Tuition and Financial Aid

Since our founding, Commonwealth School has been dedicated to increasing access and welcoming as many qualified students as possible through extensive need-based financial aid. Making tuition more affordable and within budget for our families continues to be an institutional priority. This empowers us to attract strong applicants from a wide range of backgrounds and to compose a well-rounded and talented student body.

We’ve been incredibly grateful for the financial aid Commonwealth offered so we can afford to send our son to his dream school. The financial aid process can create uncertainty and anxiety, but the financial aid team's transparency and straightforward manner made it easy; they've been warm, helpful, and discreet. Although financial aid can be a sensitive issue, the school manages it well—not just through their financial support but by structuring school activities to avoid highlighting differences. As a result, we’ve always felt an equal member of the Commonwealth community. Our son feels proud to be supported by the school and is aware of the donors who make his education possible.
