How do admissions chances at WashU compare with Princeton for a strong student?

The biggest practical tradeoff is that Princeton is an extreme-reach school for essentially everyone, while WashU, though still highly selective, is a place where a very strong applicant may have somewhat more realistic odds. For a student building a list, that means Princeton should be treated as a high-ambition reach no matter how strong the profile is, whereas WashU can sometimes sit a tier lower, though it is nowhere close to a safety. Both schools attract top students with excellent grades, demanding coursework, and substantial activities, but Princeton’s admissions bar is typically even tighter and more unpredictable.

For a strong student, the difference is less about being “qualified” and more about how many similarly qualified applicants are competing for very few spots. Princeton has one of the most selective applicant pools in the country, and many applicants who look outstanding on paper are still denied. WashU is also very hard to get into, but it is usually viewed as a somewhat more attainable admit than Princeton for students with top academics and a polished application.

That said, WashU is not a fallback in the casual sense. It cares a lot about academic performance, course rigor, and fit with the institution, and many high-achieving applicants are denied there too. In practice, a student who is competitive for Princeton is often also competitive for WashU, but being competitive is not the same as being likely at either school.

When building a college list, I would think of Princeton as a reach that stays a reach regardless of how strong you are. WashU is still best treated cautiously, but for many strong applicants it can be a more plausible reach or high-target-like reach depending on the rest of the profile, school context, and application quality. So your chances are typically better at WashU than at Princeton, but both belong in the selective category and neither should be relied on as a sure admit.
