Carnegie Mellon Acceptance Rate: Class of 2029 Data, Early Decision, and What It Means by College

What Is the Carnegie Mellon Acceptance Rate?

The Carnegie Mellon acceptance rate for the Class of 2029, the students who entered in fall 2025, was 11.1%. CMU received 34,867 first-year applications, admitted 3,859, and enrolled 1,804, according to the university’s Common Data Set for 2025-2026. Applications rose by 926 from the prior cycle while admits fell by 100, which pushed the rate down from 11.7% and made this the most selective class in CMU’s history. The yield, meaning the share of admitted students who chose to enroll, came in at 46.7%, up from 45.7%, a sign that CMU is converting a larger share of its offers and therefore needs fewer of them.

Class of 2030 figures, for students entering in fall 2026, will appear in the 2026-2027 Common Data Set, which CMU typically publishes in the spring after the class enrolls. Until then, the 11.1% figure is the current official number, and families applying this cycle should plan around a rate in the low 11% range or slightly below rather than hoping for a rebound.

Why Does the CMU Acceptance Rate Vary So Much by College?

Carnegie Mellon does not admit students to the university and then let them choose a major. It admits them to one of seven undergraduate colleges, each of which reads its own applicant pool against its own seat count, and the university-wide 11.1% is simply the weighted average of seven very different competitions. The School of Computer Science sits at one extreme. CMU no longer publishes per-college admission figures, but the School of Computer Science itself has stated that it turns away almost 95% of the students who apply to its undergraduate program, and that statement dates from a year when the university-wide rate was roughly double what it is now. Dietrich College of Humanities and Social Sciences and the College of Fine Arts sit at the other end, with rates that families should expect to run well above the university average.

Selectivity figures are Oriel Admissions estimates. CMU stopped publishing admission counts by college, so the estimates draw on the university-wide Common Data Set trend, the School of Computer Science’s own published statement, and historical CMU admission profiles; treat them as directional. Testing policies are taken from CMU’s current standardized testing page.

The practical consequence is that a family should never evaluate a CMU application against the 11.1% figure. A student applying to Dietrich with strong writing is facing odds closer to those at a top 30 university; a student applying to the School of Computer Science is facing odds tighter than most Ivy League colleges. CMU asks applicants to rank their college choices, and the choice of first college is the single most consequential strategic decision in the application. Our guide to getting into Carnegie Mellon walks through how to choose it.

What Is the CMU Early Decision Acceptance Rate?

The CMU Early Decision acceptance rate for the Class of 2029 was 20.6%: 553 admitted from 2,680 Early Decision applicants, per the 2025-2026 Common Data Set. That is nearly twice the overall rate, and the 553 Early Decision admits account for roughly 31% of the 1,804 students who enrolled. The prior year’s filing reported 4,423 Early Decision applications and 612 admits, a 13.8% rate, so the Early Decision pool shrank sharply while the Early Decision admit rate rose. Whatever the cause of the smaller pool, the arithmetic for this cycle is clear: a binding application to CMU carried a meaningfully better admit rate than a Regular Decision application.

Two cautions apply. First, Early Decision applicants are a self selected group with stronger average profiles, so part of the gap reflects who applies rather than a bonus for applying early. Second, the Early Decision advantage is concentrated where seats are scarce: in the School of Computer Science, where the overall rate is already in the low single digits, a binding commitment signals certainty to a college that turns away almost everyone, and that signal is worth more there than in Dietrich. CMU runs a single Early Decision round with a November 2 deadline and December 15 notification for the 2026-2027 cycle, and Early Decision is not available for the School of Drama, the School of Music, or the BXA Design programs. Regular Decision closes January 4, with Drama and Music applications due December 1. For the broader decision, see our Early Decision versus Regular Decision analysis.

What GPA and Test Scores Do You Need for CMU?

Enrolled members of the Class of 2029 posted an average high school GPA of 3.89, with 99.7% of students reporting a GPA. The middle 50% SAT composite was 1500 to 1560, with a median of 1540; the Evidence Based Reading and Writing middle 50% was 730 to 770 and the Math middle 50% was 770 to 800, which means a quarter of enrolled students had a perfect Math score. The ACT middle 50% was 34 to 36 with a median of 35. About 65.5% of enrolled students submitted an SAT score and 18.1% submitted an ACT score. These are enrolled student figures; admitted student figures run slightly higher because the strongest admits often choose other schools.

CMU’s testing policy now differs by college, and getting it wrong can void an application. The School of Computer Science requires an SAT or ACT score. The College of Engineering, Dietrich College, the Information Systems program, the Mellon College of Science, and the Tepper School of Business are test flexible, which CMU defines as requiring a test score to complete the application while letting the student choose among the SAT, ACT, IB, AP, Cambridge A Level, or French Baccalaureate results. Only the College of Fine Arts is test optional, and it requires a portfolio or audition instead. CMU superscores the SAT but not the ACT. In practice, for every college outside Fine Arts a strong applicant should plan to submit an SAT or ACT at or above the median, and a School of Computer Science applicant should treat an 800 Math as the expectation rather than the ceiling. Our guide to whether test optional is really optional covers the general logic.

How Does CMU Compare to MIT, Stanford, and the Ivy League?

By the headline number, CMU’s 11.1% looks more accessible than MIT, Stanford, or any Ivy League college, all of which admit in the single digits. The comparison is misleading for the programs most families are actually comparing. A student weighing computer science at CMU against computer science at MIT or Stanford is comparing three programs that each admit a low single digit share of applicants, and the CMU School of Computer Science is, by its own account, the hardest of CMU’s colleges to enter. Where CMU is meaningfully more accessible than its peers is outside computing: Dietrich, the Mellon College of Science, and Information Systems offer a path to a top research university at rates well above what Harvard, Yale, or Princeton offer for any major. Our MIT acceptance rate analysis and top 25 admissions statistics give the peer numbers.

One structural difference matters for list building. MIT and Stanford admit to the university, and a student admitted for one interest can change direction freely. CMU admits to a college, and internal transfer into the School of Computer Science is limited and competitive. A student who is admitted to Dietrich or the College of Engineering hoping to move into computer science later should treat that path as unlikely and should compare the colleges they were actually admitted to, not the university’s reputation as a whole.

What Are Your Chances on the CMU Waitlist?

Slim. For the Class of 2029, CMU offered a waitlist place to 7,117 applicants, 4,937 accepted the place, and 36 were eventually admitted, a 0.7% rate for students who stayed on the list. The year before, CMU offered 16,484 waitlist places, 10,062 students accepted, and 32 were admitted, or 0.3%. The list roughly halved in size while admits from it stayed in the thirties, which is consistent with the higher yield: a university converting more of its offers has less need to go back to the list. Because CMU manages enrollment by college, the handful of waitlist admits typically go to colleges that came in under their target, and a student waitlisted by the School of Computer Science should assume that number is close to zero in any given year.

A waitlisted student who wants to stay in contention should accept the place immediately, send one concise letter of continued interest that adds new information and states plainly that CMU is the first choice, and then commit to another school by May 1. Our guide to writing a letter of continued interest covers the format.

What Does the Carnegie Mellon Acceptance Rate Mean for Your Strategy?

Three conclusions follow from the data. First, choose the college honestly. The most common and most costly mistake at CMU is a student with a strong but not extraordinary computing profile listing the School of Computer Science first, being denied there, and never being read seriously by a college where the same profile would have been competitive. Students who want computing and can accept a different door should look hard at the College of Engineering’s Electrical and Computer Engineering program (see our guide to CMU engineering admissions), Information Systems, or the Statistics and Data Science programs in Dietrich, each of which admits at several times the School of Computer Science rate and each of which leads into CMU’s computing ecosystem.

Second, use Early Decision where it counts. A 20.6% Early Decision rate against 11.1% overall is a real difference, and it is largest for students whose profile is already within range for their chosen college. A student who needs senior fall grades or a retake to reach the median should not spend the binding card early; a student who is already there should.

Third, build the file around the college, not the university. CMU’s supplemental essays ask directly why the student wants a particular college and how they have already pursued that interest, and the readers are faculty adjacent staff in that college. A School of Computer Science application without evidence of mathematics beyond the standard curriculum, or a Tepper application without a quantitative record, reads as a mismatch regardless of the GPA. Our Carnegie Mellon supplemental essay guide covers the prompts, and our best colleges for engineering ranking places the College of Engineering among its peers.
