Because the University is a state-assisted institution, tuition rates are lower for Texas-resident students than for nonresidents, including both out-of-state and international students. Information about residency is given in Residency Regulations. In the following circumstances, a student who is classified as a Texas resident may be charged nonresident tuition:

Undergraduates

State law allows colleges and universities to charge a Texas-resident undergraduate the nonresident tuition rate, if the student has attempted an excessive number of hours beyond the number required for their degree. In addition, a higher tuition rate may be charged if a student enrolls again in a course they have completed.

As of the current academic year, the University does not charge undergraduates additional tuition for an excessive number of hours or for repeated courses.

Graduate students

A student who has earned more than 99 semester hours of credit at the doctoral level is subject to the nonresident tuition rate, even if the student is a Texas resident or holds an appointment that would normally entitle the holder to pay resident tuition. This policy, sometimes called the "99 hour rule," is authorized by section 54.012 of the Texas Education Code. More information about charges for excessive graduate coursework is available from the Office of Graduate Studies.

As of the current academic year, the University does not charge graduate students additional tuition for an excessive number of hours or for repeated courses.
