College Acceptance Rates by Major 2026: Why Your Intended Major Changes Your Odds by 2-5x
By Rona Aydin
Does Your Intended Major Actually Affect Your Acceptance Rate?
At many top universities, dramatically yes. According to data from multiple Common Data Sets, the gap between the most and least competitive majors at the same school can be 5x or more. This is one of the most consequential and least understood dynamics in college admissions. The overall acceptance rate a university publishes is an average that collapses wildly different competitions into a single misleading number. A student applying to CMU’s School of Computer Science (<5%) faces a fundamentally different statistical reality than one applying to Dietrich College (~24%) at the same university.
Which Schools Admit by Major and Which Don’t?
This is the first strategic question to answer. According to admissions policies published by each institution, the landscape splits into two categories:
| Admit by Major (rate varies) | Do NOT Admit by Major (rate same) |
|---|---|
| CMU (direct admit to college) | MIT (declare sophomore year) |
| Cornell (by college within university) | Stanford (declare anytime) |
| UCLA (by school within UCLA) | Harvard (concentrate sophomore year) |
| UC Berkeley (EECS vs L&S) | Princeton (declare end of soph year) |
| Georgia Tech (major considered) | Yale (declare sophomore year) |
| UIUC (direct admit to major) | Caltech (all STEM, declare later) |

The strategic implication is enormous. At admit-by-major schools, listing Computer Science puts you in the most competitive pool. At MIT or Stanford, listing CS has no direct effect on your acceptance rate because those schools evaluate you holistically and let you choose your major later.
What Are the Acceptance Rates by Major at Top Schools?
| School | Most Competitive Major/School | Rate | Least Competitive | Rate | Gap |
|---|---|---|---|---|---|
| CMU | SCS (Computer Science) | <5% | Dietrich (Humanities) | ~24% | ~5x |
| UCLA | Nursing | ~1% | Music | ~19% | ~19x |
| Cornell | Engineering | ~5% | Arts & Sciences | ~9% | ~2x |
| UC Berkeley | EECS | <5% | L&S (undeclared) | ~15% | ~3x |
| UIUC | Computer Science | ~6% | University overall | ~45% | ~7.5x |
| Georgia Tech | CS (OOS) | <9% | In-state overall | 28% | ~3x |

Should You List a Less Popular Major to Improve Your Odds?
This is one of the most frequently asked strategic questions in admissions, and the answer is nuanced. According to former admissions officers, listing an intended major that does not match your transcript, extracurriculars, and essays is easily detected and counterproductive. If you have taken no humanities courses beyond requirements and your extracurriculars are all STEM, listing English Literature to avoid the CS pool will not fool anyone. However, if you genuinely have cross-disciplinary interests, listing an adjacent major (data science instead of CS, applied math instead of engineering, economics instead of business) at an admit-by-major school can place you in a less saturated pool while remaining authentic. The key test: can your application genuinely support the major you list? If not, do not try it. For essay strategy, see our Common App essay guide.
Which Majors Are Most Competitive Across All Schools?
According to data from the National Association for College Admission Counseling and institutional reports, the most competitive intended majors in 2026 are: Computer Science (most competitive at every school that admits by major), Engineering (especially Biomedical, ECE, and Mechanical), Business/Finance (especially at Wharton, Stern, Tepper), and Nursing (extremely competitive at UCLA, UPenn, and BC). The least competitive pools tend to be humanities, social sciences, and arts at STEM-heavy schools.

How Does Gender Affect Acceptance Rates by Major?
According to College Transitions, CMU’s acceptance rate for women (15%) was significantly higher than for men (9.7%) for the Class of 2028. This is driven by gender imbalance in STEM applicant pools: programs like CS and Engineering receive far more male applicants, while female applicants face less statistical competition. This does not mean standards are lower for women. It means the applicant pool composition creates different odds. Female students applying to STEM-heavy schools often face meaningfully better statistical odds than male students applying to the same programs.
How Should You Use This Data When Building Your College List?
Three rules. First, at admit-by-major schools, treat the major-specific rate as your real acceptance rate, not the overall rate. CMU’s overall 11% is irrelevant if you are applying to SCS (<5%). Second, build your list with a mix of admit-by-major and non-admit-by-major schools to diversify your risk. If you are a CS applicant, include MIT and Stanford (no major penalty) alongside CMU and Berkeley (major-specific competition). Third, if you have genuine cross-disciplinary interests, consider listing an adjacent major at admit-by-major schools where it is authentic. For building a balanced list, see our summer programs guide and ED vs RD guide.
Final Thoughts: Your Major Is Part of Your Admissions Strategy
Your intended major is not just an academic preference. At admit-by-major schools, it is a strategic decision that affects your odds by 2-5x. Understanding which schools admit by major, what the major-specific rates are, and how to position yourself authentically within the system is essential. At Oriel Admissions, our team of former admissions officers from Harvard, Princeton, and Columbia helps students navigate these strategic decisions.

At admit-by-major schools (CMU, Cornell, UCLA, Berkeley, Georgia Tech, UIUC), dramatically yes. At CMU, SCS (<5%) vs Dietrich (24%) is a 5x difference. At MIT, Stanford, Harvard, and Princeton, your listed major has no direct effect on acceptance rate because those schools do not admit by major.
Only if your application genuinely supports it. Admissions officers detect misalignment between listed major, coursework, and extracurriculars. If you have authentic cross-disciplinary interests, listing an adjacent major (data science vs CS, economics vs business) can place you in a less competitive pool while remaining credible.
For CS specifically, yes. According to institutional data, UIUC’s CS acceptance rate (~6%) is comparable to Cornell’s overall rate (6.9%). The university’s overall rate (~45%) is dramatically higher, but CS applicants face a completely different competition.
Not directly. MIT and Stanford do not admit by major. You can list CS as your interest without facing a CS-specific acceptance rate. However, the overall applicant pool at both schools is heavily STEM-oriented, so the competition is intense regardless of listed major.
Computer Science is the most competitive intended major at every admit-by-major school in the country. Engineering (especially Biomedical and ECE) is second. Business/Finance is third. Nursing is extremely competitive at schools that offer it (UCLA 1%, UPenn, BC).
Statistically, yes. At CMU, the acceptance rate for women (15%) was significantly higher than for men (9.7%) for the Class of 2028. This reflects gender imbalance in applicant pools, not lower standards. Female CS and engineering applicants face less statistical competition than male applicants.
It depends on the school. At CMU, internal transfer into SCS is very competitive. At Berkeley, switching from L&S to EECS is nearly impossible. At Cornell, switching between colleges requires a competitive internal process. Research each school’s policy before applying.
Mix admit-by-major and non-admit-by-major schools. If you are a CS applicant, include MIT and Stanford (no major penalty) alongside CMU and Berkeley (major-specific competition). Treat major-specific rates as your real acceptance rate at admit-by-major schools, not the overall rate.
