Preschool through Grade 12

Tuition & Fees

An investment in a culturally diverse, bilingual private education is an investment in your child’s future. As an ISB student, your child will have access to individuals, ideas and experiences that are not typical of a traditional school environment .

If you believe ISB is the right fit for your child, the annual tuition and fees are as follows:

2020-2021 Annual Tuition

Half-Day for Preschool (Toute Petite Section and Pre-K Only) - Mornings Only
TPS: Diapers to be provided by parents.
Pre-K: All supplies included.

Preschool (Toute Petite Section, Pre-K, & Mid-K) and Kindergarten
TPS: Diapers to be provided by parents.
Pre-K, Mid-K and Kindergarten: All supplies included.


Lower School (Grades 1 to 5)
All supplies included.

Textbooks/Media billed separately.


Upper School (Grades 9 and 10)
Textbooks/Media billed separately.


Upper School (Grades 11 and 12)

When a parent’s employer or company linked to a student’s family pays ISB directly for a student’s tuition, a more flexible contract with different tuition rates than those listed above will apply.
