ISB Summer School 2025
Purpose of the ISB Summer School Program:
To provide students with opportunities during the summer for academic review and/or enrichment, and for enrichment opportunities through a variety of different “exploratory camps”.
Please Note:
1. We have an Early Bird reduced tuition fee that will be applied to all registrations received by 3:00 pm on Friday, April 11th.
2. Please scroll down below for information about all our Summer School programs, courses, and dates.
3. Should the need arise to close campus for the remainder of summer school for some unforeseen reason, we will switch to virtual school and online learning via Zoom in classes where possible. In this case, we will provide refunds as follows:
· If we find out before summer school begins on June 16th that we need to switch to virtual school, any student who cancels will receive a full refund.
· If we need to switch to virtual summer school after summer school has started, full refunds will be provided for all days left in the session for students who cancel and do not attend virtual school.
