Academic units UC Irvine's
academic units are referred to as schools. As of the 2023–2024
school year, there were fifteen schools and several
interdisciplinary programs. The College of Health Sciences was established in 2004, but no longer exists as a separate academic unit. On November 16, 2006, the
University of California Regents approved the establishment of the School of Law. The School of Education was established by the UC Regents in 2012. In 2016, the university announced that it had received a $40 million donation from
Bill Gross' philanthropic foundation to turn its nursing science program into the Sue and Bill Gross School of Nursing. The UC Regents formally approved the establishment of the school in January 2017. In July 2020, the UC Regents approved the establishment of the School of Pharmacy and Pharmaceutical Sciences. In July of 2024, UCI received a gift of $50 million to support the transition of the former Program in Public Health to the Joe C. Wen School of Population and Public Health, named for the donor and his family. Supplementary education programs offer accelerated or community education in the form of Summer Session and UC Irvine Extension. The academic units consist of (with their founding in parentheses): •

Admissions Undergraduate UC Irvine is categorized by
U.S. News & World Report as "most selective" for college admissions in the United States. It was the third-most selective
University of California campus for the freshman class entering in the fall of 2019, as measured by the ratio of admitted students to applicants (behind
UC Berkeley and
UCLA). UC Irvine received 124,231 applications for admission to the fall 2025 incoming freshman class and 35,964 were admitted, making UC Irvine's acceptance rate 28.94% for fall 2025. The first-year median weighted GPA was 4.19 for fall 2025. The incoming 2025 freshmen were predominantly from
Orange County (25.7%), followed by
Los Angeles County (25.3%),
San Diego County (7.3%),
Riverside County (7.0%), and
San Bernardino County (5.4%). Of the 2025 freshmen international students, a majority came from Asia. 67.0% were from
China, 6.1% from
India, 5.6% from
South Korea, 4.0% from
Taiwan, and a distant 1.9% from
Canada. Admission and yield rates also vary by the residency of applicants. For Fall 2025, California residents had a selectivity rate of 21.9% out of 86,230 applicants, with a yield rate of 25.7%. Out of state residents saw greater rate of admission, with 47.5% of 16,381 applicants receiving acceptance. However, only 5.8% of those admitted went on to enroll. Of the 21,620 international students who applied, 42.8% were accepted and 11.9% went on to enroll. That year, the most popular major for freshmen (excluding transfers) was Undeclared (15.4%), followed by Biological Sciences (12.8%), Business Administration (4.0%), Computer Science (3.9%), Public Health Sciences (3.7%), and Political Science (3.3%). The choice to offer admission is based on the University of California's comprehensive review program, which considers a candidate's personal situation, community involvement, extracurricular activities, and academic potential in addition to the traditional high school academic record, personal statement, and entrance examination scores. While residency is not a factor in admission, it is a factor in tuition expenses, with out-of-state residents fees much greater than California residents. Since the approval of
Proposition 209 in November 1996, California state law has prohibited all public universities (including UC Irvine) from practicing
affirmative action as part of their admissions processes.
Graduate In Fall 2025, The School of Law enrolled 189 out of 3,720 applicants for an enrolling class that has a median LSAT score of 169 (166-170 interquartile range), and median GPA of 3.80 (interquartile range 3.59-3.90). In Fall of 2024, the acceptance rate was 17.38%. The School of Medicine admitted 273 of 6,929 applicants for the 2024-25 academic year for an admission rate of 3.98%, placing it among the nation's 20 most selective
medical schools. Of the 273 admitted students, 114 matriculated, with an observed median GPA of 3.94 and median
MCAT score of 516 among the 2024 MS1 (first-year) class. == Discoveries and innovation ==
