How do undergraduate class sizes compare at Carnegie Mellon and Rice?

Rice is the more consistently small, discussion-oriented undergraduate environment, especially outside introductory courses. Its smaller undergraduate population and residential-college structure create a more intimate campus feel, while Carnegie Mellon’s technical programs often begin with larger, lecture-based foundation courses. Both schools offer small upper-level classes, but Rice is likelier to make that format feel central to everyday academic life.

At Rice, many students encounter seminar-style humanities and social science courses, close faculty interaction, and classes where participation is expected relatively early in their college experience. The residential colleges also mean classmates tend to know one another beyond class, which can make discussions more comfortable and collaborative. STEM courses can still be sizable at the introductory level, but the overall undergraduate scale remains compact.

Carnegie Mellon has excellent access to professors and many specialized, small advanced courses, particularly once students move into a major. However, popular introductory courses in computer science, engineering, business, and science can include large lectures, recitations, labs, and structured problem sets. The classroom culture is often more intensive and project-driven than discussion-driven, with smaller sections providing the main opportunity for interaction.

For a student who learns best by regularly talking through ideas in class, Rice offers the more naturally aligned day-to-day experience. Carnegie Mellon can provide small classes too, but the experience depends more heavily on school, major, and progression beyond the introductory curriculum.
