Mission statement: Groton School is a diverse and intimate community devoted to inspiring lives of character, learning, leadership, and service.
Motto: Cui Servire Est Regnare (For Whom Service Is Perfect Freedom)
Groton history suggests that the School had two earlier mottos: Esse Quam Videri (To Be Rather Than To Seem) and the lesser-known Deo Magistro Semper Condiscipuli (Forever Fellow-learners, God, Our Master, Blessing). Cui Servire Est Regnare, derived from the Book of Common Prayer, has been in place since the turn of the 20th century. In the motto's original context, service referred to a person's service to God. But the motto has been accepted more broadly to connote service to the community and the world, and it inspires many Grotonians to make community service integral to their lives.
