Application Deadlines

Caltech offers two rounds of admission: Early Action and Regular Decision.

Early Action

Early Action is non-binding and non-restrictive. If you apply to Caltech during Early Action, you can apply to as many other schools as you wish as long as you are not violating their policies. You are not required to attend Caltech if you are accepted during the Early Action round.

Potential outcomes from Early Action include: accept, deny, and defer. If you are accepted in Early Action, you are not obligated to attend Caltech. You have until May 1 to give us your matriculation response. If you are denied in Early Action, you may not reapply during Regular Decision. If you are deferred in Early Action, you may opt-in to be reconsidered during Regular Decision. You will be given the opportunity to send in supplemental materials to support your application.

Regular Decision

Potential outcomes from Regular Decision include: accept, deny, and waitlist. If you are accepted in Regular Decision, you have until May 1 to give us your matriculation response. If you are denied in Regular Decision, there is no appeals process. You may reapply for the next fall entry term if you wish. If you are waitlisted in Regular Decision, you may opt-in to be reconsidered should space become available in the class after May 1. You will be given the opportunity to send in supplemental materials to support your application.
