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.

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.

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.

Recess—Commonwealth’s daily all-school meeting—is a keystone, a constant, a simple pleasure, and something we hadn't experienced fully in person since March 2020. That is, until now.
Three Commonwealth alumni/ae turn a lens on their time in media—from television to indie films to documentaries—and find an increase in diversity and complexity of stories within the industry.
