LTI PhD/MLT Graduate Application Support Program

This application support program aims to ensure that applicants to research graduate programs at LTI have someone to provide feedback on their application before submission. Historically, people from underrepresented backgrounds have lacked access to guidance from people familiar with the higher degree application process. In order to take steps towards an equitable application process, we invite applicants to the MLT and PhD programs to visit this page for application support through the School of Computer Science.



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

  • GREs are now optional, but if you want to submit 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.
  • If you will be studying on an F-1 or J-1 visa, and English is not a native language for you (native language…meaning spoken at home and from birth), an official copy of an English proficiency score report is required. The English proficiency requirement cannot be waived for any reason. Find more information under "Test Scores" on our FAQ page.
  • 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.
