Program Description

Graduate students desiring to work toward a Master’s degree in mathematics should have completed an undergraduate major in mathematics equivalent to the one offered by USD. Students who do not have a sufficient background in mathematics may be required to complete coursework that will not apply towards a Master’s degree (e.g., linear algebra and differential equations).

The department offers non-thesis M.A. (Plan B) and thesis and non-thesis M.S. programs (Plan A and Plan B, respectively). The M.A. supports growth and professional development for high school teachers and exposure to additional math content for people who seek employment in other fields, but do not have an interest in a terminal degree. The M.S. programs are intended for students who plan to pursue doctoral studies in mathematics and cover advanced topics that will prepare graduates to take qualifying exams in Math Ph.D. programs without the need for additional coursework.

The Graduate Mathematics Certificate is a program designed for current high school mathematics teachers who are either enrolled in or have completed a master’s degree, are interested in getting credentials to teach concurrent dual credit math courses. The 18 credit sequence of the Graduate Mathematics Certificate and Advanced Graduate Mathematics Certificate would allow them to do that.


  1. Completed Graduate Application form found at: https://www.usd.edu/graduate-school/apply-now and a non-refundable application fee of $35
  2. Official transcript(s) verifying receipt of an undergraduate degree and previous graduate credit (in English or with translation) must accompany an application. Official transcript of all academic work at the undergraduate and graduate levels are required for international students. The USD Graduate School and/or academic units retain the right to require credential evaluations from organizations, such as Educational Credential Evaluators/World Education Services (ECE/WES), for a student if such an evaluation is deemed necessary.
  3. Completion of a baccalaureate degree in Mathematics or its equivalent is required for the M.A. and M.S. programs. Completion of a baccalaureate degree in Mathematics or a related discipline is required for the graduate certificates. A minimum undergraduate cumulative GPA of 2.7 on conferred degree and/or graduate cumulative GPA of 3.0 or better, based on a 4.0 scale, on all graduate coursework is required for full admission. Each graduate program may admit students on provisional status per university policy.
  4. Applicants with degrees from countries other than the United States who have obtained an undergraduate or graduate degree from a regionally accredited American college or university are not required to submit an approved English proficiency exam score. For all other applicants, a minimum score of 79 on the Internet-Based TOEFL (iBT) or 550 on the Paper-Based TOEFL (PBT), a minimum IELTS score of 6.0, or a minimum PTE score of 53 is required for graduate admission. Applicants from or who have obtained an undergraduate or graduate degree from English-speaking countries are not required to submit an approved English proficiency exam score if their academic records after review indicate that English was the classroom language for their schoolwork.
  5. Applicants are required to submit a statement of purpose or goal statement.

Additional Program Admission Requirements:

  1. Three (3) professional letters of recommendation are required.

Subject to faculty approval, those who do not meet all of the criteria above may be admitted on a provisional basis


  • Nelontine Maxwell Larsen Award (available to graduate students majoring in the mathematical sciences)
  • Wallace Raab Memorial Scholarship (provides student memberships in the Mathematical Association of America for graduate students working toward an advanced degree in the mathematical sciences during their years of graduate study at USD. Excess earnings can be used for scholarships for selected graduate students.)
  • L. Fred and Rose E. Hart Scholarship (benefits graduate students pursuing an MS degree in mathematics, including funding research assistantship for students interested in MS Plan A [thesis] option)
