A brief description of a few NESCAC and non-NESCAC colleges, based on my opinion:
In the NESCAC
Williams: Refuses to apologize for its isolated location – a good thing. Has an impressive senior tutorial program. Benefits from a strong national reputation.
Amherst: Consortium creates some interesting academic options, but the area consequently also suffers from a collegiate gender imbalance. An excellent school academically that also benefits from a strong national reputation.
Hamilton: Benefits from the curricular, architectural, spatial and, to some extent, cultural legacy of having been two colleges. A balanced curriculum, but also a writers’ college. Former fraternity houses are now beautiful residence halls.
Wesleyan: Progressive. Good vegan food. The recent publicity regarding drug usage is difficult to interpret evenly. Regardless, an excellent school academically with interesting alumni.
Colby: Classic LAC size. If you go much smaller than this (consortia excepted), you will sacrifice either athletics or curricular breadth; much larger, and you will lose the LAC feel. Has the coldest winters in the NESCAC.
Bates: A long history of progressivism may positively affect the social climate on campus to this day.
Trinity: The Long Walk is cool. Urban distinction with associated benefits and drawbacks. Alumni seem to care more about their fraternities than their college.
Outside the NESCAC
Colgate: One of the most beautiful campuses in the nation. Colgate’s town has been rated as one of America’s friendliest, according to Forbes.
Vassar: English major/artsy vibe, recently offset by their investment in an impressive new science building. Beautiful chapel and library. The gender imbalance, though real, does not differ significantly from the national average.
St. Lawrence: Whichever direction you travel you will find something interesting: the protected Adirondack Park, the Thousand Islands, Canada.
