Can the TOEFL (or IELTS) tests be waived in certain cases for international students?
The Department will grant an automatic waiver to any student whose first language is English, any student who has been studying or working in the U.S. for two or more years, or whose undergraduate institution uses English as the language of instruction. The ETS code for sending TOEFL scores to MIT is 3514, and the code for the EECS Department is 66 (or 78). The IELTS scores are mailed by the agency directly to the MIT Admissions Office.
