Uncommon Opportunity

Commonwealth is a co-ed independent day school welcoming curious, highly motivated students in grades 9–12. Our close-knit community thrives on making meaningful intellectual and personal connections, while tapping into the opportunities surrounding our home in Boston’s Back Bay.

Meet Faculty and Students

Commonwealth taught me how to interact with different people, and I think I've learned a lot of skills regarding meeting new people.  It's having that safe space, where I can make myself uncomfortable, but I also have my advisor and I have friends who support me.

It is humbling and exhilarating to come to work every day to a place where people are working for a common goal with such a mix of competence and humanity.

I was first interested in Commonwealth by the small class sizes and the very rigorous environment. Visiting and having a virtual class was what drew me in. I'm very happy about making the choice to come here. The classes are intriguing, to say the least. There is difficulty but nothing I can’t handle. And the opportunities, such as Project Week, are unique, and they allow us to develop our own interests.

My students teach me so much that each subsequent year the course is informed by their insights.

Melissa Glenn Haber '87, History

I get a real burst of energy when I’m able to help students navigate the complexities of the research process. I feel so lucky to have such an incredible patron base of high-level readers and thinkers in our students. 

Jake MacDonnell, Librarian and Registrar

Classes have been absolutely amazing. The teachers here really care about what they’re teaching, and that makes all the difference.

I love the campus, too—you know, Boston is the campus in a sense. That’s what they told us when we visited, and that’s really been delivered. You can just hop on the T at Copley or at Back Bay and go anywhere. I can walk across a bridge over the Charles River and be at MIT or Kendall Square, or walk a few blocks and be in Beacon Hill. I think it's just so rewarding to have that freedom.

Happening Now

Jennifer Borman and Rebecca Jackman stand outside of Jennifer's office, facing the camera and smiling. In between them is the open door to the office.

Jennifer Borman '81 and Rebecca Jackman don't do small talk—they're constantly conversing about how to balance long-term planning with day-to-day classroom management, the art of finding extraordinary teachers, and what it means to be a young adult today. Listen in on some of their ongoing discussions...

history-research-paper-searching-for-lost-generation

Our annual history research paper challenges students to dig deep into a variety of sources on any topic of interest—like this recent example from Ava '23, examining how a generation of writers, seemingly “lost” in the wake of the tumult of the early twentieth century, perhaps knew just where they were going...

Commonwealth alumna Cora Kraft sits on a park bench wearing a black dress, looking downwards at a camera in her hands and laughing.

Photo editor and culture critic Cora Kraft ’09 has been featured in The New Yorker and New York Times—and her time at Commonwealth helped her realize that art and writing would be inseparable in her work. "Every time I've tried to focus just on one," she says, "I've missed the other." Discover what she's been up to since her visual arts and English classes...

Sofia has known about Commonwealth for as long as she can remember—quite literally. And when Commonwealth launched Dive In in 2019, Sofia and her family were among the first to know. After two summers of Dive In, she ultimately decided to enroll in Commonwealth for high school, too. Both decisions brought their own surprises along the way.

At Commonwealth, we’re looking for inquisitive, driven, and creative students from a wide range of backgrounds. We encourage you to visit us, talk with teachers and students, and see if Commonwealth is right for you.
