English Language Proficiency Test Scores (for international applicants)

Much of your success in graduate study in the United States will rest on your ability to understand, read, write, and speak English. If English is not your first language, evidence of proficiency in its use will be a decisive factor in the application review process.

Duke University Graduate School requires that any applicant whose first language is not English submit scores from either the Test of English as a Foreign Language (TOEFL) or the academic modules of the International English Language Testing System (IELTS). Your score must not be more than two years old from July 1 of the application year. For example, if your application is submitted between August 2013 and January 2014, your score report must be dated July 1, 2011 or later.  An official copy must be sent to the Graduate School directly from the testing agency. Personal copies are not acceptable, nor are "attested" or notarized copies.

The TOEFL is administered through Educational Testing Service (ETS). Please note that ETS only reports TOEFL scores for up to two years after the test date. If you are required to submit a TOEFL score and ETS refuses to report your score, you should retake the TOEFL prior to submitting your application.

More information about the TOEFL is available on the ETS website. The TOEFL institution code number for Duke is 5156. ETS will also require you to select a departmental code, although Duke does not require it (it does not matter which departmental code you choose; Duke Graduate School will receive the scores as long as you choose institution code 5156).

The IELTS is administered by Cambridge ESOL, British Council, and IDP: IELTS Australia. More information about the test is available at Official IELTS scores should be mailed to: Office of Admissions, Duke University Graduate School, 2127 Campus Drive, Box 90065, Durham, NC 27708.  (This is both a physical location and a mailing address. If your mail service does not deliver to a PO Box, you may remove "Box 90065" from the address.)

It is the policy of the Graduate School to admit only those applicants with a minimum TOEFL score of 577 (paper-based test), 90 (internet-based test) or an IELTS score of 7.0. In many departments, a higher score may be required.

NOTE: All admitted international students whose first language is not English are required to take placement exams conducted by the English for International Students program at the beginning of the term of matriculation. Depending on the exam results, students are either exempted from or placed into EIS courses. All courses a student places into are degree requirements.  More information about the EIS program is available on the EIS website.
