Colby vs Tufts for international relations: which is better for an IR major?

For international relations specifically, Tufts has the clearer edge in both reputation and built-in opportunities. Its political science and international affairs ecosystem is unusually strong for an undergraduate-focused university, and being next to Boston gives students easier access to internships, speakers, research centers, and globally oriented organizations during the school year.

Tufts tends to fit the student who already knows they want IR to be a central part of college. It has a long-standing reputation in international affairs, strong language study, globally focused coursework, and close ties to policy and diplomacy through its broader academic network. Even as an undergraduate, you benefit from being at a school where international issues are a major intellectual priority rather than just one strong option among many.

Colby makes more sense for a student who wants a liberal arts college experience first and an IR-related path within that setting second. You would get smaller classes, close faculty relationships, and solid interdisciplinary work in government, global studies, economics, history, and languages. Colby can be excellent for someone who wants to study international topics in a more intimate academic environment, especially if they value a residential campus culture and less of a pre-professional atmosphere.

In terms of overall reputation for IR, Tufts is the name that will more immediately register with people in that field.

Colby is not a weak choice, but its strength is broader undergraduate liberal arts education rather than being especially known for international relations in the way Tufts is. If your question is specifically which school is stronger for IR as a major and for related opportunities, Tufts is the more compelling option.
