Every September, some version of this question shows up in a counselor's office: I have one Early Decision application, and my dream school is a reach. Should I spend it there?
The honest answer depends on a number most people never look up, and it isn't the ED acceptance rate.
What the ED rate describes
Start with the figure everyone quotes. Dartmouth's own Common Data Set for 2025–26 reports 3,552 Early Decision applications and 768 admits. That is 21.6% of the early pool. Everyone who applied in the other rounds faced 3.8%. Northeastern's 2024–25 filing shows something even more lopsided: 43.0% of early applicants admitted, against 3.8% for everyone else.
Those gaps are real, and they are published by the schools themselves. But read what the number is: a rate for a round, calculated over whoever applied in it. Early pools are not random slices of the applicant population. They hold recruited athletes, students whose families have long ties to the school, and — this is the part that matters here — a disproportionate share of applicants who already sit comfortably inside the school's admitted range.
So the 21.6% was earned by a pool that mostly looked like Dartmouth's admitted class before it applied. A file that does not look like that class is not the file the rate describes.
The number that decides it
The second figure is the admitted SAT range, and specifically its bottom edge. Dartmouth's latest reported middle 50% runs 1500 to 1570 (College Scorecard). Tufts reports 1470 to 1560. Northeastern, 1440 to 1540. Emory, 1470 to 1550.
The 25th percentile is a line. Above it, the school's own data says that students with your score are admitted in numbers. Below it, three quarters of the admitted class scored higher than you did, and the ED round does not change that fact. A binding application signals commitment. It does not add points.
This is what "reach" should actually mean. A school is a reach not because its overall acceptance rate is low, but because your file sits below the range the school reports admitting. Those are different things. Dartmouth is a reach for nearly everyone at 6.0% overall — but for a student at 1540, it is a reach where the ED round has real leverage: more than a fivefold difference between the early rate and the rate for everyone else, applied to a file that is inside the band. That is the best case for spending the application on a low-acceptance school.
For a student at 1450, the same school is a different proposition. The early round's advantage was built by files that don't resemble this one. The 21.6% is not on offer.
The trade you are actually making
Here is where the reach-versus-match framing goes wrong. The question is not whether ED "helps" at the reach. It is what you give up by spending the application there.
Take that same 1450 student. At Dartmouth, below the band, the early application buys commitment with little evidence of return. At Northeastern, the same score sits inside the reported range, and the school's own filing shows the early round admitting at eleven times the rate of the other rounds. At Emory — 22.2% early against 8.6% for everyone else, range 1470 to 1550 — the score is just under the line, close enough that a fall retake could change the answer.
Three schools, one score, three completely different uses of the same binding application. The reach-or-match label hides that. The band and the round-level figures reveal it.
Two honest caveats
First, in-band is not a guarantee, and it isn't a probability either. Even inside the range, an ED rate is a fact about the round, not about you. Nothing in a filing lets anyone convert 21.6% into your personal chance, and anyone who does is inventing the number.
Second, the early advantage is uneven and occasionally absent. Case Western's 2025–26 filing shows ED admitted 25.0% while everyone else got 35.6% — the early round was the harder one. Before you assume the round helps at your school, check that it actually did.
What to do this month
Pull your ED candidate's two numbers: the early rate against the rate for everyone else, and the admitted range. Both come from the school's own filings. If you are inside the band and the gap is large, that is the case for a reach. If you are below the band, look at the school one tier down where you are inside it. The application is worth more there, and the school you were going to spend it on will still take a Regular Decision file in January.
Where the numbers come from
Early Decision counts are from each school's Common Data Set, section C21, in the cycle named above; the rate for everyone else is derived from the same document's first-year totals. SAT ranges are the most recent reported middle 50% in the federal College Scorecard. All are public filings, not estimates.
PrepToDone reads those filings back against a real list. Put in the schools you're actually deciding between and your score, and see what each one published about its early round — free, without an account. Naming the one to spend the application on, and why, is the paid part: $49, one time. Start with your list.
