Financial Aid

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 offers financial assistance to families according to their need. 

Students holding French citizenship (residing with their parents and registered at the Consulate General of France in Boston) may apply for the Bourses Scolaires Françaises, allocated by the French government. The ISB Financial Aid Program may sometimes supplement the amount granted by the French government. French citizens applying for ISB Financial Aid must also apply for the Bourses Scolaires Françaises. In some circumstances, ISB may not know how much funding the French government will provide French families before the enrollment deadline.

Families with three or more children enrolled at ISB may qualify for a discount if they apply for ISB Financial Aid.
