When Does Caltech Release Decisions?

Caltech releases decisions at different times depending on the application plan. Restrictive Early Action applicants typically hear back in mid-December, while Regular Decision applicants are notified in mid-March. Waitlist updates extend into the summer months, and transfer decisions are announced in early May.

Here’s a quick overview of when Caltech decisions come out for each application type:

For the Class of 2029, Caltech’s Restrictive Early Action decisions were released on December 12, 2024, while Regular Decision results came out on March 8, 2025. Expect a similar pattern for the Class of 2030, with REA notifications around December 12–14, 2025, and RD decisions in March 2026.

When Do Caltech Early Action Decisions Come Out?

When do Caltech decisions come out for its Restrictive Early Action? Students applying through Caltech’s Restrictive Early Action route get their decisions much earlier than those waiting for Regular Decision, typically around December 15.

Here’s the full REA timeline:

While the Restrictive Early Action application is due November 1, Caltech allows applicants until November 6 to submit required and supplemental materials, with standardized testing to be completed by November 30.

REA decisions typically arrive in mid-December via the applicant portal. Caltech will send an email letting you know the update is available, but you’ll need to log in to view the result.

What is Caltech Early Action?

Restrictive Early Action (REA) is a non-binding early admissions process for students who are confident that Caltech is their first-choice university, excited about the possibility of attending Caltech, and want to learn early if they are admitted to Caltech.

At the same time, students will not be required to accept a Caltech REA offer and may compare financial aid options if they choose to apply to other institutions during the Regular Decision process.

Applications are due November 1, and students will be notified of their admissions decision (admit, defer, or deny) by mid-December. Admitted students will then have until May 1, 202,6, to decide if they will accept Caltech’s offer of admission.

Students who choose to apply REA to Caltech may not apply Early Action or Early Decision to any other institution, with the following exceptions:

• Universities located outside the United States
• Public institutions with a non-binding fall admission policy, such as the University of California system
• Colleges that offer non-binding rolling admissions
• U.S. military academies
• Scholarship or special academic programs at other schools (public or private) that require an early, non-binding application for consideration

If you are deferred admission after applying to REA at Caltech, you may apply to another institution’s Early Decision II program. If you are admitted to that institution’s Early Decision II program, you are required to withdraw your application for admission to Caltech.

Caltech Early Action results

When Caltech decisions come out for REA, there are three possible outcomes:

• Admit. Congratulations—you’re in! You’ll have until May 1 to decide whether to enroll.
• Defer. Your application moves into the Regular Decision pool for further review. Caltech defers only a small number of applicants.
• Deny. Your application is closed for this cycle. Denied students cannot reapply to Caltech in the same year but may apply in the next cycle.

Caltech Early Action acceptance rate

Caltech does not publish a separate acceptance rate for Restrictive Early Action. What the admissions office has shared is that the early admit rate is below 5%, making it nearly as competitive as Regular Decision.

For context, the overall acceptance rate for the Class of 2028 was just 2.3%, one of the lowest in the nation. In other words, applying early doesn’t provide much of a statistical advantage—the applicant pool remains highly competitive across both rounds.

When Do Caltech Regular Decisions Come Out?

For most applicants, Caltech decisions come out in mid-March through the Regular Decision process. Here’s the RD timeline:

The Caltech Regular Decision application process follows a set timeline each year. Applications open on August 1, giving students the opportunity to begin working on their materials early. The Regular Decision application itself is due by January 5, and all required supporting materials—such as recommendation letters and transcripts—must be submitted by January 11.

For those submitting standardized test scores, the last possible testing date is December 31. Admission decisions are released in mid-March, and students who are admitted must confirm their enrollment by the national reply deadline of May 1.

What is Caltech Regular Decision?

Regular Decision is the most common application route at Caltech. It’s non-binding, giving you more time to complete your application and compare offers from multiple schools.

This round is also when Caltech admits the majority of its incoming class. However, because more students apply through RD, the competition is intense and the acceptance rate is significantly lower.

Caltech Regular Decision results

When Caltech decisions come out in mid-March for RD, you can expect these outcomes:

• Admit. You’re offered a spot at Caltech and must reply by May 1.
• Waitlist. You’re placed on hold until after May 1, depending on available spots.
• Deny. Your application is closed for the cycle, but you may reapply in the future.

Caltech Regular Decision acceptance rate

Caltech’s admissions data does not include a separate acceptance rate for Regular Decision. What is clear, however, is that both RD and EA are among the most competitive admissions routes in the country, each with admit rates under 5%. For the Class of 2028, Caltech’s overall acceptance rate was just 2.3%, making it the most selective university in the United States.

Although exact RD numbers aren’t published, applicants should expect the competition to be equally tough in both rounds. Whether you apply in December or March, the odds remain slim—meaning every part of your application needs to be outstanding.

When Do Caltech Waitlist Decisions Come Out?

Caltech follows a fairly consistent pattern for its waitlist process, though exact dates may vary slightly each year. Here’s what the typical timeline looks like when Caltech decisions come out for waitlisted applicants:

After Regular Decision results are released in mid-April, students who are placed on the waitlist receive instructions on how to opt in if they wish to remain under consideration. By late April, students must confirm their spot on the waitlist, as those who do not respond are automatically removed.

On May 1, which is National College Decision Day, Caltech reviews enrollment numbers to determine whether additional offers can be extended. If space becomes available, offers to waitlisted students are typically made between late May and early July, with most waitlist activity concluding by early July.

This timeline highlights the importance of confirming your waitlist spot promptly and staying prepared for quick updates from the admissions office.

Over the past five admissions cycles, Caltech’s waitlist acceptance rate has fluctuated dramatically. Most cycles see little to no movement, but occasional years admit a small group of students.

For instance, in the Class of 2028, 206 students were offered waitlist spots, 171 accepted their place, and 41 were eventually admitted, yielding a waitlist acceptance rate of about 24%. By contrast, in other years, no waitlisted students were admitted at all.

When Do Caltech Transfer Decisions Come Out?

Transfer applicants follow a different admissions cycle. When Caltech decisions come out for transfer applicants, they typically happen in early May, giving students time to finalize enrollment by June.

Here’s the transfer timeline at Caltech:

For students applying to transfer to Caltech, the application deadline is February 1. Any required transfer exams must be submitted by February 15. Admissions decisions for transfer applicants are released in early May, and those who are admitted must confirm their enrollment by the reply deadline of June 1.

Caltech’s transfer admissions are among the most selective in the country. The acceptance rate hovers around 6%, meaning very few applicants earn a spot. For the Class of 2028, just 11 students were admitted out of 178 applicants, and only 10 ultimately enrolled. With such limited availability, transfer admission is considered one of the most competitive pathways into Caltech.

What to Do After Receiving Your Caltech Admissions Decision

When Caltech decisions come out, knowing how to respond is key. Here’s how:

Accepted

Celebrate your achievement! Confirm your spot by May 1 and review your financial aid package carefully. Connect with future classmates and start preparing for the transition.

Beyond logistics, take advantage of admitted student events and virtual meetups hosted by Caltech. These opportunities allow you to learn more about the community, meet professors, and build connections with peers before you even arrive on campus.

Start preparing academically too—look at research opportunities, summer prep courses, or ways to strengthen your foundation in math and science so you feel ready for the rigor ahead.

Deferred

A deferral is not a rejection. Send a letter of continued interest, highlight recent achievements, and maintain strong grades. Stay engaged in activities that show your intellectual curiosity.

Think of this as a second chance. Use the extra time to deepen your academic profile—whether that’s through science fairs, publishing work, or taking advanced coursework. Admissions officers want to see that you’ve maintained momentum. Keep your updates concise and meaningful, focusing on quality over quantity, and avoid overwhelming the admissions office with too many submissions.

Waitlisted

If you want to remain in consideration, confirm your waitlist spot and send meaningful updates. However, secure enrollment at another college by May 1—you may or may not be admitted from the waitlist.

The waitlist can be unpredictable, so it’s best to view it as a “bonus” opportunity rather than a primary plan. While you wait, express your continued interest with a brief update letter and maintain strong academics until the end of the year.

Most importantly, invest emotionally in the college where you deposit—it ensures you’ll be excited about your future regardless of how the waitlist unfolds.

Denied

While disappointing, a denial does not define your future. Take time to regroup and consider reapplying in the next cycle or exploring transfer opportunities later.

Remember that Caltech’s admit rate is under 3%, meaning thousands of highly qualified students receive denials each year. Use this as an opportunity to reflect on your strengths and refine your academic goals.

Many students discover schools that are a better personal or academic fit and go on to excel in ways they hadn’t originally imagined. If Caltech remains your dream, consider applying as a transfer after building a strong record at another top institution.

Frequently Asked Questions

1. Does Caltech offer Early Decision?

No, Caltech does not have an Early Decision plan. Instead, it offers Restrictive Early Action, which is non-binding but limits where else you can apply early. This policy allows students to show a strong interest in Caltech while still comparing offers from other schools later in the process.

2. Can I appeal my Caltech admissions decision?

No. When Caltech decisions come out, they are considered final. Denied students cannot appeal but are welcome to reapply in the next admissions cycle or as transfer applicants. Admissions encourages students to strengthen their academic and extracurricular profiles if they plan to reapply in the future.

3. How does Caltech notify applicants of decisions?

When Caltech decisions come out, all notifications are released through the applicant portal. You’ll receive an email when the update is ready, but you must log in to view the result. This ensures each applicant accesses their official decision directly and securely.

4. Does Caltech require SAT or ACT scores?

Yes. Caltech requires first-year applicants to submit standardized tests, either the SAT or ACT. For Fall 2026 applicants, the ACT Writing and Science subscores are not required.

Caltech also does not consider a composite ACT score; instead, the admissions committee evaluates individual section scores (Math, English, Reading, and optional subscores). Test scores are reviewed as one component in a holistic evaluation process, alongside academics, essays, and recommendations.
