Financial Aid

We understand that a bilingual education is not only an investment of time, but also finances, and we encourage families to explore if they are eligible to receive financial aid. GISB awards aid on the basis of financial need. Awards are based on recommendations from School and Student Services for Financial Aid (SSS), and the school’s available budget, which may vary from year to year. Financial aid is typically granted for school tuition as well as after-school program costs and overnight field trips. For more information, please click here.

Please note that families applying to the International Student Program are unfortunately not eligible for financial aid.

Financial Aid is currently limited to a maximum of 50% of the cost of tuition for students in preschool through grade 5. Families with children enrolled in grade 6 or higher are eligible for financial awards up to 100% of demonstrated need.

Please visit School and Student Services’ secure family portal to complete an application using GISB’s School Code: 3139. The cost to complete an aid application is $60; you will be prompted for payment information at the end of the application process. To learn more about how to submit a financial aid application, please read the Guide for Financial Aid Applications and the Parents’ Financial Statement  Workbook.

All recipients of financial aid must complete the process annually in order to be considered for financial support.
