The TOEFL is required of all applicants whose native language is not English. This requirement is waived only for applicants who will have received a baccalaureate degree, or its foreign equivalent, prior to matriculation at Yale, from a college or university where English is the primary language of instruction. If you qualify (on the basis of your answers to specific questions in the application), no waiver form is necessary. If you do not qualify for a waiver but have taken the TOEFL within the last two years you will need to have your TOEFL scores released to us (code 3987). If your scores can no longer be released, you will need to take the test. The test should be taken as early as possible to ensure that your scores are received in time to be incorporated in your file. Normally TOEFL scores will not be released if they are older then two years. If you took the TOEFL before and ETS will release those scores then you should not have to retake the examination.
International English Language Test System (IELTS). You may substitute IELTS for TOEFL.
