Preschool through Grade 12

Financial Aid

The cost of an independent school education can seem overwhelming, which is why our Admissions Office is here to help you structure a plan that works for your family.

Financial aid is available for qualifying families through the ISB Financial Aid Program. This program is entirely funded by ISB, and it offers limited financial assistance to families according to their need. 

Please note that students holding French citizenship, residing with their parents, and registered at the Consulate General of France in Boston are asked to simultaneously apply for the "Bourses Scolaires Françaises" and the ISB Financial Aid Program. The ISB Financial Aid Program may supplement the amount granted by the French government. The ISB Financial Aid application will only be reviewed once you receive the decision from the French government.

Applying for ISB Financial Aid through TADS

ISB partners with Tuition Aid Data Services (TADS) to conduct financial need assessments for families that may need assistance in paying tuition. The application process is fair and confidential. Families should apply online. TADS charges a processing fee of $39.

TADS performs a calculation and produces a report which estimates how much the family can afford to spend on education for the year. The difference between what the report says a family can afford and the cost of attending the school is called “Need”.

Application Deadline for the 2020-21 School Year:

Saturday, February 15, 2020. The application process will start in January 2020.
