What GRE score do you need for California Institute of Technology?

There is no single California Institute of Technology GRE cutoff, because programs admit on the whole application and most do not publish a hard minimum. In practice, aim for a score at or above the admitted-student median for your specific program, which some departments share in a class profile or on request. A percentile around the 80th or higher on the section that matters most to your field, Quant for STEM and economics or Verbal for the humanities, is a safe target wherever a score is worth submitting.

Where California Institute of Technology marks a program Optional, a score comfortably above that median can strengthen a borderline application, especially for funded or international applicants. Below it, your effort is usually better spent on the required parts of the file. Where a program is Not accepted, do not send a score, it will not be reviewed.
