University of California San Diego Acceptance Rate
For the Fall 2025 admissions cycle (Class of 2026), UC San Diego received approximately 136,740 first-year student applications and admitted around 38,846 students, resulting in an acceptance rate of 28.4%. This marks a slight increase from the previous year and reflects the university’s continued appeal as one of the top-ranked national universities.
Despite being part of the University of California system, UC San Diego has one of the more selective admission profiles among other UC campuses, particularly for competitive majors like engineering, computer science, and biology.
As an admissions professional would note, the numbers alone don’t capture the full picture. UC San Diego’s holistic review process considers academic achievement, leadership, extracurriculars, and context—especially for out-of-state students, who face lower admit rates than in-state residents. In 2025, out-of-state applicants made up a growing portion of the applicant pool, with under 20% gaining admission on average.
UC San Diego continues to build a highly talented and diverse student body, drawing from across California, the U.S., and the globe. Its emphasis on interdisciplinary research, public service, and academic rigor makes it a strong choice for first-year students who want to thrive in a collaborative and innovative environment.
UCSD Acceptance Rate Over Time
Over recent years, the UC San Diego acceptance rate has shifted as application volume, institutional capacity, and admissions strategies evolved. Below is a summary of the most recent cycles for first‑year admission:
| Admission Cycle | Applicants | Admits | Acceptance Rate |
|---|---|---|---|
| 2020–2021 | ~100,022 | ~40,426 | ~40.4% |
| 2021–2022 | ~131,229 | ~31,102 | ~23.7% |
| 2022–2023 | ~130,835 | ~32,061 | ~24.0% |
| 2023–2024 | ~134,450 | ~35,916 | ~26.7% |
| 2024–2025 (Class of 2029) | 136,740 | 38,846 | 28.4% |
UC San Diego’s acceptance rate for the latest cycle (Fall 2025) was 28.4%, based on about 136,740 first‑year applicants and roughly 38,846 admits.
These figures show how UCSD’s competitiveness has increased since 2020, particularly as more students apply each year and as the university continues to build its national reputation.
Acceptance Rates by College at UCSD
UC San Diego consists of several undergraduate colleges, each with a distinct educational philosophy and residential community. While specific acceptance rates by individual colleges aren’t publicly reported, some programs and majors (especially in STEM fields) are generally more competitive than others. Prospective applicants should review each college’s academic focus and admissions guidance to understand specific program competitiveness.
In‑State vs. Out‑of‑State Acceptance Rates
As a public research university, UC San Diego does prioritize California residents in its admissions decisions, resulting in higher admission rates for in‑state students compared with many out‑of‑state applicants. Though exact breakdowns aren’t always published for every cycle, UCSD’s in‑state rate in recent years hovered notably above the out‑of‑state rate, reflecting the university’s commitment to serving the educational needs of Californians
UCSD vs. Other University of California Schools
Within the UC system, UC San Diego’s admissions fall into a moderately selective tier. Compared with other UC campuses in the most recent cycle:
- UCLA and UC Berkeley remain far more selective (with acceptance rates typically in the low teens).
- UC Irvine has a similar admit rate (~28–29%), slightly above UCSD.
- UC Santa Barbara reports a higher acceptance rate (~38%), and several other UCs (e.g., UC Davis, UCSC, UC Riverside, UC Merced) have progressively higher rates.
This comparison highlights UCSD’s position among its peers: a competitive, sought‑after campus that attracts strong applicants but is not as selective as the very highest‑ranked UC institutions.
What Factors Influence Acceptance Rates at UCSD?
Academic Performance
Academic excellence remains a central pillar of admissions at the University of California San Diego. For the Fall 2025 (Class of 2029) admissions cycle, competitive applicants continued to demonstrate very strong high school performance:
- The middle 50% GPA range for admitted first‑year students was approximately 4.11–4.28 (weighted UC‑capped GPA).
- This range reflects the interquartile distribution of GPAs among first‑year admits and underscores how competitive admission to UCSD has become.
These GPA figures suggest that most successful applicants are near the top of their high school class, typically earning mostly A’s in a rigorous course load that includes honors, Advanced Placement (AP), International Baccalaureate (IB), or dual‑enrollment classes.
Because UC San Diego (like all University of California campuses) uses a holistic admissions process, strong academic performance alone doesn’t guarantee admission; personal insight responses, extracurricular engagement, leadership, and unique experiences also matter.
Taking challenging courses throughout high school strengthens an applicant’s profile because it signals readiness for UCSD’s demanding academic environment and helps show you can contribute meaningfully to the campus community if admitted.

What Test Scores Are Needed for Admission to UCSD?
UC San Diego remains test-free for all undergraduate applicants. As part of the University of California systemwide policy that began in 2020, UCSD does not consider SAT or ACT scores for admissions decisions, even if submitted.
That means:
- You do not need to submit SAT or ACT scores to apply.
- Test scores, if submitted, will not be used for admissions review.
- However, scores may still be used after admission for course placement (in math or writing) or to fulfill minimum subject requirements for certain majors.
This test-free policy levels the playing field for students from different educational backgrounds and emphasizes UCSD’s holistic review approach. Your average GPA, coursework rigor, personal insight questions, and extracurriculars carry the most weight.

Essays and Recommendations
The personal insight questions (PIQs) are a vital part of the UCSD application process. These essays allow students to highlight their individuality, achievements, and aspirations. Admissions officers look for specific and personal responses, showcasing unique experiences and perspectives that are authentic to the applicant. UCSD does not require letters of recommendation for most applicants. However, specific programs or scholarships may request them, in which case recommendations can offer additional insights into an applicant’s character and potential.

Strategies to Improve Your Chances of Admission to UCSD
Build a strong academic profile
Success at the University of California San Diego begins with a strong academic foundation. Admissions officers prioritize applicants who have consistently earned high grades and excelled in rigorous coursework. This includes taking AP, IB, or honors classes, which demonstrate your readiness for the challenging academic environment at UCSD.
If your GPA is on the lower end, it’s essential to compensate by excelling in other areas, such as extracurricular activities or strong responses to the personal insight questions. Admissions officers at UCSD evaluate applications holistically, seeking students who show potential to thrive academically and contribute to the La Jolla campus community.
Write exceptional essays
The personal insight questions (PIQs) provide you with an opportunity to highlight your individuality, achievements, and aspirations. These essays are a critical part of your UCSD application and offer a platform to show the admissions team what sets you apart.
Demonstrate leadership and initiative
Leadership and initiative are key qualities that UCSD admissions officers look for in candidates. Rather than striving to be a “well-rounded” applicant with scattered activities, focus on excelling in specific areas that align with your interests and future aspirations.
Examples of leadership include:
- Founding a club or leading a project in your community.
- Excelling in fields like STEM, social sciences, or the arts.
- Taking active roles in extracurricular activities that demonstrate your ability to lead and innovate.
Expert Tip: Admissions officers are asking themselves: “How will this student contribute to campus life at UCSD? What unique qualities will they bring to the table?” Highlighting your leadership experiences and commitment to making an impact will strengthen your application because it indicates that you will be a leader and changemaker on campus in La Jolla.
