Amherst's Two Acceptance Rates, Explained

Amherst College's published acceptance rate for the Class of 2029 is 7.72%, drawn from its own Common Data Set: 1,222 admits out of 15,819 first-time, first-year applicants. That's the figure Amherst's own materials round to "8%" and the one that shows up everywhere else. It's also a blend of two very different outcomes. Applicants who applied Early Decision were admitted at 22.25%. Applicants who applied through any other round, including Regular Decision and QuestBridge, were admitted at 6.78%. Both numbers come from the same CDS filing and the same entering class. The ED rate is roughly three and a quarter times the non-ED rate.

The Decomposition

| Round | Applications | Admits | Rate | Cohort | |---|---|---|---|---| | Overall | 15,819 | 1,222 | 7.72% | Fall 2025 entering class, Class of 2029 (CDS Section C1) | | Early Decision | 971 | 216 | 22.25% | Fall 2025 entering class, Class of 2029 (CDS Section C21) | | Non-ED (RD + QuestBridge) | 14,848 | 1,006 | 6.78% | Fall 2025 entering class, derived from C1 minus C21 |

Show the math: 216 of 971 ED applicants were admitted, 216 / 971 = 22.25%. Amherst's CDS reports a Section C1 grand total (15,819 applications, 1,222 admits, all rounds combined) and a Section C21 Early Decision subtotal. Subtracting one from the other isolates everyone admitted outside the binding round: 15,819 minus 971 is 14,848 non-ED applications, and 1,222 minus 216 is 1,006 non-ED admits. 1,006 / 14,848 = 6.78%.

How Much of the Class ED Actually Fills

Amherst's own Class of 2029 profile states that ED students made up 43% of the 485-student enrolled class, roughly 209 students. That figure lines up closely with the 216 ED admits reported in the CDS, which makes sense given that Early Decision is binding and effectively yields close to 100%. Put plainly: at Amherst, nearly half of an entering class of under 500 students is locked in before Regular Decision applicants even find out whether they got in. That's not a marginal effect on the admissions math, it's a defining one.

One year earlier, for the Class of 2028, the same pattern held with different numbers. Amherst's CDS shows 13,743 total applicants and 1,238 admits that cycle, an overall rate of 9.01%. Its ED breakdown was 735 applications and 216 admits, a 29.4% ED rate, with a non-ED rate of 7.86% (1,022 admits out of 13,008 applications). Comparing the two cycles: total applications grew from 13,743 to 15,819, the ED applicant pool grew even faster, from 735 to 971, and the ED admit rate fell from 29.4% to 22.25% as a result. Notably, ED admits stayed exactly flat at 216 both years, which suggests Amherst is targeting a fairly consistent ED class size year over year even as the applicant pool competing for those same 216 spots keeps growing.

Why the Gap Is This Big

Early Decision is a binding agreement. A student admitted ED to Amherst is committing, in writing, to enroll and to withdraw every other application. That commitment removes the largest source of uncertainty in the admissions process: yield, the share of admitted students who actually enroll. A Regular Decision admit is always a projection, because Amherst has no way to know in advance how many RD admits will choose to enroll elsewhere. An ED admit carries none of that uncertainty, which is exactly why ED yield runs close to 100% and RD yield does not.

That certainty lets Amherst extend admission to a much larger share of a comparatively small ED pool. And because roughly 43% of the enrolled class comes from that binding round, the Regular Decision committee is working with far fewer remaining seats relative to a much larger remaining applicant pool. That's a mechanical effect, not a statement about the relative strength of RD applicants: when a small liberal arts college fills close to half its class before Regular Decision applications are even reviewed, the math on what's left over gets tighter by necessity.

The same logic runs in reverse for the non-ED pool. Nearly 15,000 applicants competing for 1,006 spots isn't 15,000 students who are weaker than the 216 ED admits. Many strong applicants apply Regular Decision specifically because they need to compare financial aid packages across schools, something a binding ED commitment doesn't allow. The non-ED pool includes students who could have been competitive ED admits elsewhere but deliberately kept their options open. A lower non-ED rate largely reflects a much larger applicant pool competing for the seats left over after ED has already claimed a defining share of the class, not a judgment on non-ED applicant quality.

What This Means for Your Application

If Amherst is genuinely your first choice and your family's finances work without needing to compare aid offers across multiple schools, this gap represents a real structural advantage. A pool admitted at more than three times the non-ED rate, filling nearly half the entering class, is a meaningful difference in your odds. But that advantage only makes sense if you can commit to the binding terms. ED means withdrawing every other application and enrolling at Amherst if admitted, regardless of what other offers or financial aid packages show up later.

It's worth being direct about what the gap doesn't tell you, too. The ED applicant pool at Amherst is not a random cross-section of the same students who apply Regular Decision. Recruited athletes, legacy applicants, and students who have already decided with certainty that Amherst is their top choice are all disproportionately represented in that pool. That means the 22.25% versus 6.78% gap overstates what applying ED would do for an identical applicant with an identical file. Some of the advantage is the binding commitment itself; some of it is who tends to self-select into ED in the first place. Don't read this gap as a promise that switching rounds alone would triple your odds.

For a broader look at how this same ED-versus-everyone-else split shows up at other selective colleges, our real acceptance rates series breaks it down school by school. And if you're still working out where Amherst fits against the rest of your list, our college list builder can help you compare its ED math against your other target schools before you commit to a round.

Deciding whether to apply ED to a school that fills 43% of its class through a binding round before RD decisions are even released is a real strategic question, not a formality. A free strategy call can help you think through Amherst's numbers against the rest of your list.

The Waitlist Numbers

Amherst's Class of 2029 CDS shows meaningful waitlist activity. The college offered a waitlist spot to 1,294 qualified applicants, and 740 accepted a place on the list. Of those, 44 were eventually admitted, an admit rate of roughly 5.9% among students who accepted a spot on the waitlist. That's a real path in, though a narrow one relative to either admissions round above. If Amherst places you on the waitlist, treat it as worth staying engaged with, not a guaranteed backup plan. Our application deadline tracker can help you track waitlist response windows alongside deadlines from other schools while you wait.
