    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).

    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 OHIDS 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.** The Duolingo English Test will be temporarily accepted for students admitted for the academic year 2022-2023 due to the pandemic.
