Notre Dame vs Columbia for undergraduate teaching: which school is better for class size and professor access?

The biggest practical tradeoff is this: Notre Dame is built much more around the undergraduate experience, while Columbia gives you access to an extraordinary research university in a setting where undergrads can sometimes feel like one group among many. For class size and professor access, Notre Dame usually has the clearer advantage day to day. Columbia absolutely has outstanding faculty, but the teaching experience can feel less intimate, especially in the Core and in popular introductory courses.

At Notre Dame, undergraduates are the center of the institution in a way that is hard to miss. It is primarily an undergraduate-focused university, so advising, residential life, and classroom culture tend to be designed with undergrads in mind first. Students often describe professors as accessible, invested, and easier to build ongoing relationships with, both because of the school’s culture and because there is less of the large urban research-university feeling.

At Columbia, you get world-class professors and the intellectual energy of a major research institution in New York, but that comes with more variation. Some classes, especially seminars and upper-level courses, can be excellent for discussion and faculty contact. But introductory classes may be larger, and some students feel they need to be more proactive to stand out, attend office hours, and form real relationships with professors.

The Core Curriculum does help Columbia undergrads in one important way: it creates a shared academic experience and includes discussion-based classes that can be quite engaging. Still, that does not fully cancel out the fact that Columbia’s overall environment is more graduate- and research-intensive than Notre Dame’s.

If your main question is specifically undergraduate teaching quality as experienced through smaller classes, easier professor access, and feeling supported in the classroom, Notre Dame is the stronger pick. Columbia can be exceptional for a self-starting student who wants the resources and pace of a major research university, but Notre Dame is more consistently aligned with the kind of close-knit teaching experience you’re describing.
