REA is the best of both worlds for students whose first choice is Harvard, Yale, Princeton, or Stanford — early answer, no binding commitment, and preserved options.
What REA Is
Restrictive Early Action (sometimes called Single-Choice Early Action, or SCEA) combines the timing advantage of applying early with the non-binding flexibility of EA. You apply by November 1, receive your decision in mid-December, and are under no obligation to enroll — you can compare all financial aid packages and make your final decision by May 1.
The Restriction
The restriction: while your REA application is pending, you may not apply Early Decision or Early Action to other private schools. You can still apply Regular Decision to as many schools as you like. And you can apply Early Action to any public universities — UC schools, University of Michigan (EA option), UVA, University of North Carolina, etc. The restriction applies to private school EA/ED simultaneously, not to all early applications.
The Strategic Approach
For students applying REA to one of the four schools, the optimal strategy is: apply REA in November, apply EA to public university options simultaneously (if available), and apply Regular Decision to all other private schools. This maximizes early options while preserving flexibility.
