Princeton need not decrease the rigor of its classes — or change them at all — for students who are less prepared. Instead, Princeton can follow the lead of the Massachusetts Institute of Technology and aim to admit a cohort of students who are fully prepared from day one. MIT accomplishes this through a mandatory standardized test requirement, which, in the words of their dean of admissions, [7] “significantly” improves the school’s ability to predict academic success (MIT’s emphasis, not mine).
