UC Irvine's 28.95% Rate Hides a 2x Major Spread

UC Irvine's headline acceptance rate for Fall 2025 was 28.95%, drawn straight from the campus's own Common Data Set filing (124,231 applicants, 35,964 admitted). That number is accurate and it's the one you'll see repeated everywhere. It's also an average sitting on top of real variation, because UCI doesn't evaluate one undifferentiated pool of applicants at a single rate. The UC system's own "Freshman admission by discipline" dashboard shows admit rates by broad academic category, and across six disciplines the range runs from 16.16% to 34.18%, more than double from one end to the other. A student applying with a Business intent and a student applying with an Arts & Humanities intent are, statistically, facing two different sets of odds at the same campus.

That's the part of UC Irvine's admissions data that a single headline number doesn't tell you, and it's worth unpacking before you decide how UCI fits on your list.

One more piece of context up front: the campus-wide rate has barely moved year over year. Fall 2024 admitted 28.78% of 122,706 applicants (35,317 admits); Fall 2025 admitted 28.95% of 124,231 applicants (35,964 admits). Essentially flat at the top level. That flatness is exactly why the by-discipline numbers matter: a calm headline can still sit above real movement happening underneath it, discipline by discipline, and UCI's does.

The real breakdown, by discipline

The University of California's Information Center publishes a system-wide dashboard that reports freshman admit rates by broad discipline for each UC campus. Here's every discipline UCI reports for the Fall 2025 entering class, sorted from most to least selective, with the dashboard's own displayed percentage and the raw counts behind it:

| Discipline | Fall 2025 admit rate | Raw counts (Fall 2025) | |---|---|---| | Business | 16.16% (displayed as 16%) | 2,893 admits / 17,907 applicants | | Engineering | 26.57% (displayed as 27%) | 5,387 admits / 20,276 applicants | | Computer Science | 27.58% (displayed as 28%) | 1,874 admits / 6,794 applicants | | Life Sciences | 30.29% (displayed as 30%) | 5,620 admits / 18,556 applicants | | Social Sciences | 31.63% (displayed as 32%) | 6,409 admits / 20,261 applicants | | Arts & Humanities | 34.18% (displayed as 34%) | 2,454 admits / 7,179 applicants |

Source: UC Information Center, "Freshman admission by discipline" dashboard (visualizedata.ucop.edu), Campus filter = UCI, Fall 2025. The dashboard groups majors into broad discipline categories; UC Irvine does not separately publish admit rates for individual majors, such as breaking Computer Science down into B.S. CS versus Informatics.

Read that table straight and the spread is the headline: a Business applicant this cycle was admitted at less than half the rate of an Arts & Humanities applicant, and both of them applied to "UC Irvine." Neither applied to a school with a flat 28.95% acceptance rate. Business, at 16.16%, is close to Engineering and Computer Science territory even though it doesn't carry the STEM reputation those two majors do.

Show the math

The raw counts are worth sitting with, because they show how different these applicant pools actually are in size and shape. Computer Science drew 6,794 applicants and admitted 1,874, a small, tight pool. Engineering, by contrast, drew 20,276 applicants, nearly three times as many, and admitted 5,387, landing at a similar rate to CS (26.57% versus 27.58%) despite being a much larger program. Business drew 17,907 applicants and admitted only 2,893, the fewest admits of any discipline on this list relative to its applicant pool size, which is what pins Business at the bottom of the table.

One more data point worth flagging: Fall 2024 data pulled from the same dashboard shows Computer Science admitted exactly 1,874 students both cycles, while applicants fell from 9,187 to 6,794. Holding admits flat while the applicant pool shrinks by roughly a quarter pushed CS's admit rate from 20.4% in Fall 2024 up to 27.58% in Fall 2025, a jump of nearly 7 points. That's a capacity-capped program behaving exactly like one: the number of seats didn't change, so when fewer students applied, each one who did had better odds. Business moved the opposite direction, up from 12.61% in Fall 2024 to 16.16% in Fall 2025, even as its applicant pool grew slightly, which points to Business expanding admits somewhat rather than holding a hard cap. Engineering and Life Sciences both drifted down a few points year over year, while Social Sciences and Arts & Humanities moved in different directions by smaller margins. None of these disciplines are moving in lockstep, which is itself evidence that a single campus-wide number can't represent what's happening in any one of them.

Why the spread exists

UC Irvine, like every UC campus, is test-blind: no SAT or ACT score factors into admission decisions at any UC. We cover what that means for how the rest of your application gets weighted on our test policy tracker, but the relevant point here is that removing a score-based filter tends to widen applicant pools, since students no longer self-select out of a reach major based on a test score they don't have. That alone doesn't explain why Business sits at the bottom of UCI's table, though. The more direct explanation is that Business, Engineering, and Computer Science are exactly the majors that have drawn the sharpest rise in applicant interest nationally in recent admissions cycles, while the university's capacity in those specific majors hasn't expanded at the same pace. When more students compete for a roughly fixed number of seats, the admit rate falls, and when the applicant pool eases even slightly against that same fixed capacity, as happened with UCI's Computer Science pool between Fall 2024 and Fall 2025, the rate can swing back up quickly. Arts & Humanities and Social Sciences, both larger and less capacity-constrained categories, land near the top of the table because they simply have more room relative to demand.

None of this is a guess about UCI's internal capacity planning. It's what the rate and applicant-count movements themselves show, discipline by discipline, across two consecutive cycles.

What this means for your list

The practical takeaway isn't "UC Irvine is a reach" or "UC Irvine is a safety." It's that UCI's admissions process runs six different sets of odds under one campus name, and which set applies to you depends on the discipline you list as your intended major. A student with a strong profile applying as Arts & Humanities at 34.18% is not making the same bet as a student applying as Business at 16.16%, even though both will list "University of California, Irvine" on the same UC application.

A few things follow directly from that:

• The discipline you select on your UC application is a real strategic input, not an afterthought. It sets your odds before an admissions reader evaluates anything else.
• These figures describe admission, not what happens after you enroll. UCI's own published data covers admit rates by discipline at the point of application; it says nothing about switching majors internally once you're a student, so don't treat a lower-odds major as a side door into a higher-demand one.
• Timing doesn't offer a workaround here either. UC Irvine, like every UC campus, has no Early Decision or Early Action plan, confirmed in its own Common Data Set filing. There's a single November filing period, and our application deadlines guide lays out how that period fits alongside the rest of a UC-heavy list.

If you're comparing UC campuses and want to see where your actual odds sit by discipline rather than by a single campus-wide number, our college list builder uses real admit-rate data to sort that out.

The waitlist

UC Irvine's Fall 2025 waitlist activity is worth knowing if UCI sits on your list as anything other than a clear admit. The campus offered 12,967 qualified applicants a spot on the waitlist; 5,738 accepted that spot; and 5,737 were ultimately admitted off the waitlist, per UCI's Common Data Set filing. That's a genuinely high conversion rate among students who stayed on the list, close to 100% of acceptors. The prior cycle looked similar in shape: Fall 2024 offered 13,155 waitlist spots, 6,259 accepted, and 6,259 were admitted. Both waitlist size and waitlist admits fell somewhat between Fall 2024 and Fall 2025 even as the headline admit rate held essentially flat, but in both cycles, accepting a UCI waitlist spot has functioned less like a long shot and more like a delayed admission for nearly everyone who stays on it.
