Hamilton's ED Rate Is 2.4x the Non-ED Rate

Hamilton College's published acceptance rate for the Class of 2029 (Fall 2025 entering class) is 13.6%, straight from Hamilton's own Common Data Set: 1,210 admits out of 8,904 applicants. That figure is accurate, and it also blends two very different outcomes into one number. Applicants who committed through Early Decision were admitted at 28.1%. Applicants who came in through every other channel were admitted at 11.5%. More than double the odds, from the same filing, for the same entering class.

The Decomposition

Show the math: Hamilton's Common Data Set 2025-26 reports 1,210 total admits from 8,904 total applicants for the Class of 2029 (Section C1), and separately 315 admits from 1,120 Early Decision applications (Section C21). Subtracting the ED figures from the overall totals isolates everyone outside the binding round: 8,904 minus 1,120 is 7,784 applications, and 1,210 minus 315 is 895 admits. 895 divided by 7,784 is 11.5%. Hamilton's CDS reports only one binding Early Decision plan and answers "No" to offering a separate Early Action option, so this non-ED figure functions as Hamilton's full Regular Decision rate, with no early-action pool blended into either side.

A Pattern Across Two Cycles

One year earlier, for the Class of 2028 (Fall 2024 entering class), Hamilton's Common Data Set shows 8,531 total applicants and 1,162 admits, an overall rate of 13.62%, essentially flat against the Fall 2025 figure. Of those, 839 applied Early Decision and 247 were admitted, an ED rate of 29.44%. The derived non-ED rate for that cohort was (1,162 minus 247) divided by (8,531 minus 839), or 915 divided by 7,692, which comes to 11.90%.

Across both years the pattern holds steady. The ED rate ran about 28-29%, and the non-ED rate ran about 11.5-11.9%, keeping the gap at roughly 2.4-2.5x in both cohorts. What did change is the size of the ED pool itself, growing from 839 applications to 1,120 while ED admits rose from 247 to 315. The blended headline rate stays close to the RD rate rather than splitting the difference between the two rounds, because Regular Decision applicants vastly outnumber ED applicants: 7,784 of 8,904 total applicants in the most recent cycle, or roughly 87% of the pool.

Why the Gap Is This Big

Early Decision at Hamilton is binding. A student admitted ED has agreed in advance to enroll and to withdraw applications everywhere else. That commitment removes yield uncertainty, the central variable every admissions office manages when shaping an incoming class. A Regular Decision admit's enrollment is still a probability, since RD admits are typically weighing offers from multiple schools before deciding. That uncertainty pushes RD admission rates down, because a college has to admit conservatively enough to hit its target class size even accounting for RD admits who enroll elsewhere. This is a general mechanic of binding admission plans, not a claim that ED applicants to Hamilton are inherently stronger than RD applicants.

The RD pool is also a different population from the ED pool almost by definition. Committing ED means naming Hamilton a first choice before seeing a financial aid offer. Students who need to compare aid packages, who are waiting on a fall semester's grades to strengthen their file, or who haven't settled on Hamilton as a clear first choice tend to apply Regular Decision instead. An 11.5% non-ED rate reflects a much larger, later-stage pool competing for whatever seats the ED round hasn't already filled. It says nothing about how strong that pool is relative to the ED applicants, only that it's larger and facing fewer remaining spots.

What This Means for Your Application

The 28.1% ED figure isn't a rate you can borrow for an identical Regular Decision application. The ED and RD pools are different populations, so the roughly 2.4x gap between them overstates what switching rounds alone would do for one specific applicant with one specific file. It reflects the odds each pool actually faced, not the odds available to a single student choosing between rounds.

ED is also a binding financial commitment. Agreeing to Hamilton's Early Decision plan means committing to enroll before you've seen its financial aid offer and before you have any ability to compare that offer against another school's package. Once a signed ED acceptance is in, there's no leverage left to negotiate or shop the offer, so any aid comparison needs to happen before you apply ED, not after.

Hamilton is an open-curriculum liberal arts college with a single undergraduate college and no separate schools or divisions admitting applicants independently; its own Common Data Set states admissions factors don't vary by intended academic program. There's no per-major breakdown to weigh here. The 28.1% and 11.5% figures already describe Hamilton's entire applicant pool. Our college list builder can help you see how Hamilton compares against the rest of your list, and our application deadline tracker can help you keep its ED and Regular Decision dates straight.

Because Hamilton has no Early Action option, the choice for most applicants is binary in a way it isn't at schools with a non-binding early round. There's no middle path that lets you apply early to Hamilton without a binding commitment. That makes the financial-aid timing question especially important: if your family needs to see multiple aid offers side by side before committing, Regular Decision is the only path that preserves that comparison at Hamilton specifically, since there's no non-binding early option to split the difference.

If Hamilton is a genuine first choice and financing isn't the deciding factor, the ED numbers reflect a real structural advantage. Talk to a Dewey Smart advisor if you're still weighing whether that commitment fits your family's situation.

The Waitlist

Hamilton's Fall 2025 Common Data Set reports 2,032 qualified applicants were offered a spot on the waitlist. Of those, 1,226 accepted the spot, and 49 were ultimately admitted off the waitlist, a conversion rate of about 4.0% among students who accepted. The waitlist is unranked, per the filing.

That 2,032-student waitlist pool is more than 20% the size of Hamilton's entire regular applicant pool, a reminder that being waitlisted at a selective liberal arts college is common rather than unusual. Most students who accept a waitlist spot won't ultimately be admitted from it, and Hamilton's own data doesn't rank the list, so there's no way to know where a given file sits within it.
