Tuition and Financial Aid

Tuition at Commonwealth for 2019-20 is $45,848, with additional fees of $1,971.

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 welcoming as many qualified students as possible.

  • 30% of our students receive financial aid.
  • In 2019-20, the school granted more than $1.3 million in aid.
  • The average financial aid grant in 2019-20 is $29,973.
  • To ensure that every student has access to a computer, our Technology Grants Program helps families that receive more than 50% financial aid to purchase a new system at a reduced cost. For 2019-20, Commonwealth granted $9,820. On average, families paid $326 for a MacBook Pro laptop, printer, and software through this program.
  • As much as possible, Commonwealth supports families in meeting the costs of students’ foreign exchange trips and tutoring arranged through the school.

Like many independent schools, Commonwealth employs School and Student Services for Financial Aid (SSS) to determine each family’s level of need. The SSS formula takes into account a family’s income, assets, and debt. To apply for financial aid, families should complete and submit a Parents’ Financial Statement online at and upload the requested documents by the appropriate deadlines.
