What Is UCSD’s Waitlist Acceptance Rate?

For the Class of 2028, UCSD gave waitlist spots to 27,521 students. Out of those, 19,156 chose to stick around, but only 4,539 students were ultimately admitted. So, the UCSD waitlist acceptance rate for the Class of 2028 stands at 23.7%.

Over the past eight admission cycles, UCSD’s waitlist acceptance rate has bounced around quite a bit, showing just how unpredictable the process can be. Let’s take a look at the table to understand the trend better:

Looking at the bigger picture, over the past eight years, UCSD’s waitlist acceptance rate has averaged about 14.6%, with an average of roughly 26,076 waitlisted, 16,595 students opting in, and about 2,873 being admitted each year.

The most extreme case in the recent past was the Class of 2025, where not even a single student was admitted from the 8,835 who opted in, giving us a 0% waitlist acceptance rate. On the other end of the spectrum, the Class of 2024 had the highest acceptance rate at 26.8%, when 5,282 waitlisted students got in.

Going back further, the Class of 2023 was also generous when over 21.6% of waitlisted students got in. But the Class of 2026 saw just 4.7% admitted. These year-to-year changes depend on how many admitted students enroll, which is known as the yield rate. 

In years when fewer students take their offer, UCSD turns more to the waitlist to fill its spots. In years when enrollment is higher, there’s very little room left, and the waitlist barely moves.

So the bottom line is that getting off UC San Diego’s waitlist is an uncertain bet. Some years, thousands are admitted; other years, almost none. Therefore, if you happen to be on the waitlist, it’s nice to be optimistic, but it’s also realistic to have a solid backup plan.

Is It Worth Staying on UC San Diego’s Waitlist?

Being placed on UC San Diego’s (UCSD) waitlist means you’re still in the running, but there is no guarantee that you will be admitted. So, still choosing to stay on the waitlist depends on your personal preference and how ready you are to accept the uncertainties that come along.

Looking at the positive side of things, staying on the UCSD waitlist keeps open the possibility of admission. The reason is that in some years, UCSD has admitted a significant number of students from the waitlist.

For example, for the Class of 2028, about 23.7% of those who accepted their spot on the waitlist were eventually admitted. So, if UCSD is your top choice and you would wholeheartedly attend if admitted, it might be worth taking the chance.

But you must keep in mind that this comes with its own set of pros and cons. First, you will need to commit to and deposit at another school by the May 1 national deadline to secure your place for fall because UCSD waitlist decisions can come as late as July or August. 

Now, this means financially and emotionally managing and staying ready to attend one school while hoping for admission at UCSD later. There is never a guarantee of admission. Waitlist admit rates have varied widely, including years when no waitlisted students were admitted, which, of course, can be distressing.

Ultimately, staying on UCSD’s waitlist is worth it if UCSD is your clear first choice and you can keep up with the wait. But be prepared with a solid backup plan because the waitlist process is highly unpredictable, and admissions offers can come with little notice. 

UCSD Waitlist Acceptance Rate vs Other UC Schools

No matter which UC you’re aiming for, getting off the waitlist is a challenge. The numbers can be a bit surprising, but they give you a clear sense of what you’re up against. Let’s understand this further with the help of the table given below:

Looking at these figures, the average waitlist acceptance rate across these five campuses is 36.4%. But that’s somewhat tricky. The gap between the highest and lowest rates is huge.

On one end of the spectrum, UC Irvine admitted 100% of its waitlisted students (likely due to unique enrollment needs). On the other end, UC Berkeley accepted just 0.3%, which means only 3 out of every 1,000 waitlisted students got in.

Next, for UCSD specifically, 23.7% is well above UCLA’s 13.2% but far below UC Irvine’s 100% and UC Davis’s 44.8%. Statistically speaking, that puts UCSD in the “moderate chance” zone compared to its peers.

If we look at the bigger picture, in an average UC cycle, each campus waitlists thousands of students, and only a fraction of them receive acceptance offers. UCSD’s odds may feel better than some, but they still mean more than 3 out of 4 waitlisted students won’t make it in.

The bottom line is to not assume you’ll be admitted from the waitlist, even with UCSD’s comparatively higher rate. If you’re on the waitlist, strengthen your application updates, keep your grades high, and show genuine interest. At the same time, have a solid backup plan, as waitlist outcomes can be unpredictable.

What to Do If You’re Waitlisted by UCSD

Getting waitlisted at UC San Diego can feel confusing, like you’re stuck between yes and no. To keep it simple, here’s what you should know:

1. Confirm your UCSD waitlist spot.

You must log in to your UC Applicant Portal and actively confirm your place on the waitlist, ensuring all UCSD waitlist requirements are met, as UCSD will not do this automatically. It’s a crucial step.

For first-year applicants, the deadline is generally April 15, 11:59 PM, and if by chance you miss it, you’ll no longer be considered for admission this year.

2. Avoid sending any extra materials.

This is where UCSD differs from many private colleges: they strictly do not accept additional materials from waitlisted students. That means you are not supposed to share letters of continued interest (LOCI), no updated grades, awards, activities, or new recommendation letters. Your application will be reviewed exactly as it was submitted.

3. Keep your grades strong.

Even while you wait, your senior-year grades still matter. If UCSD admits you, they will check your final transcript, and they can take back the offer if your grades fluctuate or drop a lot, you fail a required course, or there’s any issue with academic honesty.

4. Commit to another school by May 1.

Do not rely only on UCSD. You must make sure you submit your statement of intent to register (SIR) to another school by May 1, even if UCSD is your first choice. So, if UCSD gives you a spot later, you can still switch, but then you may lose your deposit at the other school.

5. Stay alert for updates from UCSD.

After May 1, UCSD will review how many admitted students have accepted their offers and determine how far they will go into the waitlist. This process can extend into late July or even early August. If you receive an offer, you may have as little as 72 hours to respond, so be prepared to act quickly.

6. Have a realistic approach. 

Being on the waitlist means you still have a chance, but it’s not guaranteed. It’s important to stay hopeful but also prepare yourself for other outcomes. Keep exploring options, stay positive, and don’t put all your hopes on UCSD alone. It is always a wise decision to make space for a backup plan.

Frequently Asked Questions

1. How many students usually get off UCSD’s waitlist?

That depends on the year. Sometimes UCSD brings in a lot of students who are on the waitlist, like around 4,500 in 2024, and other times, almost no one. In 2021, for example, zero students were admitted from the waitlist. So while there’s definitely a chance, there’s still no guarantee. It totally depends on how many admitted students end up saying yes.

2. When will UCSD release waitlist decisions?

UCSD starts making waitlist decisions after May 1, once they know how many admitted students plan to enroll. Some offers may go out in May or June. But it can take until July or even August as well before the process is completed. So, if you’re admitted, your notice will come through the portal or email, and you will have just a couple of days to respond.

3. Does UCSD rank students on the waitlist?

The answer is no. There is no number next to your name. UCSD (like all UC schools) doesn’t rank the waitlist. If they need to fill certain majors or student profiles, they will go back and review applications based on the enrollment needs of the campus and not who joined the list first or who had the highest GPA.

4. Can I do anything to boost my chances while on the waitlist?

To be honest, you cannot do much. UCSD will not accept letters of continued interest (LOCI), updated grades, awards, or recommendation letters unless you are contacted by them. So, your original application stands as it is. All you have to do is stay strong academically and be patient.

5. What happens if I don’t accept my spot on the waitlist?

If you don’t respond and opt in through your UC application portal by the deadline (which is  April 15), UCSD will not consider you for a spot after that point. So if you’re still interested, don’t miss the deadline to respond.
