Fullerton high schools ranked by UC admit rate
Share of applicants admitted to at least one UC campus, fall 2023 to fall 2025. 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. A city page ranks those schools when the city has at least 3 of them, not counting online schools, and they are not already the whole county. A rate on this page counts only the years in which UC printed both the applicants and the admits.
