English Language Proficiency Test Scores

If your first language is not English, you must 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). In response to the temporary closings of testing centers in countries affected by the COVID-19 pandemic, we will also accept Duolingo English Test examination results for the 2020-2021 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. While average test scores are above the levels listed below, we generally seek scores no less than:

  • 577 for paper-based TOEFL
  • 90 for an Internet-based TOEFL
  • 7.0 for the IELTS
  • 115 for the Duolingo English Test

Reporting Your Score

Enter institution code C621 (Duke Kunshan U-MS of ECE- Graduate Organization.)

Duke University Graduate School
Graduate Office of Admission
2127 Campus Drive
Durham, NC 27708

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” 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.

You will also need to upload an electronic copy of TOEFL or IELTS or Duolingo score report in the application system to the ‘IELTS score report’ folder.
