We require international applicants to submit official test scores, unless they meet one of the waiver criteria below.

For all other students, if your native language is not English, you must submit an official score on either the Test of English as a Foreign Language (TOEFL) or the International English Language Testing System (IELTS) exam.

We do not require a minimum score.

Reporting Your Score

You must send official score reports to Duke, and they must be received prior to the deadline.

It can take several weeks for scores to arrive at schools, so you should plan to take the test or order prior scores at least one month prior to the deadline you seek.

  • Report official TOEFL scores to:

Duke University's institution code 5156 (Note: there is no department code.)

  • Mail official IELTS scores to:

Name Discrepancies

We receive TOEFL scores electronically from the Educational Testing Service and IELTS results via mail from Cambridge ESOL, British Council, and IDP: IELTS Australia. Because we match scores by an applicant's name, it is important your name on the application and your name on your test scores be the same. If it is not, you must contact us.


We offer TOEFL/IELTS waivers to those who:

  • Are citizens of any of the following countries—
    • Antigua and Barbuda

  • Have worked full-time for a minimum of two years in Australia, Canada, the United States, or the United Kingdom after receipt of undergraduate degree

Waivers based on citizenship are automatic. 

If you believe you qualify for a TOEFL waiver based on the education or work criteria, indicate this and then answer the questions in the TOEFL Waiver section of your online application that require you to state where you completed the study or work requirement. 

Due to the volume of applications we receive, we will not examine, confirm the status of, or grant any waiver requests prior to extending an offer of admission.  If your request is not granted, we will try to notify you as soon as possible to give you time to take the test.  Therefore, it is in your best interest to apply in the earliest round for each admission cycle. 

English Placement Exams

NOTE: All international students are required to take oral and written English placement exams administered at Duke during orientation. These exams are independent of the TOEFL/IELTS score submission requirement. Depending on placement results, students are either exempt from, or placed into, one English course. Students with English course requirements must make satisfactory progress toward completing these requirements while in the program.
