How the numbers are counted
Every school number is from the University of California Information Center’s Admissions by source school tables, for California public and private high schools, fall 1994 to fall 2025. A rate on this page counts only the years in which UC printed both the applicants and the admits. UC leaves a number blank when fewer than five students applied or fewer than three were admitted or enrolled, and this page does not fill a blank in. The California line adds every printed applicant and admit in the state. Any UC campus means a student admitted to at least one campus, as UC counts it. GPAs are UC’s weighted, capped GPA, not the GPA on a transcript.
A school has its own page when the University of California printed both applicants and admits for at least 3 fall terms, including at least 2 falls from 2023 to 2025, and at least 30 applicants in those window years.
