Brown's early decision acceptance rate swings hard from year to year — 13 percent one cycle, nearly 18 the next. Read those swings as Brown changing its appetite and you will misread every one of them.
But before the swings, something more basic: Brown publishes its early numbers twice, and the two versions do not match.
Two ledgers
In December, when decisions go out, Brown issues a press release. In April, it files a Common Data Set — the standardized form colleges complete for guidebooks and researchers. Both are Brown. They disagree.
| Entering class | Announced in December | Filed in the CDS |
|---|---|---|
| Class of 2027 | 879 admitted | 884 |
| Class of 2028 | 898 admitted | 898 |
| Class of 2029 | 906 admitted | 907 |
| Class of 2030 | 890 admitted | not filed yet |
The gaps are small, and that is the point — these are not different stories, they are the same story at two levels of finality. December is a same-day count. April is the audited one, after deferrals, withdrawals and late resolutions settle.
Brown even corrected itself in public: an editor's note appended to its Class of 2029 release revised the early admits from 906 to 907 and the pool from 5,048 to 5,055. Most sites still quote 906. The filing says 907.
Where the two disagree, we use the filing. Where only the press release exists — as with the Class of 2030, whose CDS will not appear until spring 2027 — we say so.
The seats barely move
Now look at the filed column on its own:
896 · 884 · 898 · 907 — four cycles, a band of twenty-three students.
That is effectively a constant. The rate moves because you move. When fewer applicants show up early, the rate climbs; when the pool swells, it compresses. Early applications rose by about 350 into the Class of 2030 cycle, and the rate fell accordingly. (Cornell's early numbers move for the same reason, with the added wrinkle that Cornell stops releasing them at decision time.)
The Class of 2027's frightening 13 percent and the Class of 2029's friendly 17.9 describe nearly identical decisions by Brown and very different decisions by everyone else.
That reframe changes what the number is for. Brown's ED rate is not a forecast of your odds; it is a census of your competition. Around 890 to 910 seats will be offered early next cycle with a confidence you can nearly bank. The only live question is how many people stand in line with you.
Why this page shows you two different rates
Further down, you will see a data block reporting Brown's 2025-2026 filing: 907 admitted of 5,062 early applicants, and a rest-of-pool rate of 4.8 percent.
Brown's December release for the Class of 2030 reported a regular-decision rate of 3.94 percent — 1,674 admitted of 42,531.
Those are different numbers because they are different cycles and different definitions: one is the audited filing for the class that entered in fall 2025, the other is a same-day announcement for the class entering in fall 2026, and "rest of pool" is not identical to "regular decision" once deferrals are counted.
We could have shown you only the one that reads better. Both are on the page instead, each labelled with where it came from. If a site gives you a single tidy figure with no source, it has quietly chosen for you.
The gap that deserves your attention
For the Class of 2030 — press release, no filing yet — Brown admitted 2,564 of 47,937 applicants overall, 5.35 percent. Split by round: 16.5 percent early against 3.94 percent regular, a better than four-to-one gap.
The regular side is the rigid one. Across the cycles where both halves are computable, Brown's regular rate has sat between roughly 3.8 and 4.0 percent while total admits barely budge. If part of your plan involves the regular window quietly widening in a good year, the data has an answer, and it is no.
The standard caution about early-round multipliers applies here as everywhere: the ED pool is not the RD pool applying early. It carries recruited athletes, QuestBridge matches, and applicants confident enough to sign a binding commitment, so the four-to-one gap overstates what early timing alone buys an unhooked applicant. We walked through that composition logic in our cross-school early decision breakdown. Brown adds a wrinkle this year: QuestBridge admits fell to 52 for the Class of 2030 from 90 the year before — the first drop in over a decade, and a reminder that even the hooked lanes are not fixed.
Discounted for composition, the structural point survives. Binding early admits enroll at essentially full yield; those ~900 students claim seats before the regular round opens; everyone else competes for what remains. At Brown the early round is not a bonus lottery ticket — it is where a disproportionate share of the class is settled. The same seat math shows up across the binding schools, including at Rice, where one binding round works and the other doesn't.
Testing is back, and the pool adjusted
The Class of 2030 was the second to apply under Brown's reinstated SAT/ACT requirement after four test-optional years. The early pool's rebound reads as applicants adjusting to the requirement rather than being deterred by it.
Which makes the score check a gating question, not a finishing touch. Brown's admitted SAT band in the federal data runs 1510 to 1580 — among the highest floors anywhere. One caveat on vintage: that federal figure reflects an earlier cycle than the early-round numbers above, so treat it as the shape of the bar rather than this year's exact line.
The quartile logic cuts two ways: a quarter of admits sat below 1510, carried by exceptional files; and above the mid-1500s, additional points stop doing meaningful work. If your score sits under the floor by a distance, the binding commitment is probably mispriced for you. Check where you stand against Brown's admitted range before the strategy conversation, not after.
How to actually use Brown's numbers
Read the rate as crowd size, not policy. The seats are near 900 and stable. This December's rate will be set by how many classmates decide to apply early — which is why chasing last year's percentage is astrology.
Assume the regular corridor holds. Plan your list as if a Brown deferral or a regular application faces something close to 4 percent, because it will.
Let the band gate the decision. Clear it, and the ED conversation is about fit and commitment — Brown's Open Curriculum is a genuinely distinctive reason to bind yourself, and readers know the difference between that and prestige-shopping. Miss it by a distance, and the honest move is pointing your early card somewhere it buys more.

Early decision counts for the Classes of 2027 through 2029 are from Brown's Common Data Set filings, linked in the data block below. Class of 2030 figures are from Brown's December press release; that cycle's CDS is not yet published. Overall acceptance rate and SAT band are institution-reported figures published through the U.S. Department of Education. Results are data-based estimates and do not guarantee admission.
