How should I choose between Columbia Early Decision and Stanford Restrictive Early Action?

The central tradeoff is commitment versus flexibility: Columbia Early Decision can materially strengthen your chances of enrolling at a school you already know you would choose, while Stanford Restrictive Early Action lets you receive an early result without giving up the ability to compare offers in the spring. Columbia ED is binding if admitted, subject to the financial-aid terms being affordable. Stanford REA is nonbinding.

Choose Columbia ED only if Columbia is unequivocally your first choice over Stanford and every other college, and your family has reviewed Columbia’s net price estimate carefully. The binding commitment matters more than any perceived admissions advantage: an ED application says you are prepared to enroll without comparing other admissions outcomes, merit awards, campus visits, or academic options later in the process. Columbia can be particularly compelling if you are drawn to studying in New York City, the Core Curriculum, and its specific undergraduate schools or programs.

Stanford REA makes more sense when Stanford is a top choice but you would genuinely want to weigh Columbia against it, or when cost comparisons will be important. You can still apply regular decision to Columbia after a Stanford REA deferral or denial, and if admitted to Stanford early, you retain time to evaluate your options before committing. Be sure to read Stanford’s current REA rules closely, since they affect which other early applications are permitted.

Based on your wording that both are top choices, Stanford REA is likely the more honest strategic choice unless you can say today that you would enroll at Columbia even if Stanford admitted you. Columbia ED is appropriate only when that answer is an unqualified yes.
