The Test of English as a Foreign Language (TOEFL) is required of all international applicants whose native language is not English, including those coming from English speaking colleges and universities (if in doubt about whether TOEFL is required of applicants from your country, send email to graduate.admissions@oregonstate.edu). Please also review the university requirements for language proficiency.

Students who wish to be considered for graduate teaching assistantships must meet some additional language proficiency requirements.
