Tuition and Financial Aid

Since our founding, we have been dedicated to increasing access and welcoming as many qualified students as possible. Our need-based financial aid program empowers us to attract strong applicants from a wide range of backgrounds and to compose a well-rounded and talented student body. To that end, we are committed to partnering with families to meet the cost of a Commonwealth education.

Financial Aid Grants and More

Commonwealth’s financial aid includes textbooks, all-school trips, participation in clubs and activities, and, in many cases, public transportation. We also offer discounted standardized testing, test preparation, and tutoring, and we extend additional grants for summer programs and school-sponsored international trips. For the 2022–2023 school year, Commonwealth also extended $10,000 in additional technology grants to eligible families for purchasing a MacBook Pro laptop, printer, and software at a reduced cost. On average, participants paid $215 for this package.
Families of returning students can find additional financial aid information on the Parent Portal (login required).
