Tuition and Financial Aid

We hope that cost will not be a factor as you consider Commonwealth. Since the founding of the school, through a strong commitment to financial aid, we have been dedicated to increasing access to a Commonwealth education and welcoming as many qualified students as possible.

Financial Aid for 2020-2021

  • Tuition and fees are $49,493.
  • The average financial aid grant is $31,072.
  • Commonwealth granted over $1.4 million in financial aid.
  • Families with financial aid grants paid between $500 and $42,300 towards the cost of tuition and fees.
  • 35% of our students have financial aid grants.
  • Commonwealth extended over $10,000 in additional technology grants. The program includes families whose financial aid grants amount to more than 50% of tuition and fees. Through these dedicated grants, they can elect to purchase a MacBook Pro laptop, printer, and software at a reduced cost. On average, participants paid $370 for this package.
  • Commonwealth offers discounted standardized testing, tutoring support, and public transportation, and extends additional grants for summer programs and school-sponsored international trips.

Like many independent schools, Commonwealth employs School and Student Services for Financial Aid (SSS) to assess whether a family is eligible for financial aid and at what level. The SSS formula takes into account a family’s income, assets, and debts. To apply for financial aid, families should complete and submit a Parents’ Financial Statement (PFS) online at solutionsbysss.com and upload the requested documents by the appropriate deadlines. Please note that Commonwealth’s SSS school code is 2542.

“The financial aid program exemplifies our student’s engagement with Commonwealth’s spirit of community, diversity, and generosity. The support we receive makes it possible for her to immerse herself in a breadth of opportunities and camaraderie that inform and grow those very values, which she’s sure to take with her beyond her years here." — Parent '23
