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 education I got at Commonwealth was spectacular. I had such good teachers and such good peers. And a funny thing, it kind of spoiled college for me. I went through Harvard in three years and I didn't really have the kind of college experiences that a lot of people have… Commonwealth put me so far ahead in college that it was a different experience.” —Will Brownsberger ’74, Massachusetts State Senator
