Boston College vs. Dartmouth: Which Has Smaller Class Sizes?

Dartmouth generally offers smaller undergraduate classes than Boston College, including a stronger likelihood of small, discussion-centered introductory sections. Its undergraduate-focused structure, relatively small student body, and close faculty access make it particularly well suited to students who want seminars and active participation early in college. Boston College also has many small classes, but its introductory courses are more likely to include larger lecture formats.

At Dartmouth, introductory courses in fields such as economics, psychology, government, and the natural sciences may still use lectures, especially for popular prerequisites. However, those courses commonly pair lectures with smaller discussion sections, labs, or recitations, and Dartmouth’s academic culture places substantial emphasis on faculty-led undergraduate teaching rather than large graduate programs.

Boston College’s Core Curriculum creates a shared liberal-arts experience and includes many discussion-oriented courses, particularly in the humanities and theology. Still, BC enrolls a substantially larger undergraduate population than Dartmouth, so high-demand introductory classes can be larger, with the smallest seminar-style experiences becoming more common after students move into major requirements or upper-level electives.

Dartmouth professors tend to teach a high proportion of undergraduate courses and are embedded in a campus environment built around undergraduates, while Boston College combines strong undergraduate teaching with a larger university setting. For a student prioritizing consistently intimate classes from the first year onward, Dartmouth has the clearer edge.
