Frequently Asked Questions

Check also the Graduate College FAQs at:


  1. What is the minimum GRE score to be accepted?
    The general GRE is required and the subject (Physics) test is strongly recommended. There is no minimum requirement for acceptance, but assistantships will be offered to candidates selected based on all application documents.
  2. What is the minimum TOEFL or IELTS score to be accepted?
    If English is not your first language, an official TOEFL score of 90 (internet based test) or IELTS score of 7.0 (overall band score) is needed to satisfy English proficiency requirements. Outstanding applicants with official TOEFL scores of 79-90 or IELTS scores of 6.5-7.0 will also be considered for admission into the graduate programs.
  3. Are you accepting applications for Spring admission?
    We will be accepting applications only for Fall (August) admission.
  4. What is OSU's GRE institution code?
    OSU's GRE institution code is 6546. We recommend a department major field code of 0899 (Physics and Astronomy - Other).
  5. What is OSU's TOEFL institution code?
    The TOEFL institution code for OSU is 6546. We recommend a department code of 76 (Physics).
  6. Can previous graduate credit be transferred?
    The degree requirements specified on this website are for M.S. students entering with no previous graduate credit and for Ph.D. students entering with no previous graduate credit or no previous graduate credit beyond the M.S. In other cases, some adjustment of the degree requirements may be possible; all adjustments are subject to approval by the Department and by the Graduate College. For example, a M.S. student may transfer up to 9 credit hours of coursework completed elsewhere, provided those courses did not count toward a previous graduate degree. The same rule applies to Ph.D. students, but there are other considerations for Ph.D. students, some of which are listed below. A Ph.D. student who has completed an approved M.S. degree elsewhere enters the 60-hour Ph.D. program; completion of the M.S. allows reduction of the credit hour requirement from 90 hours to 60. Ph.D. students in either the 90-hour or 60-hour program with previous graduate credit may be able to transfer more than 9 credit hours of the 30-hour coursework requirement, provided the courses were not counted toward a previous degree, and were taken in a department that offered the Ph.D. In general, however, coursework amounting to at least one-fourth of the program hours must be completed at Oklahoma State University (23 hours for the 90-hour Ph.D, 15 for the 60-hour Ph.D.). Some very special circumstances, such as students following their Ph.D. advisor to his/her new faculty position at OSU, might allow for further consideration, but in any case a minimum of 30 credit hours must be completed at OSU.
