All MIT freshman undergraduate students (except a very small number who commute from Boston-area homes) are required to live in an MIT dormitory during their first year of study. Each MIT dormitory has its own history, traditions, and student culture. Both undergrad and grad dorms have a resident Housemaster, usually a member of the MIT faculty, living in a special apartment suite within the building. Some of the larger dorms have multiple Housemasters, each responsible for a subsection of the building, and consulting together on building-wide issues. Undergrad dorms are usually divided into suites or floors, and usually have a Graduate Resident Tutor (GRT), a grad student living among the undergrads who is supposed to help support student morale and group activities.
