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. This requirement is waived if you earned your undergraduate degree in the United States or have been working in this country for two years or more. Official TOEFL scores should be reported to Duke University’s institution code 5156; there is no department code. Official IELTS scores should be mailed to the Office of Academic and Enrollment Services, Nicholas School of the Environment, Box 90330, Durham, NC 27708. Any student whose first language is not English may be required to participate in a Skype interview to evaluate spoken English language ability. The interview results will be included in the application reviewed by the Admissions and Awards Committee. If your TOEFL or IELTS score is low, you may be accepted on the provision that you complete an intensive English language program in the United States prior to enrollment. Non-native English speakers will be required to take proficiency exams in written and spoken English during orientation week; depending on your scores, you may be required to enroll in additional English language instruction. You should be prepared to assume all costs for any required English tutoring and may need to reduce your course or research work while being tutored.
