<p>There are many similarities in ambience and student type. Lively intelligent extroverted kids. Rigorous academics. Tight knit community. Prevalence of sports and outdoorsy activities.</p>
<p>Dartmouth is bigger and has graduate/professional schools including business, engineering and medicine (4200 undergraduates, 1200 graduates). Williams is smaller (2000 students) and is mostly undergraduate, except for a small art history masters program. I'd say that Williams has a stronger focus on the arts -- fine art/museums, performing arts like theater, dance, music, but both offer a lot by the way of campus activities. Dartmouth has fraternities/sororities; Williams doesn't. Other points of differentiation at Williams are the firstyear entry system, the tutorial program and Winter Study. Dartmouth has the Dartmouth Plan.</p>
