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.

Commonwealth attracts a great mix of students that I've made a lot of strong connections with. In that area, it was much easier for me than I expected to feel comfortable going up and talking to new people, since everyone is getting to know each other the same way you are.

Whether teaching economics, calculus, or geometry, Rob Sherry makes a lasting impact on his students. He has maintained his calm analytical approach throughout the pandemic and hybrid learning as well—ensuring that all of his students feel engaged and excited to learn.


“Debate, 4:30, Pérez.” Such is Miles’s wonderfully pointed and predictable refrain in recess, a glimpse of his efficient, effective leadership on the Debate Team and indicator of his precise way of examining the world, whether it’s noticing the absorption spectra of stained glass or when the temperature of a wood stove is in a state of equilibrium. Get to know this Commonwealth junior from Westwood, Massachusetts, who relishes challenge, whether he finds it in the classroom or on the debate stage.

A jury has found Derek Chauvin guilty of the murder of George Floyd, and with this verdict, a collective national tension seems to have eased. Yet, a single verdict does not change these fundamental inequities. A single verdict does not eliminate bad policing. But it is accountability, a step that gives some hope.

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.
