    English Proficiency Standards for Admission to Washington University in St. Louis & Visa Issuance U.S. Citizenship and Immigration Services (USCIS) requires universities admitting international students to verify that each non-native 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 non-native 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. Duolingo will be accepted for the 2023-24 application cycle. Applicants will provide an official score report showing a score at or above the following minimum levels:

  • 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. The Duolingo English Test will be temporarily accepted for students admitted for the academic year 2024-2025 due to the pandemic. A score of 115 is the required minimum for the Duolingo English Test in order for applicants to be considered for admission. Students submitting scores from Duolingo must also complete testing upon arrival within the school to determine if they need additional English courses.

    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, Uganda, the United Kingdom, and Zimbabwe. It may also be waived for students who have completed three or more years of study in an approved English-medium academic program in any of the aforementioned countries, Canada, Hong Kong, South Africa, or the United States. 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 admitting department will need to request a waiver on a case-by-case basis. 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).
