Undergraduate Major Codes

Last Updated: September 18, 2026 10:06:42 AM PDT

See a list of undergraduate major codes.

Important Notes:

Read about majors in TSS, different codes for the same degree, and avoiding TEA requests.
Major codes preceded by a "D" require approval of the department for admittance to the major. See Selective and Screened Majors for additional information about department approval requirements.
Historical major code information is available; look for the ISIS major code files under the Resources section.

Prospective students: See Undergraduate Majors for a list of majors and degrees.
