TOEFL Scores

Much of your success in graduate study in the United States depends on your ability to understand, read, write, and speak English. We require that international applicants submit scores from the Test of English as a Foreign Language (TOEFL). A limited number of applicants will qualify for waivers, but for all others, use the institution code 5156 with departmental code 99 for "any department not listed". Your score must not be more than two years old, and an official copy must be sent to the Graduate School directly from the Educational Testing Service (ETS). Personal copies are not acceptable, nor are "attested" or notarized copies.

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

We do not require a minimum score.

Name Discrepancies

We receive TOEFL scores electronically from the Educational Testing Service. 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 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 graduated with an undergraduate or a graduate degree from a U.S. college or university, where all courses were taken in the U.S.; or
  • have been working full-time in the U.S. for at least two years after receipt of undergraduate degree.

You do not need to submit anything to inform us that you are eligible; we use material from your application materials to determine your eligibility.

If you do not meet any of these qualifications but would like to inquire about the possibility of a waiver, you may request that we review your situation.

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 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. 


We do not accept IELTS scores, and the IELTS cannot be used in place of the TOEFL.
