Does the thought of joining a friendly group of enthusiastic scholars appeal to you? Are you eager to be challenged by teachers who are as warm and supportive as they are passionate academics? Do you want to play—in the band, on the field, or just a game of chess? Would you like to commute to Boston’s Back Bay and have the city right outside your door? Will you join (or lead) the Math Team, Gender-Sexuality Alliance, Debate Team, Robotics Team, or Evil Genius Club? Are you ready to learn what you love and to love what you learn? Think about what you might accomplish here. And take the next step to join us.
Please note that our application deadline for Fall 2025 entry has passed, and we are not accepting additional applications at this time. We would be glad to include you on our email list as we may find ourselves in a position to consider late applicants in the coming months. If you remain interested, we suggest that you contact us in mid- to late-April to learn more.

Commonwealth is definitely a good place for people who want to try new things and want to be challenged, especially in academics but also for arts and even athletics. I think it's a place where you can really be yourself.
