Graduate programs in research-intensive institutions like Caltech provide some classroom education, but the majority of the experience is centered around learning through working on an open-ended problem, with the goal of developing the ability to independently formulate and carry out a research program. Graduate students spend the majority of their time in small research groups or individually working with faculty advisors.
Admission to Caltech graduate study is highly competitive. The faculty review all the materials in the application to make a decision; they evaluate many factors including academic preparation, experience and research interests, recommendations from teachers/mentors, and they look for a match between faculty and an applicant's research interests.
The application deadlines vary by department and range from November 21 to January 1. Please refer to our Application Deadlines document. Applications received after the posted deadline may be considered, but late applicants may be at a disadvantage in terms of being admitted and/or in the allocation of financial aid. Caltech conducts admissions once each year and applicants are considered for admission to the fall term only.
Caltech admits students for the fall term only. Applications are not considered for the winter, spring and summer terms.
Each academic option has a different schedule for considering applications and offers of admission will be made as the faculty make decisions on individual applications. Applicants may be notified at any time in the period between the deadline for submission and April 1. Offers are made as soon as possible so that students will have a chance to consider graduate study at Caltech together with opportunities at other institutions.
Most academic options host visit days in order for select applicants to learn more about the program, the campus, and community prior to making their decision. The arrangements and schedule for visit days are set by the individual options, and each option will work with selected applicants and faculty to coordinate visits. When in person visits are not feasible, online interviews may also be conducted.
In general, most graduate students at Caltech receive full funding for their graduate education. In fact, all doctoral students have full financial support in the form of internal or external fellowships, research assistantships, teaching assistantships, or some combination of fellowship and assistantship support. Most of the funding sources require work authorization. As a consequence, matriculation into the PhD program requires evidence of work authorization, unless special compensation can be arranged with the admitting option. In most cases financial assistance is awarded on an annual basis and is dependent upon satisfactory academic progress. A separate application for requesting financial aid is not required.
For additional questions or assistance related to financial aid, please contact the Graduate Studies Office.
Inquiries regarding loans should be directed to the Office of Financial Aid.
On average, more than 98% of graduate students offered admission at Caltech are offered a package of merit-based financial support that pays all tuition charges and provides them with a stipend. The only major exception is the case of students in terminal master's programs, who in many cases are self-supported or who have a financial sponsor. These students should refer to the information on financing a graduate education.
Financial support includes research and teaching assistantships, Institute fellowships, and external fellowships. Most of the funding sources require work authorization. As a consequence, matriculation into the PhD program requires evidence of work authorization, unless special compensation can be arranged with the admitting option. For additional information on the various funding sources, please refer to Financial Support.
GRE policies differ substantially among the various graduate programs, and therefore applicants must review the GRE policy for their specific graduate program.
Caltech does not have a minimum GPA requirement. However, most successful applicants have a US GPA of at least 3.5 on a 4.0 scale and/or are in the top 5 to 10% of their class.
GPA's should only be reported for those schools attended within the United States. International GPA's or rankings should not be converted to the standard US grade point average.
Applicants whose first or native language is not English are asked to demonstrate English proficiency as part of the application procedure. Caltech recognizes scores from the Educational Testing Service (ETS) (www.toefl.org), Pearson's Test of English Academic (PTE) (www.pearsonvue.com/pte), and from the Cambridge Examinations and International English Language Testing System (IELTS) (www.ielts.org).
The following exemptions apply:
Please note that regardless of any documentation of English proficiency submitted as part of the admissions process, all non-native English speakers who have not attended a school where English is the primary language of instruction will be screened prior to enrollment and may be required to take additional English as a Second Language (ESL) courses.
There is no minimum requirement for the English proficiency exams. However, all new students who have had limited instruction in English will participate in a one-on-one English evaluation with the ESL instructor during Orientation and may be asked to enroll in an English as a Second Language (ESL) course.
Three letters of recommendation are required.
The online application currently accepts three letters maximum, so keep in mind that it's important to submit three strong letters from individuals most familiar with you.
Letters should be requested from those individuals who know you best and can attest to your academic capabilities or training. While faculty members and research supervisors can provide the strongest academic recommendations, we recognize that some applicants may also have work experience that relates to their abilities and training. Keep in mind that those individuals writing recommendation letters should be able to address the following information:
Yes, individuals unable to submit materials electronically may send materials to:
Graduate Studies Office, Mail Code 230-87, California Institute of Technology, 1200 E. California Boulevard, Pasadena, CA 91125; or Email gradofc@caltech.edu
Be sure that the applicant's name is clearly indicated on any supporting documents not submitted with the application.
The Graduate Admissions Committees recognize that applicants enrolled during the spring term 2020 and beyond may pursue pass/fail or other non-standard grading options, and applicants will not be asked to notate or document these changes to the grading system on submitted transcripts.
The most recent transcripts available should be uploaded with the application form. Grade reports for additional terms are not needed for application purposes and once the application is submitted, you will not be able to submit updated transcripts. Official, sealed transcripts documenting attendance and all degrees conferred at each college or university will be required for admitted students prior to enrollment.
For the purpose of applying, unofficial and scanned copies of an original transcript or university generated web printouts are accepted. Please note, however, that any electronic submissions must be unofficial records from the university or college attended. Hand-typed listings of courses prepared by the applicant will not be considered. Official transcripts documenting attendance and the degree awarded at each college or university will be required for admitted students prior to enrollment.
One copy of your transcript from each college or university attended is required.
Very few departments admit directly for the Master of Science degree. Currently, only applicants to Aeronautics, Electrical Engineering, and Space Engineering may apply for a terminal Master's degree. All other departments admit for the PhD degree only.
Applications will not be accepted for more than one academic option per admission cycle. In reviewing your application, the admission committee of the option to which you have applied may recommend that your application be reviewed by another option. If your application is referred to another option you will not be charged any additional fees or be asked to submit a duplicate application.
The fee waiver request form is included as part of the online application under payment options. In order to demonstrate financial hardship, applicants requesting a fee waiver will be asked to provide earned income and expenses and explain any circumstances that impact their ability to pay the application fee. Once an application is submitted, fee waiver requests will be individually reviewed, and decisions will be sent through the online admissions system. If a fee waiver is not granted, applicants will have the opportunity to submit additional documentation for further review demonstrating financial hardship or submit payment.
Once the application has been submitted, you will not be able to modify supporting documents, so please proofread your materials thoroughly before submission. If there is a major error in your application, please contact the Graduate Studies Office (gradofc@caltech.edu) for instructions.
