Commonwealth School educates young people from diverse backgrounds to become knowledgeable, thoughtful, and creative adults, capable of careful analysis, fruitful cooperation, responsible leadership, and deep commitment.
It’s an independent high school that feels something like a college and something like a home...
What Makes Us Uncommon?
Catering to curious students who enjoy intellectual adventures in classes often taught at a college level, Commonwealth’s curriculum is rooted in analysis, discussion, inquiry, and writing.
Our small size—about 140 students—and 5:1 student-to-faculty ratio ensure strong relationships and personal attention from our extraordinary faculty.
Two blocks from Copley Square, our Back Bay location gives students unparalleled access to Boston’s resources, fostering meaningful scholarly research, independent projects, and community service.
Every student is paired with an advisor with whom they meet weekly—a teacher who will be a guide, an advocate, a mentor, and a fan.
Our strong community is forged, in part, through unique traditions, like our twice-yearly all-school weekends at a lakeside camp—the setting for some of our most vivid and lasting memories.
With faculty mentors guiding their way, including our dedicated Director of College Counseling, students find themselves empowered and encouraged to follow the post-Commonwealth path that’s right for them.
Art permeates life at Commonwealth, and students choose from a variety of visual and performing arts options each semester—theater, ceramics, chorale, printmaking, orchestra, and more.
Sports are an important route to self-knowledge and pride, which is why we require participation in a variety of engaging athletic options, including fencing, soccer, basketball, and yoga.
Equity and Inclusion
Commonwealth was founded to educate leaders who could bring expertise and empathy to bear on America’s problems, and to make this exceptional education accessible to students from Boston’s racially and socioeconomically diverse neighborhoods. Today, students of color represent nearly half of our enrollment, and the school strives to live up to its founding mission by providing generous financial aid and academic support to ensure all students are prepared to excel.
