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. Bowdoin sits in between, with a first-year writing seminar and five light distribution areas, on a coastal-Maine campus built around the outdoors. Hamilton is the open curriculum with one string attached: you choose nearly everything, but you must take three writing-intensive courses, part of a college-wide emphasis on writing and speaking. The two technical universities trade that breadth for depth: Carnegie Mellon admits you directly into one of seven specialized colleges, and RPI asks you to pick one of five schools and then requires a term of real-world work — an internship, co-op, or research placement — before you can graduate.
The practical splits are large. The five liberal arts colleges enroll roughly 1,900–3,200 and offer a broad, flexible undergraduate education; CMU enrolls nearly 8,000 and RPI about 5,700, both built around specialized schools. Admissions differ in kind, not just degree: Bowdoin, Amherst, and Williams admit well under 10% through one process, Hamilton around 13.5% and Wesleyan around 16%, while CMU's ~11% overall rate hides enormous variation by college (its computer science school admits under 5%) and RPI is far more open on paper, admitting roughly 63% of a self-selecting technical applicant pool. Aid works differently too: the liberal arts colleges are need-blind for domestic applicants and meet full need — several with no loans — whereas CMU is need-aware and RPI leans on large merit scholarships rather than a meet-full-need pledge. If you're choosing among these, start with the most basic question — do you want a broad liberal arts education or specialized technical depth? — because it splits the set in two before any number does.
