The Quaker Testimony of Simplicity reminds us to live wisely and stresses the integrity and development of one's mind, body, and spirit. In an increasingly busy and materialistic world filled with external stimulation, we all need space and time to discern what is truly important in our lives.


Quakers oppose all wars and the violence of oppression. Although disagreement and conflict are inevitable in any group, we work to achieve understanding through respectful dialogue.


Integrity means being truthful and always trying to do our very best. We say what we mean and mean what we say.


We strive to be a welcoming, supportive, and inclusive community in which everyone—students, teachers, staff, and families—feels respected and affirmed.


Quakers have historically emphasized the equality of all people. The belief in "the Light within" has led Quakers to work for peace, prison reform, humane care for the mentally ill, civil rights, and economic justice around the world. In our daily interactions, we work as equals to become a community that welcomes the perspectives of everyone, respects the worth of each individual, and values the collective power of the group.


We need to take care of the things we use and own as well as each other. We believe in leaving the world a better place than we found it.

A private, independent day school in Cambridge, Massachusetts that provides an education guided by Quaker principles for grades Pre-K through 8.
