A look at six years of application, admission, and enrollment data from 105 California colleges reveals a clear pattern: demand for CSUs has flat-lined while every other type of institution has grown. Here’s what the numbers show — and what enrollment leaders should be thinking about.

Data: IPEDS & institutional reporting, 2018 vs. 2024  ·  105 California institutions

Imagine two grocery stores side by side. One of them keeps lowering its prices and putting more items on the shelves. The other raises prices slightly but always seems to have a line out the door. Which one is actually more popular?

That’s roughly the situation the California State University system finds itself in right now. Between 2018 and 2024, CSUs made it dramatically easier to get admitted — the average campus went from accepting about 6 in 10 applicants to accepting nearly 9 in 10. And yet the number of students applying to CSUs barely budged. Meanwhile, the UC system, private colleges, and even small non-profit institutions all saw meaningful jumps in applications.

This post walks through what I found when I analyzed data from 105 California colleges, looking at three things: how many students are applying, how selective institutions are being, and most importantly, how many admitted students actually choose to enroll.

Part 1: Who Is Actually Getting More Applications?

Let’s start with the most basic question in enrollment: are students interested?

I compared application numbers from 2018 to 2024 across four types of California institutions — CSUs, UCs, private non-profits, and for-profit colleges. The differences are striking.

+2.4% CSU system 637K → 686K apps

+28% UC system 697K → 898K apps

+42% Private non-profits 355K → 419K apps

Let’s put those numbers in human terms. In 2018, the UC system and the CSU system received almost the same total number of applications — about 637,000 for CSUs and 697,000 for UCs. Six years later, the UC system is receiving nearly 900,000 applications a year. The CSU system? Just 686,000 — barely different from where it started.

Private non-profit colleges — many of them smaller schools without the brand recognition of UCs — grew their applicant pools by 42%. Even a 28% increase at the UCs, driven by every single campus growing, dwarfs what the CSU system managed.

What “not statistically significant” means in plain English: When we say the CSU’s 2.4% application growth is “not statistically significant,” we mean: given the variation between campuses, we can’t confidently say this is a real trend rather than random noise. Some campuses grew a lot; others shrank. The net result is essentially flat — we’d expect to see this kind of scatter even if nothing was actually changing. For the UC system’s +28% growth, we can say with high confidence it’s a real trend, not a fluke.

There is one caveat worth noting. The CSU system is not uniform. A handful of campuses, including San Diego State and Cal Poly Pomona, saw genuine application growth. But others, including San Francisco State, Cal State LA, and Sonoma State, lost applicants. The system-wide number flat-lines because gains and losses roughly cancel each other out.

Part 2: CSUs Are Admitting Almost Everyone. Is That Working?

One response to flat application numbers is to cast a wider net — admit more of the students who do apply. That appears to be what has happened across the CSU system on a massive scale.

In 2018, the average CSU campus accepted about 60% of applicants. By 2024, that figure had risen to 86%. Several individual campuses — including CSU-Monterey Bay, CSU-Stanislaus, and Cal Poly Humboldt — are now admitting 97 or 98% of applicants. That is, functionally, open admissions.

For context, the UC system’s average acceptance rate in 2024 was 43%. Private non-profits averaged 60%. So CSUs are admitting students at roughly twice the rate of UCs.

This is a real and deliberate policy shift — and it has a legitimate purpose. The CSU system has an explicit equity and access mission. Opening admissions to more California students, especially those from underrepresented communities, is a meaningful goal. The concern raised by this data isn’t that CSUs are admitting more students — it’s that the strategy doesn’t appear to be translating into more students actually enrolling.

The critical question is whether easier admission translates into more students enrolled. The answer appears to be: not really. And that brings us to the most telling number in this entire analysis.

Part 3: The Yield Rate — The Number That Actually Matters

Yield rate is the percentage of admitted students who choose to enroll. It’s the most honest measure of whether students genuinely want to attend your institution — not just whether they applied or got in, but whether they said yes when you said yes to them.

Institution type	Yield rate (2024)	What it suggests
For-profit colleges	61%	High — students choose these intentionally
Private non-profits	31%	Strong first-choice preference
UC system	22%	Selective; still meaningful preference
CSU system	13%	Lowest of all groups — by far

Think about what a 13% yield rate means in practice. For every 100 students a CSU campus admits, about 87 of them choose to go somewhere else instead. The CSU got their application. The CSU said yes. The student still said no.

The difference between CSUs and non-profits (13% vs. 31%) is statistically significant — meaning we can be confident this is a real gap, not just random variation. And it holds up whether you look at individual campuses or the system as a whole.

The “safety school” effect A low yield rate is the mathematical fingerprint of being a backup option. Students apply to CSUs, get admitted, and then enroll somewhere they preferred more — a UC, a non-profit, an out-of-state school. This isn’t a problem with any individual campus’s financial aid packaging or marketing. It reflects how students perceive the entire system relative to their alternatives.

One more pattern worth noting: when you map admission rate against yield for each campus, CSUs and UCs cluster in completely different places. CSU campuses tend to admit nearly everyone and enroll very few. UC campuses admit fewer students but a larger share of those admitted choose to attend. This is a system-level positioning gap, not a campus-level problem.

Part 4: Three Questions Enrollment Leaders Should Be Asking

This data doesn’t point to a single cause, and it doesn’t prescribe a single fix. But it does raise questions that the CSU system — and any institution watching these trends — should be grappling with.

• If we admit 90% of applicants but only 13% enroll, what does that tell us about why students applied in the first place? Are we a destination or a fallback?
• The UC system grew applications by 28% and private colleges by 42%. CSUs grew by 2.4%. That gap is too consistent to be coincidence. What is driving student preference toward other institutions?
• Lowering admission standards hasn’t moved the needle on applications or yield. If anything, there’s a risk that high acceptance rates reinforce the “safety school” image that drives low yield in the first place. Is near-open admissions helping or hurting the brand?
