ED2 / EA / REA / RD Deadline Overview: Key December Milestones for the 2026 Application Cycle
Published on March 19, 2026
Which of the five application rounds, ED / ED2 / EA / REA / RD, should you use or avoid? What do Binding and Non-Binding mean? The key November, December, and January milestones are all covered here, with a real Yale REA + Cornell RD combination broken down step by step.
ED2 / EA / REA / RD Deadline Overview: Key December Milestones for the 2026 Application Cycle
Published on May 14, 2026
Every October, the most anxious message I receive from parents is: "Teacher, my son wants to apply Yale REA, but he also wants to apply Cornell ED. Is that allowed?"
My answer is always: "Yale REA is Restrictive Early Action, so you cannot apply to another private ED/REA school at the same time. Cornell ED is binding, which means if you are admitted, you must withdraw Yale. You can only choose one of the two."
Parents get even more anxious: "Then what if he does not get into either?"
The answer is: Choosing between ED and REA is itself a tactical question of maximizing admission probability. Choosing the right ED school can double your admission chances. In this article, I use 15 years of hands-on experience to break down every detail of the four application rounds.
1. The Core Differences Among the 5 Application Rounds
Round
Full Name
Binding?
Application Limit
Typical Deadline
Results Released
ED
Early Decision
Binding (must enroll if admitted)
Only 1 school
11/1
12/15
ED2
Early Decision Round 2
Binding (same as above)
Only 1 school
1/1-1/15
2/15
EA
Early Action
Non-Binding
No limit (most schools)
11/1-11/15
12/15
REA
Restrictive Early Action
Non-Binding
Limited to 1 school (same type of private school)
11/1
12/15
RD
Regular Decision
Non-Binding
No limit
1/1-1/15
3/15-4/1
Binding: If you are admitted, you are required to attend, and you must withdraw all other applications. Non-Binding: After being admitted, you may still choose whether to attend.
2. The Real Advantages and Conditions of ED
2.1 Why Is the ED Admission Rate Higher?
The ED admission rate is usually 2-3 times higher than RD:
School
ED Admission Rate
RD Admission Rate
Multiple
Brown
13%
4%
3.3x
Cornell
15%
7%
2.1x
Dartmouth
19%
5%
3.8x
Duke
21%
4%
5.2x
Vanderbilt
19%
5%
3.8x
Northwestern
25%
5%
5.0x
Columbia
11%
3%
3.7x
UPenn
17%
5%
3.4x
Why?
There are fewer ED applicants (most students reserve ED for their dream school)
ED applicants have 100% yield (if admitted, they must come), and schools care deeply about yield
Legacy applicants usually apply ED
Recruited athletes usually apply ED
2.2 The Condition for ED: You Must Be Able to Afford Tuition
The real trap of binding: After an ED admission, you must attend, regardless of tuition cost.
Scenario
Consequence
Admitted ED, and tuition is affordable
You must attend and withdraw all other applications
Admitted ED, but financial aid is not enough to afford attendance
You may appeal for financial hardship to be released from the ED commitment
Admitted ED, but you regret it and want to attend Stanford RD
The school may notify Stanford that you broke the agreement, which could damage all your applications
The truth: ED is suitable for students who can afford the cost and are 100% certain about their dream school.
2.3 Special Considerations for International Students Applying ED
International students should note the following about ED:
After being admitted ED, you can still apply for financial aid, but many schools are Need-Aware in ED, meaning your family income may affect the admission decision
Some schools, such as Yale, do not allow international students to apply ED and financial aid at the same time. You must decide first whether you will request aid
3. What Is ED2? When Should You Use It?
ED2 is a "second ED" round. It usually has a 1/1 or 1/15 deadline, with results released around 2/15.
3.1 ED2 Scenarios
Typical situation:
You applied to Brown in ED Round 1 and were rejected on 12/15
On 1/1, you can still apply ED2 to another school, such as Vanderbilt
Results are released on 2/15
3.2 Which Schools Offer ED2?
School
ED2 Deadline
Vanderbilt
1/1
WUSTL
1/2
Carnegie Mellon
1/3
Tufts
1/4
NYU
1/1
Boston College
1/1
Northeastern
1/1
Emory
1/1
University of Chicago
1/2
Do not offer ED2: Harvard, Yale, Princeton, Stanford, MIT, Brown, Columbia, UPenn, Cornell, Dartmouth
3.3 The Tactical Value of ED2
ED2 admission rates are still higher than RD:
School
ED2 Admission Rate
RD Admission Rate
Vanderbilt ED2
14%
5%
NYU ED2
28%
14%
WUSTL ED2
13%
6%
Conclusion: After being rejected in ED Round 1, ED2 is your final chance to trade binding commitment for a higher admission rate again.
4. EA: The Most Flexible Early Round
4.1 Features of EA
Non-Binding: You may choose not to attend after being admitted
You can apply to multiple EA schools at the same time (except REA schools)
Deadlines are usually 11/1-11/15
Results are released around 12/15
4.2 Which Schools Offer EA?
School
EA Type
MIT
EA (no ED)
Caltech
EA
University of Chicago
EA
Georgetown
EA
Boston College
EA
Notre Dame
EA
Tulane
EA
Northeastern
EA
Public universities (UMich, UNC, UVA, UGa, UMass)
EA
4.3 The Tactical Value of EA
EA admission rate vs RD admission rate:
School
EA Admission Rate
RD Admission Rate
MIT
5%
4%
Caltech
6%
3%
Georgetown
12%
12% (about the same)
Chicago
9%
5%
Public universities
Usually similar to or slightly higher than RD
Conclusion: EA's admission-rate advantage is much smaller than ED's. At most schools, the EA and RD admission-rate difference is under 2%. But EA has one key value: you know the result early, around 12/15, allowing you to adjust your later strategy.
5. REA: The Special Round Used by Yale / Stanford / Harvard
5.1 What Is REA?
REA = Restrictive Early Action:
Non-Binding: You may choose not to attend after being admitted
Limited to 1 school: After applying to one REA school, you cannot simultaneously apply to another private ED/REA school
You may still apply to public EA schools: UMich, UVA, and UNC are allowed
Deadline: 11/1
Results released: 12/15
5.2 Which Schools Use REA?
Only 4 schools:
School
REA Naming / Usage
Harvard
Single-Choice Early Action (same as REA)
Yale
Restrictive Early Action
Stanford
Restrictive Early Action
Princeton
Single-Choice Early Action
5.3 REA's "Forbidden Combinations"
After applying Yale REA, you cannot apply to:
❌ Any REA at Harvard / Princeton / Stanford
❌ Any ED at Brown / Columbia / UPenn / Cornell / Dartmouth
❌ Any ED at Duke / Northwestern / Vanderbilt / WUSTL
❌ Any ED at NYU / BC / Tufts / Emory
After applying Yale REA, you can apply to:
✓ MIT EA, Caltech EA, Chicago EA, Georgetown EA, Notre Dame EA
✓ Public university EA (UMich, UVA, UNC, etc.)
✓ RD at all schools (such as Stanford RD and Princeton RD)
5.4 REA Admission Rates
School
REA Admission Rate
RD Admission Rate
Harvard SCEA
9%
3%
Yale REA
11%
5%
Princeton SCEA
14%
5%
Stanford REA
8%
4%
REA admission rates are lower than ED because REA is non-binding, so schools gain less yield benefit. But REA is still 2-3 times higher than RD.
6. RD: The Final Round Everyone Uses
RD (Regular Decision) is the main round accepted by all schools.
Item
Details
Deadline
1/1 (most schools), 1/2, 1/15, 2/1
Non-Binding
You may choose not to attend after being admitted
Number of applications
No limit
Results released
3/15-4/1
Enrollment decision deadline
5/1 nationwide (National College Decision Day)
The truth: RD has the lowest admission rate (3-7%), but everyone applies RD. RD is the "baseline safety strategy."

9. Differences in Common App Activities Across Application Rounds
Note: The ED deadline is 11/1, but activities you completed during the summer after Grade 11 or in September can still be added. You can update Activities until you submit the ED application.
Action Before the Deadline
Impact
Update PS / Activities before ED 11/1
✓ Sent to ED schools
Update PS / Activities after ED 11/2
❌ ED schools will not see it; only RD schools are affected
New achievements in Grade 12
Send them through an "Update Letter"
10. Defer / Waitlist: What to Do After Early Applications
ED / REA / EA outcomes may fall into 3 categories:
Result
Meaning
Next Step
Admit
Admitted
ED: must attend; REA/EA: optional
Reject
Rejected
Apply to other RD / ED2 schools
Defer
Deferred review: your application enters the RD pool
Reassess RD strategy and strengthen your Update Letter
Strategy after a defer:
Write an Update Letter to the deferring school: include new achievements and progress on other applications
Resubmit EC updates
Ask your Counselor to write a follow-up letter

12. Conclusion: Early Applications Are Strategy, Not Luck
Over the past 15 years, I have seen too many parents treat early applications as one more chance. That is wrong. Early application is not a chance; it is a strategic choice.
My final reminder to Dr. G. students:
ED is for students with a dream school and affordable tuition; REA is for students whose first choice is one of HYPS; EA is for students who want to know public university results early.
Choosing the wrong early application combination means wasting a precious ticket to an admission rate that is 2-3 times higher.
You should choose your first ED / REA school by June of Grade 11. If you wait until September to decide, you have already fallen behind other applicants.
