The University of California (UC) system has a unified application deadline for undergraduate admissions. The application period opens on August 1, and the submission deadline is November 30 for fall admission the following year. Late applications are not accepted.
For graduate programs, deadlines vary by department and campus. Most fall deadlines range from December to March, but applicants should verify specific dates on the UC website or with the respective department. Some programs may accept winter or spring applications, though these are less common.
Prospective students should also check for supplemental material deadlines, such as transcripts or test scores, which may differ.
