The short version
The cleanest way to tell them apart is academic philosophy and structure. Williams gives you the most structure among the liberal arts schools — distribution requirements, Oxford-style tutorials, and a January Winter Study term. Amherst gives you a pure open curriculum at a small, self-contained college with four neighbors to draw on. Wesleyan also has an open curriculum, but at a larger university with a distinctive arts and social-engagement culture. Carnegie Mellon is the outlier: a research university where you apply directly into one of seven specialized colleges, trading liberal arts breadth for depth in a chosen field.
The practical splits are large. The three liberal arts schools enroll around 2,000–3,000 and offer a broad, flexible undergraduate education; CMU enrolls nearly 8,000 and is built around specialized professional colleges. Admissions differ in kind, not just degree: Williams and Amherst admit well under 10% through one process, Wesleyan around 16%, while CMU's ~11% overall rate hides enormous variation by college (its computer science school admits under 5%). And on aid, the Little Three are need-blind and largely no-loan, whereas CMU is need-aware. If you're choosing among these, start with the most basic question — do you want a broad liberal arts education or specialized depth? — because it separates CMU from the other three before any number does.
