How does admissions selectivity compare between UC San Diego and the University of San Diego?

UC San Diego is more selective than the University of San Diego for undergraduate admission, particularly for first-year applicants. UCSD draws a much larger statewide, national, and international applicant pool and enrolls students with especially strong academic records in rigorous college-preparatory coursework.

UCSD’s position in the University of California system creates exceptionally high demand, especially in STEM-related fields. Applicants are reviewed in the UC comprehensive-review process, where grades in approved courses, course rigor, academic context, and personal insight responses carry substantial weight; UC campuses do not use SAT or ACT scores in admission.

The University of San Diego is a private Catholic institution and uses a more individualized, holistic review. Strong grades and a challenging curriculum still matter, but USD also places meaningful emphasis on the student’s writing, activities, contributions to the community, and fit with its educational environment. Its applicant pool is smaller and its admissions process has more flexibility than UCSD’s high-volume public-university process.

For an applicant deciding where admission may be more attainable, UCSD should be treated as the more difficult admit, while USD may be a somewhat more realistic option for a student with a solid academic record and a well-developed application. Neither should be considered automatic, since outcomes can vary by academic preparation, residency context, intended area of study, and the strength of the overall application.
