What minimum GRE score requires for admission at caltech?

Caltech doesn't publish minimum GRE scores for admission. They consider the GRE (if submitted) as *one* factor among many in a holistic review process. A high GRE score won't guarantee admission, and a lower score doesn't automatically disqualify an applicant. Their admissions decisions are based on a comprehensive evaluation of the applicant's academic record, research experience, letters of recommendation, statement of purpose, and other qualifications. Focusing solely on a minimum score is misleading and unproductive.
