Demonstrate English Proficiency, Where Required

Adequate command of spoken and written English is essential to success in graduate study at Harvard. Applicants who are non-native English speakers and who received their undergraduate degree from an academic institution where English is not the primary language of instruction must prove their English proficiency by earning either a minimum score of 100 on the Internet based test (iBT) of the Test of English as a Foreign Language (TOEFL) or a minimum score of 7.0 on the International English Language Testing System (IELTS) Academic test. Applicants who took tests more than two years ago must retake them. No test other than the iBT TOEFL or the IELTS Academic will be accepted as proof of English proficiency; a master’s degree is not accepted as proof of English proficiency.

For those students planning to submit TOEFL scores, please arrange to have an official score report sent to the Harvard University Graduate School of Arts and Sciences using code 3451. If you have a copy of your Score Confirmation Report, you can upload it to your online application for consideration by the admissions committee. However, you will still need to ensure that Educational Testing Service sends an official score report.

For those students planning to submit IELTS scores, please note that we will only accept official IELTS Academic scores submitted electronically by the IELTS test center via the E-Delivery service. Scores from the IELTS General Training module are not accepted. At the time of test-taking, please specify Harvard University Graduate School of Arts and Sciences as a score recipient. We do not accept IELTS paper Test Report Forms, nor do we verify Test Report Forms (TRFs).

Applicants unable to take the TOEFL IBT, IELTS or IELTS indicator exams may apply without these scores, and if programs recommend these applicants for admission, their admission will be provisional until they provide scores from one of the accepted tests that demonstrate the required level of English proficiency.

Financial Aid

Applicants to the HMS OGE PhD Programs should NOT complete the Statement of Financial Resources for Graduate Study. OGE PhD students receive full tuition and stipend support while they are enrolled.

Letters of Recommendation

We do not accept any paper letters of recommendation. Be sure to register your recommenders’ information in your application, as all recommendation letters must be submitted online. Paper letters of recommendation will NOT be included as part of your application.
