The School of Computer Science requires the following for all Ph.D. applications.

  • GRE scores: These must be less than five years old. The GRE Subject Test is not required, but is recommended. Our Institution Code is 2074; Department Code is 0402.
  • TOEFL scores: Required if English is not your native language. No exceptions. These scores may be more than two years old if you have pursued or are pursuing a bachelor's or graduate degree in the United States. (While the TOEFL is preferred, the IELTS test may also be submitted.) Successful applicants will have a minimum TOEFL score of 100. Our Institution Code is 4256; the Department Code is 78.
  • Official transcripts from each university you have attended, regardless of whether you received your degree there.
  • Current resume.
  • Statement of Purpose.
  • Three letters of recommendation.

In addition to the SCS guidelines, the LTI requires:

  • A short (1-3 minute) video of yourself. Tell us about you and why you want to come to CMU. This is not a required part of the application process, but it's strongly suggested. Note: applicants to the MCDS program should not submit a video with their applications.
  • Any outside funding you are receiving must be accompanied by an official award letter.

No incomplete applications will be eligible for consideration.
