The MSBDS and MSIBS application opens on September 1, 2020, with rolling admissions until all slots are filled. Applicants are strongly encouraged to apply early. For questions about our application process, please contact the program manager at

In addition to the online application, you will be required to submit:

  • Statement of Purpose
    Your statement should include previous professional or research experience, current professional interests, and long term career goals.

The Statement of Purpose should adequately explain these areas, but should not exceed 2 pages.

    At least two letters should be from recent academic advisors or teachers.
  • Documentation of degrees and official transcripts
    Official transcripts of all academic work at the higher education level are to be submitted in a sealed envelope sent directly by the appropriate university to the address below. Transcripts should include the grading scale. Officially transmitted electronic transcripts from an academic institution are also accepted and should be emailed to
  • Official GRE Scores

    The application for the master’s degree programs in biostatistics (MSIBS and MSBDS) normally requires the submission of official GRE scores, however, we are making this optional for the summer 2021 application to accommodate those applicants who do not have access to testing during the pandemic.

    Official GRE scores are not required, but highly recommended for summer 2021.  This is especially true for applicants with limited math/stats coursework or low GPAs in these areas.

    GRE scores will be honored if they are less than five years old.  Uploaded copies of the GRE scores are not considered official. You may attach a copy of your GRE scores to the online application, but your official GRE scores must be sent directly to Washington University.

  • Official TOEFL or IELTS Scores (preferred)
    The TOEFL or IELTS is required of international students, unless a college degree has been earned from an accredited U.S. institution of higher learning with a minimum of three years of study. If you already have notification of your score, please attach a copy with your application. The TOEFL test must have been taken within the last 2 years and the official score sent directly to Washington University (the code is 6929).
    All international students will be asked to participate in a telephone interview before a final admission decision is made. Upon arrival, all international students are tested for English proficiency by the Office of International Students and Scholars (OISS) and may be required to take English as Second-Language courses at their own expense.
  • Additional testing options for applicants applying for SU21 matriculation*:
    • Duolingo English Test – 115 minimum score
    • TOEFL ITP Plus for China (for students in Mainland China who are unable to take the standard TOEFL iBT test due to testing suspensions) – 600 minimum score (with Vericant video)
    • TOEFL iBT Home Edition – 90 minimum score
    • *AND, complete testing upon arrival within the school to determine if they need additional English courses.  If additional courses are needed, the schools must submit documentation to OISS along with the specific action plan created for the student. Tuition for additional courses is the student’s responsibility.
  • English Proficiency Standards for Admission to Washington University in St. Louis
    English Proficiency Certification for Admission and Visa Purposes
    U.S. Citizenship and Immigration Services (USCIS) requires universities admitting international students to verify that each nonnative English speaking student has sufficient English language proficiency to succeed in the academic program. Therefore, admitting departments must present proof of this level of proficiency for each nonnative English speaking student before visa eligibility documents can be processed by the Office for International Students and Scholars (OISS).Fulfilling the USCIS Requirement
    To fulfill this requirement, applicants must take the TOEFL iBT or IELTS Academic and provide an official score report showing a score at or above the following minimum levels:

    University minimum Biostatistics minimum*
    TOEFL iBT 90 100
    IELTS Academic 6.5 7.0

    For an applicant’s official test score to be valid for the purpose of English proficiency certification, the applicant must take the test less than two years before requesting that the score be reported to the university.

    *Programs With High English Communication Demands
    For programs whose students will serve as associates in instruction, do extensive reading and writing, complete a practicum or clinical experience, or otherwise meet a particularly high standard of English proficiency, departments are encouraged to establish a minimum score of 100 on the TOEFL iBT or 7 on the IELTS Academic module.

    Waiving the English Proficiency Test Requirement
    The English proficiency test requirement is waived for citizens of Australia, Cameroon, Commonwealth Caribbean nations, Ghana, India, Ireland, Kenya, Liberia, New Zealand, Nigeria, Singapore, the United Kingdom, and Zimbabwe. It is also waived for students who have completed three or more years of study in an English-medium academic program in Canada, Hong Kong, or South Africa. If a student has completed three or more years of study in an English-medium university-level academic program in a country other than the ones listed above, the department may request a waiver. In this case, the department is responsible for providing documentation to support this request (e.g., proof of appropriate minimum English proficiency standards at that university)
