What separated Carnegie Mellon accepted vs. rejected applicants this cycle? A perfect GPA and a record of academic work beyond school, like selective summer programs and science fair results. Carnegie Mellon University admits about 11.7% of applicants by its official rate, and in our sample admits were nearly twice as likely to have a 4.0. But the number that stands out most at CMU is how many applicants ended up waiting.
We compared 97 Carnegie Mellon applicants from self-reported 2026 r/collegeresults posts: 32 admitted, 29 rejected and 36 waitlisted. This is part of a larger comparison of accepted vs. rejected applicants at top colleges.
People who post results skew strong, so 33% of this sample got in, about three times CMU's real rate. Compare the two groups with each other, not with your own odds. With 32 admits, a gap of a few people can be noise.
Carnegie Mellon admitted student GPA and SAT
| Admitted | Rejected or waitlisted | |
|---|---|---|
| Median unweighted GPA | 4.0 (25 stated) | 3.96 (47 stated) |
| Median weighted GPA | 4.58 (23 stated) | 4.59 (36 stated) |
| Median SAT (scores sent) | 1565 (22 people) | 1545 (50 people) |
| Median ACT (scores sent) | 35 (14 people) | 35 (20 people) |
| Median AP/IB courses | 12 | 12 |
| National-level award | 69% | 78% |
16 of the 25 admits who stated a GPA had a 4.0 (64%), versus 16 of 47 among everyone else (34%). That's an even wider gap than at Stanford. Admits also had a 20-point edge on the SAT (1565 versus 1545), and 96 of the 97 sent scores. Course load was identical, and national-level awards were actually less common among admits. We look at how much GPA mattered across all top schools in does a 4.0 GPA matter at top colleges.
Which activities Carnegie Mellon admits listed more often
- A selective summer program: 47% of admits versus 25% of everyone else, the biggest activity gap at CMU.
- A service or leadership award: 38% versus 18%.
- A science fair award: 25% versus 6%.
- A research publication or paper award: 16% versus 5%.
- Founding an organization: 47% versus 35%.
- Research: 56% versus 46%.
And some showed up more often among applicants who weren't admitted:
- A school award: 16% of admits versus 35%.
- A religious or cultural group: 13% versus 26%.
- Business or entrepreneurship: 16% versus 28%.
- Debate, speech or Model UN: 6% versus 17%.
Admits more often showed academic work that someone outside their school had judged: a competitive summer program, a science fair result, a published paper. Awards from their own school, which many strong students earn, were more common among non-admits. That doesn't mean they hurt. They just didn't set anyone apart.
Computer science and engineering applicants made up most of both groups (23 of 32 admits and 44 of 65 non-admits). Their admit rate in this sample was about the same as everyone else's: 23 of 67, versus 9 of 30. CMU admits students into specific colleges within the university, and its School of Computer Science is far harder to get into than the school-wide rate suggests, so your intended program matters more than this sample can show.
Early Decision and the waitlist
CMU offers binding Early Decision I and Early Decision II. Only 5 applicants in this sample named ED I, too few to compare. If CMU becomes your first choice after December results, ED II is another option; check our list of ED2 deadlines by school and CMU's own site for the date.
The waitlist is the main story at CMU. 36 of the 97 applicants (37%) ended on the waitlist. That's the highest share of any school in our data with at least 30 decisions, ahead of Vanderbilt, Cornell and NYU. Almost no waitlisted applicants were admitted later. If you're waitlisted at CMU, you're in a big group, and you should commit to another school by May 1 while you wait. We cover how to handle a waitlist spot in college waitlist strategy.
What Carnegie Mellon applicants can take from this
- A 4.0 mattered a lot. Admits were nearly twice as likely to have one.
- Show academic work judged outside your school. Selective summer programs, science fair awards and research publications stood out.
- Your intended program matters. CMU admits by college, and computer science is much harder to get into than the overall rate.
- Be ready for the waitlist. More than a third of this sample landed there, and very few got in from it.
