TOEFL scores— All international applicants whose native language is not English must submit a TOEFL score. There are some exemptions to this requirement, for instance, if you have attended a university in an English-speaking country for two years or more. All applicants must submit a TOEFL score of at least 590 (paper-based), 243 (computer-based), or 97 (iBT). Applicants with TOEFL scores below these numbers cannot be considered for admission. TOEFL scores below 610 (paper-based), 253 (computer-based), or 103 (iBT) indicate the need for further English study. This consists of enrollment in English as a Second Language (ESL) courses based on an English Placement Test (EPT) taken upon arrival at the University. The University of Illinois now accepts IELTS scores in place of TOEFL.

Applicants with scores below a 6.5 overall or below a 6.0 on any subsection cannot be considered for admission. Students who score below a 7.0 overall will need to enroll in ESL courses based on an an English Placement Test.

These scores must be submitted through ETS, the company that administers the GRE. The institution code for the University of Illinois is 1836. For the department code, use "00" or "0000". (ETS records are held by the central administration, so no department code is required.) GRE scores of successful applicants typically are in the 80th percentile or above.

A GRE subject test is not required.
