Secondary School Report
This is a document that is sent to Caltech by your high school college counselor. It provides context about your school that helps the Admissions Committee evaluate your application holistically.
Additional requirements of our international citizen applicants:
TOEFL scores: Required of all international citizens unless 1) your native language is English or 2) you have studied for two or more years in a school where English is the language of instruction. The latter must be completed prior to the application deadline. We do not accept the IELTS or any other substitute for the TOEFL requirement.
International Financial Aid Statement of Intent: When an international citizen applies for freshman admission, the application prompts questions to confirm their understanding of our financial aid policy and thus confirm their financial aid intent towards Caltech. Caltech is need-sensitive for international citizens because the total amount of financial aid funds is limited for these students, and we remain committed to meeting the demonstrated need of all admitted students
Three letters of recommendation - Recommendation letters should address the following information:

motivation to be successful as a student at Caltech?

If English is not the native language, how well does the applicant read, write, and converse in English?
How does the applicant compare to any previous students who have come to Caltech for their graduate work?
Statement of purpose - brief statement of your scientific and professional interests and objectives. Include a description of your past accomplishments that are not evident from the examination of other documents submitted.
