Application Deadlines

Application review begins in January and most Graduate Teaching Assistantships are awarded by March 15th. Applications past these dates will be considered on a "space available basis".

If your ultimate goal is the PhD program in Statistics, you must first apply for the MS program in Statistics.  Upon successfully passing the PhD qualifying qualifying exam, a student can then formally enter the PhD program in Statistics.

** Note Incomplete applications cannot be considered

Optional Tests

The Graduate Record Examination (GRE) is not required for the Statistics program, however it can help strengthen an application. These scores must be received directly from ETS. Verbal GRE scores for program applicants should be no lower than 152 for all applicants including International applicants. The institution code for Montana State University is 4488.

International Applicants

In addition to the above, International applicants must also provide:

--English proficiency scores with the following minimums: TOEFL (80; a score of 93 to qualify for a Graduate Teaching Assistantship), IELTS (level 7), or PTE (61), are required for applicants who are not U.S. citizens and are not from countries where English is the official language. This requirement is waived if the applicant has earned an undergraduate or graduate degree from an institution in the U.S. or if the student is from a country where the English proficiency score is waived. Please see the following link for countries where the examination is waived:
-- Evidence of financial support
-- Proof of funds (if self-funded)
-- Copy of applicant’s passport
-- Degree certificates as well as an English translation for all non-English academic transcripts and credentials. Photocopies can be used to initiate the application process, however official transcripts/credentials are still required upon admission.

Please see our International application process page for more information.

For additional required admission documents please see program website or view list of requirements in the graduate application portal.


The Department of Mathematical Sciences offers a wide range of technical and research degrees and is a recognized leader of research in the mathematical sciences. Much of the research is conducted in collaboration with various science departments, university centers, and collaborators worldwide. The department conducts research in both pure and applied mathematics with emphases in dynamical systems theory, mathematical biology and applied and computational mathematics. Joint research also involves engineering and the biological sciences. Statistics research encompasses a broad range of theoretical and applied topics with several interdisciplinary opportunities including the environmental and ecological sciences. Mathematics education research takes an applied approach, addressing issues that surround mathematics teaching and learning with a focus on the development and ongoing support of K-12 mathematics teachers. Active research venues include content courses and field experiences for pre-service teachers, students and teachers in K-12 classrooms, professional development for in-service teachers, and online learning environments. The department provides unique opportunities for innovative instruction and cooperative research. With approximately 26 Ph.D. faculty and around 70 graduate students, the department is large enough to attract and retain the most capable faculty, but small enough to allow faculty and graduate students an intimate atmosphere for the easy exchange of ideas.
