English Language Testing (International Applicant only)

International applicants must submit official test scores unless eligible for a waiver

In response to the temporary closings of testing centers in countries affected by the COVID-19 pandemic, Duke's MEng program  will also accept Duolingo English Test examination results for the 2022 application cycle as an alternative to TOEFL and IELTS examinations. Only Duolingo English Test scores with subscores will be accepted. If you took the test prior to July 15, 2019, you will need to retake the test to comply with the subscores requirement.

Due to the current pandemic, Duke will accept Duolingo English Test examinations results for the 2023 application cycle only.

As an international student, much of your success in graduate study in the United States depends on your ability to understand, read, write, and speak English.

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), the International English Language Testing System (IELTS) exam, or Duolingo with subscores.

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.)

  • Report official IELTS scores to:

Duke University Pratt School of Engineering

  • Report official Duolingo scores:

There is no institutional code for Duolingo, but applicants will need to select “Duke University Graduate Programs: Graduate School; Divinity; Engineering; Environment; Public Policy; Duke Kunshan” at the "Graduate" program type level as the institution to send scores to. Please Note: Make sure to include subscores when you select your institution. Score reports without subscores will not be accepted. If you are not sure how to include subscores in your score report, please contact Duolingo English Test support on the Duolingo English Test website.

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
    • Australia
    • Bahamas
    • Barbados
    • Bermuda
    • Canada
    • Grenada
    • Guyana
    • Ireland
    • Jamaica
    • New Zealand
    • Saint Kitts and Nevis
    • Saint Vincent and the Grenadines
    • Singapore
    • Trinidad and Tobago
    • the United Kingdom
  • Have studied fulltime for two years or more at a college or university where the sole language of instruction is English and in a country where English is the primary spoken language. The two years of study must be completed prior to the start of the program, or
  • Have earned an undergraduate degree at Duke Kunshan University (DKU), or
  • 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

English Placement Exams: All international students may be required to take oral and written English placement exams administered at Duke prior to the start of classes. These exams are independent of the TOEFL/IELTS/Duolingo score submission requirement. Depending on placement results, students are either exempt from, or placed into, English course(s). Students with English course requirements must make satisfactory progress toward completing these requirements while in the program.
