Requirements

The School of Computer Science requires the following for all Ph.D. applications. (Please note, these requirements may change for future application cycles.)

• GRE scores: GREs are now optional. If you want to submit GRE scores, they 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.
• For more details on these requirements, please see the SCS Doctoral Admissions page.

• Any outside funding you are receiving must be accompanied by an official award letter.
• Video Essay (optional, but strongly recommended). You will have 1-3 minutes to record a video of yourself answering a question that we will provide. You will first be able to complete a test video, which will give you instructions and allow you to practice how the recording will work. You can complete more than one test video. Once you are satisfied and have confirmed that you're ready to record your real submission, you will receive a random question and will have 10 (ten) seconds before the video begins recording. You then have up to 3 minutes to speak and can stop recording once you are done speaking. You will be given 3 attempts, and a new question will be provided with each attempt.
  
  Note that the video (and audio) must be of the applicant (not a proxy). If there is more than one person in the video, please clarify which person is the applicant. What you do or say is totally up to you as long as you provide the information requested.
  
  If all else is equal, an applicant with a video essay will have an advantage over an otherwise identical applicant without a video essay.
  
  Again, this is not a required part of the application process, but it's strongly suggested.
