All international applicants whose first language is not English or who have not received baccalaureate or master's degrees from an institution in which the language of instruction is English must take the Test of English as a Second Language (TOEFL) and submit the results of that test with the application for admission. A TOEFL score of 550 on the paper test or a score of 213 on the computer-based test, or 80 points on the new Internet-based test with a minimum of 23 points on the new speaking portion; or the International English Language Testing System (IELTS) with a minimum composite score of 6.5 is required for admission.

The minimum acceptable score for the TOEFL is 550 for the paper-based test, or a total score of 80 with a 19 on the speaking section for the internet-based test (iBT). Applicants with iBT speaking scores between 15 and 18 may be considered for provisional admission, which requires completion of specified remedial English courses ESL 114G (American Oral English for Academic Purposes) and/or ESL 116G (ESL/Composition for Academic Disciplines) and attainment of a grade of B or higher. The minimum acceptable composite score for the IELTS is 6.5. Graduate programs may have more stringent requirements.
