What is Early Decision? How ED works, plus 2026-27 deadlines

Brown delivered 890 acceptance letters, or 16.4%, to Early Decision applicants last December. Each of those students committed in November to enroll if admitted. That’s how Early Decision (ED) works: you increase your chance of acceptance in exchange for committing to a school.

For the Class of 2031, the Early Decision deadline is looming: November 1, 2026, for most schools.

Here’s what you need to know before applying ED.

• Is there one college you’d pick over every other school on your list?
• Can you afford to look at only one aid package?
• Are your grades strong enough through junior year?

If you answered yes four times, Early Decision should be part of your plan. If not, read the cons section below.

What is Early Decision?

Early decision is a binding college application. You apply to your first-choice school early, usually by November 1, and hear back in mid-December. If admitted, you withdraw every other application.

Colleges reward ED with a higher acceptance rate because a binding admit is a guaranteed enrollee.

How Early Decision works, from your signature to December 

ED applicants submit an Early Decision Agreement along with the application. Duke lists it on its 2026-2027 checklist right next to the transcript and counselor recommendation. On the Common App, you sign it, a parent signs it, and your counselor delivers the final sign-off.

You only get one ED school per round, so choose wisely. You can usually apply Early Action to other schools at the same time, as long as they’re non-restrictive. For instance, Notre Dame’s restrictive early action bars applicants from applying ED elsewhere.

Schools also commonly ask ED applicants for a CSS Profile and FAFSA by the deadline. That’s what determines your aid offer in December.

The aid offer is your only real exit after signing an agreement. Emory describes ED I applicants as committing to enroll if they receive adequate financial aid — so you do have somewhat of an out.

December brings one of three answers

• Admitted: you withdraw every other application. The Common App publishes instructions telling ED admits to contact each of their other colleges directly to withdraw.
• Deferred: your file rolls into the regular decision for a second read. Don’t count on this process to deliver a positive result. Williams College deferred 157 of its 1,023 applicants last December, and its Dean said only a small number of those students got in regular decision.
• Denied: you’re done at that school for the year. Time to move on to Plan B.

Early Decision II

ED II offers the same generous admissions odds with a January deadline. For 2026–2027, University of Chicago, Johns Hopkins, Vanderbilt, Rice, Washington University, Emory, Boston College, and Tufts will all have an ED II round.

ED II is an underrated tool in your arsenal. A December deferral from your dream school is the moment to submit to your second choice.

Early Decision acceptance rates for the Class of 2030

We only included schools that released both an ED applicant count and an acceptance rate for the Class of 2030, the cycle that just wrapped up in 2026. Estimates from college consulting sites didn’t make the cut.

Comparing regular decision to early decision makes the latter look like a no-brainer. Brown admitted 3.9% from its regular pool, Duke 3.7%, while Vanderbilt hit a record low at 2.8%.

The gap flatters ED, though. Early pools are stacked with hooked applicants. Duke’s 13.8% ED rate includes legacies and recruited athletes, so unhooked applicants should be wary of those odds.

The pros of Early Decision

Better admission odds. The table above makes the case. A binding decision tells a college you’ll show up. And schools like a yield rate they can control.

Less competition. Duke received 55,776 regular decision applicants for the Class of 2030, about 9x its ED pool. Your file gets read from a smaller pile.

The loudest signal of demonstrated interest. Applying early, especially under a binding commitment, shows colleges you’re serious about attending. No campus tour or thank-you email touches this for demonstrated interest.

You get your spring back. Johns Hopkins lets applicants know they were accepted ED in early December. Admitted students get four months of senior year without a single portal refresh.

The cons of Early Decision

You can’t shop aid offers. An ED admit arrives with one aid package and nothing to compare it to. If merit money matters to your family, read up on how to compare financial aid packages before you sign anything binding.

Your senior year barely counts. ED captures what you did through junior year. Some schools leave a door slightly ajar: some accept first-quarter grades and a trailing SAT score. But if you need a strong senior fall to make your case, waiting for Regular Decision might be the right call.

A December decision leaves you with less runway. With ED decisions arriving in mid-December, students who wait for December results might spend winter break in a panic.

The commitment outlasts your feelings. Seventeen-year-olds change their minds all the time. A crush formed on a sunny October afternoon during a campus visit is a thin basis for signing a binding agreement.

Early Decision deadlines: ED I and ED II 2026-2027

Dates below come from each school’s official admissions page.

Not on the list: Harvard, Yale, Princeton, Stanford, MIT, Caltech, Notre Dame, and Georgetown don’t offer ED. Instead, they use restrictive or single-choice early action.

Two plan changes worth knowing this year. WashU added an early action option for fall 2027 applicants, listed alongside its two ED rounds. The University of Florida also added early decision for the 2026-27 cycle.

Your Early Decision playbook

Early fall: run your first-choice school’s net price calculator with a parent in the room. If the number makes anyone think twice, ED probably isn’t your plan.

By October 25: finalize the ED application. Start two regular decision essays the same weekend, while you still care.

November 1 or 2: submit, then confirm the agreement, transcript, and counselor materials show as received in the portal. 

November: finish your regular decision applications. All of them. Writing them in November will feel pointless right up until December 15.

Mid-December: open the portal. If it’s a deferral or a denial, your ED II school is waiting, and its deadline is in early January.

Skip ED entirely if you can’t name a first choice by Halloween. A forced favorite is worse than no favorite.

Early Decision FAQ

Is early decision binding?
Yes. If admitted, you enroll and withdraw everywhere else. The financial exception exists, but the college defines what counts as affordable.

Can you apply early decision to more than one school?
Not in the same round. You get one ED I school. If it denies you, you can apply ED II to a different school in January.

When are early decision deadlines for 2026-27?
Most fall on November 1, 2026. Duke, Carnegie Mellon, Tufts, WashU, and UChicago use November 2. ED II deadlines land January 1 through January 4, 2027.

Does early decision increase your chances?
At most selective schools, ED admit rates run three to four times the regular decision rate. Duke admitted 13.8% of ED applicants for the Class of 2030 versus 3.7% in regular decision. Hooked applicants inflate part of that gap.

What happens if you get deferred?
Your application moves to the regular pool for another read. A deferral generally ends the binding commitment, but confirm each school’s policy before acting on that.
