Frequently Asked Questions

Required Ph.D. Coursework

Please see our core class list. There are a total of 30 core course hours plus 12 hours of IE 8000 and 30 hours of electives (15 of which must be in IE), for a total of 60 hours plus 12 hours of dissertation (IE 8000). We accept a maximum of 30 transfer hours total (a maximum of 15 non-IE or IE-equivalent hours and 15 additional hours which MUST be IE equivalent) so at minimum students require an additional 30 hours of course work (10 courses) plus 12 hours of dissertation at Texas Tech. 4 of these courses must be taken over two consecutive summers (see below) and the remaining 6 can be taken at any time.

The Ph.D. program does require two summer residency terms — this means that you must be on campus for two weeks each of two consecutive summers taking courses (all of the required IE 6000 courses are taken during the summer). This is a strict requirement of the Texas Higher Education Coordinating Board and our department cannot make any exceptions to this policy. All other required courses (and sufficient elective courses) can be taken online. 


For questions concerning tuition and financial aid, you should contact student business services. They have a tuition and fees estimator you can use to estimate the cost and can also answer any questions you may have about tuition/financial aid. Brent Guinn, who manages distance education for the college of engineering, may also be able to help with questions regarding tuition for distance students.

Required Application Materials

We require all applicants to submit GRE scores (the GMAT is not considered a substitute) and transcripts from all post-secondary institutions. Three reference letters and the Departmental Questionnaire are also required. We also require proof of English proficiency for international applicants. Optional, but very strongly recommended, materials include a statement of purpose and a resume/CV. The graduate school may have some additional required materials; if so, these will be listed on their website.

A previous Master's degree is strongly recommended, but not absolutely required, for application to the program. Our department also does not require an engineering degree for the program; however we do require the following minimum background:

  • 3 hours of college level physics (with lab)
  • Calculus I, II, & III

Prospective students who apply without this background will be automatically rejected. If a prospective student who does not currently possess this background wishes to be considered for admission, the student must take any missing courses prior to applying and submit transcripts showing a grade of at least a 'C' in each course as part of their application.
We also require a course in probability and statistics at either the undergraduate or graduate level; however, students without this background will still be considered for admission, and, if admitted, will have the admission condition of a leveling course in probability and statistics. This leveling course requirement can be completed by taking either an undergraduate level course (won't count toward degree credit) or a graduate level course (will count toward degree credit).

Veterans and Military

Texas Tech has a special military and veterans program that provides specialized support for current/past service men and women and handles the process of financial aid for this population. Please see http://www.depts.ttu.edu/diversity/mvp/
