Four-Year Completion Rate

The graduation rate is among the most important factors when selecting a college.  The California Institute of Technology’s first-year retention rate is 94%. This means that 94% of first-year students continue their education for their sophomore year and beyond. The 4-year graduation rate is 79%. This implies that 79% of students were able to graduate after 4 years. The 6-year graduation rate is 89%. This implies that 89% of students were able to graduate after 6 years.


Student-to-Faculty Ratio

Caltech maintains an exceptional 3:1 student-faculty ratio, fostering a close-knit academic environment that nurtures individual growth and intellectual curiosity. This low student-to-faculty ratio ensures ample opportunities for personalized attention, allowing students to engage in meaningful discussions, receive tailored feedback, and collaborate closely with professors on research projects. This personalized approach to education empowers students to delve deeper into their areas of interest, develop their critical thinking skills, and prepare for success in their chosen STEM fields.

Admissions

 

Acceptance Rate

One-fifth of the admitted students are scholar athletes who will have the opportunity to compete on one or more of the Institute’s Division III varsity athletic teams, demonstrating Caltech’s commitment to fostering a well-rounded educational experience.

Types of Admission

The California Institute of Technology applicants can apply through the Restrictive Early Action, or Regular Decision programs. Restrictive Early Action (REA) is a non-binding early admissions process for students who are confident that Caltech is their first-choice university.  

Students will not be required to accept a Caltech REA offer and may compare financial aid options if they choose to apply to other institutions during the Regular Decision process. Applications are due in November and students will be notified of their admissions decision (admit, defer, or deny) by mid-December. Admitted students will then have until May 1, to decide if they will accept Caltech’s offer of admission.

Students who choose to apply REA to Caltech may not apply Early Action nor Early Decision to any other institution, with the following exceptions:

  • An institution outside of the United States;
  • Any public institution that has a non-binding admissions policy with a fall application deadline (such as the University of California system);
  • An institution’s non-binding rolling admissions process;
  • Any military academy;
  • Any scholarships or special academic programs with an early deadline at another institution, public or private, if the early application submission is a necessary aspect for consideration, and the outcome is non-binding;
  • If you are deferred admission after applying REA to Caltech, you may apply to another institution’s Early Decision II program. If you are admitted to that institution’s Early Decision II program, you are required to withdraw your application of admission to Caltech.

 

Regular Decision is also a non-binding and unrestrictive admission plan that allows students more time to complete the application and to have grades from the first term of their senior year considered in the review.
