Princeton vs Dartmouth for computer science: how do they compare for undergrad CS strength?

For undergraduate computer science, Princeton is more often viewed as the stronger academic option overall. Its CS department is larger, it offers a broader range of upper-level courses and research areas, and it has especially strong ties to theory, systems, machine learning, and interdisciplinary work through engineering and mathematics. If you want the place where CS feels like a major institutional priority with more depth and scale, Princeton usually has the edge.

Princeton tends to fit the student who wants a highly rigorous, research-heavy environment and expects to be surrounded by a larger concentration of peers deeply focused on technical fields. The department supports serious preparation for both industry and PhD paths, and undergrads benefit from strong access to faculty research, independent work, and a senior thesis culture that can be especially valuable if grad school is on your mind.

Dartmouth makes more sense for the student who wants excellent CS in a smaller, more intimate setting where undergraduate teaching and faculty access are a major part of the appeal. You can still get strong preparation for software engineering, product-oriented roles, and graduate study, but the department is smaller and the menu of advanced electives is not usually as expansive as Princeton's. That matters most if you already know you want niche subfields or want the flexibility to explore many specialized CS areas before deciding.

Dartmouth's quarter-based D-Plan can also be a real advantage for some students because it gives unusual flexibility for off-cycle internships, research, or study away. At the same time, Princeton may feel more seamless if you want a more traditional academic structure and a denser concentration of engineering and math resources around your CS major.

So in pure undergrad CS strength, Princeton gets the nod more often. Dartmouth is still a very strong choice, but it tends to be most appealing when the small-college feel, close faculty relationships, and flexible calendar are central to what you want from college.
