Requirements

• The primary requirement for admission is evidence of intellectual achievement and potential for successful graduate study. Applicants should hold at least a bachelor's degree or its equivalent in a physical or biological science or in engineering from an institution of acceptable standing. The minimum acceptable grade point average is a "B" or its equivalent. Translation of transcripts from non-US institutions into a grading system similar to the American 4.0 point scale will help those applicants to be compared appropriately with their American counterparts.
• Beyond these minimum requirements, the admission committee looks for evidence of intellectual potential by reviewing performance in university coursework, considering GRE/TOEFL scores, and carefully reading the candidate's statement of interest and letters of recommendation. The candidate's statement and recommendation letters should highlight the applicant's potential for performing independent, thoughtful research. That can be done, for example, by describing the candidate's previous research experience in an academic or industrial setting, or by describing the student's ability to think beyond class assignments in a coursework setting. The candidate's statement should include a description of the student's future research interests, as well as their motivation for pursuing graduate education.
• Three letters are required. Once you have identified recommenders in your application, they will be sent a secure online submission link. Letters of recommendation will only be accepted via the online system. No paper letters will be accepted.
• Transcripts: UC Davis requires academic records from each college-level institution you have attended. You will be instructed to upload scanned copies of your transcripts after you have submitted your online application. 
• Application fees are currently $90.00 for domestic applications and $110.00 for international applications.
• All applicants are required to take the General Graduate Record Examination (GRE). Scores must not be more than five (5) years old. Scores must be reported electronically to UC Davis. We strongly recommend that you plan to take your GRE examination early in order for scores to arrive prior to the deadline. There is no minimum requirement.
• For the Test of English as a Foreign Language (TOEFL) Exam, a minimum score of 80 is required. Students with TOEFL iBT scores of 104 or below will be required to take an additional ESL examination once they start their graduate program here to determine their level of English ability and whether they would benefit from additional ESL coursework at UC Davis. Students with a TOEFL Speaking section scores less than 23 will also be required to take and pass the UC Davis SPEAK test in order to be eligible to serve as a Teaching Assistant.
• The International English Language Testing System (IELTS) Exam - as an alternative to the TOEFL, you may submit scores from the Academic Modules of the International English Language Testing System (IELTS) designed by the University of Cambridge Local Examinations Syndicate and administered by the British Council worldwide. You are responsible for providing Graduate Studies with an official test report form showing the score you earned on your IELTS examination. Remember to order the TRF when you register to take the test. The minimum score required for admission to graduate study at UC Davis is 7 on a 9-point scale
