Caltech typically enrolls 235 outstanding freshmen each fall term. Students who have not yet earned a high school diploma (including students enrolled in high school/college dual enrollment programs) or who have not enrolled in college courses for credit after graduating from high school will be considered as freshman candidates.
November 1, 2013: Early Action
January 3, 2014: Regular Decision
Applying Early Action or Regular Decision?
Students should consider applying Early Action if they can demonstrate strong academic preparation and achievement without benefit of senior-year first semester grades, have taken all the required SAT and ACT tests by the October test date.
Applicants will be notified by mid-December whether they have been admitted, denied or held for review during the Regular Decision process. There is no strategic advantage to applying Early Action; it is non-binding in that the candidates who are admitted early need not respond to the offer of admission until May 1.

Credit for Advanced Placement, International Baccalaureate or College Courses:
Caltech does not grant credit for AP, IB, or college courses taken prior to enrollment. Each student will take a math and physics placement exam prior to enrolling. Based on the results of these exams, a student may place out of courses and be granted credit for those courses.
In some cases, Caltech faculty will grant permission to take a higher level course in other disciplines based on an evaluation of previous preparation in that discipline. These decisions are made on an individual basis after a student enrolls at Caltech.
