Dorms are comfortable and cozy. More than 70 dormitory heads and affiliates are there not only to supervise, but to guide and support.
Since the earliest days of the School, Groton has ended its day with handshaking. The Rector and Mrs. Peabody began the tradition as they said good night to each student . Now, over 100 years later, the day at Groton ends in much the same way, with each student shaking the hand of his or her dorm head. The tradition builds a sense of community, just as it did more than a century ago. There are now 17 dormitories; handshaking happens in every one, every night.
Second and third form students live with members of their own form; all dorms are separated by gender. Lower School dormitories feature a special layout, which provides each student with an individual bedroom, separated from his or her cube-mate's bedroom by a study. Cubes have only partial walls and open onto a common area, providing students with privacy while fostering close relationships with other members of the form. Students learn from the diversity of other students' backgrounds while developing a sense of form unity and identity. Second and third form students become accustomed to routines regarding lights-out and evening study hall, which, as they become fourth, fifth, and sixth form students, become habits rather than enforced rules.
Upper School dormitories house fourth, fifth, and sixth formers in more traditional, collegiate-style dormitories. Fifteen to 23 students live in single, double, or triple rooms and share large living rooms, which adjoin the resident faculty apartments. The common rooms are comfortably furnished, provide kitchen facilities, and often have fireplaces. Students and the faculty resident together organize life in their own dormitories, planning everything from daily maintenance to fun activities. By Upper School, structures and routines developed in the second and third forms have become engrained, and fifth and sixth form students manage their own time with almost complete independence, a good preparation for college.
