Admissions Process

At Commonwealth, we’re looking for intellectually curious and creative students from a wide range of backgrounds. We encourage you to visit the school, talk with teachers and students, and see whether Commonwealth is the right environment for you.

Request Information: If you are considering admission for the fall of 2021 and beyond, please fill out an online inquiry form. We will send you more information about Commonwealth and keep in touch about future events.

Attend an Open House: Whether you’re still exploring high school options or you’re set on Commonwealth, we urge you to come to an Open House. While it’s not a required part of the process, visiting informally will give you a chance to check out the school before applying.

The application fee is $60 for U.S. residents and $120 for international applicants.
