All incoming undergraduates are assigned to one of Yale’s fourteen residential colleges. Students remain affiliated with their residential college for all four years (and beyond). Yale makes every effort to represent the diversity of the entire undergraduate community within every residential college. In this sense, each college is a microcosm of the larger student population.
Most first-years reside on Old Campus in dormitories designated to specific colleges. Students live in their colleges starting sophomore year. The exceptions are Silliman, Timothy Dwight, Benjamin Franklin, and Pauli Murray Colleges, where students live in the college proper from their first year.
