleges and Schools in 1978. In 1982, UTTC was granted full accreditation status and has maintained continuous accreditation status since that time. The most recent comprehensive evaluation was March 31-April 1, 2025, after which UTTC's accreditation was continued as fully approved. The next reaffirmation of accreditation is scheduled for 2030-2031.

UTTC also has programs that are individually accredited by the following discipline-specific accrediting bodies:

• ASE Education Foundation: Automotive Technology AAS Degree (through 2030)
• North Dakota Education Standards and Practices Board (ND ESPB): Elementary Education BS Degree (through 2029)
