If I apply to multiple programs, do I need to submit GRE/TOEFL/IELTS scores to each department separately?
No. Test scores are matched to your application electronically based on your name; department codes do not impact this matching process.
If you submit multiple applications, each program to which you applied will have access to your official test scores, with the exception of applications to the MIT Sloan School of Management. Test scores must be submitted to MIT Sloan separately.
