Some engineering schools require students seeking admission submit SAT Math 2 subject test results in addition to a science (Bio, Chem or Physics) SAT subject test. Does Santa Clara University have such a requirement?
They do not require subject tests, and not for engineering either, to be specific.
See section C of Common Data Set for Santa Clara for admissions requirements. Section C8 specifically covers which standardized tests are required,

FYI, you can google “Common Data Set <>” for any school.
