Beyond a general absence of curricular requirements, “open” also suggests an academic structure and culture in which most courses have been made available to most students. Even schools with some distribution requirements may encourage student freedom in course selection to an uncommon degree. Conversely, a college that appears relatively open may restrict access to courses in popular departments such as film. Smith, Grinnell, Amherst and Hamilton would seem to be supportive of academic exploration under virtually all scenarios.
