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.
