About

At ISB, every gift powers possibility. Annual Fund donations are used in the year they are received, meaning your support of the Annual Fund this year will directly enhance the student experience, supporting opportunities for excellence, character, and community. Your gift helps fund every aspect of ISB’s programs, from our Global Learning initiatives and world-class academics to faculty professional development and facility enhancements.

This December, we’re calling on 125 donors to join us. If we reach our goal by December 18th, two generous ISB families will contribute an additional $30,000, amplifying the impact of every gift.

As an independent, non-profit school, ISB relies on tax-deductible gifts to the Annual Fund to achieve these critical goals. Together, we can ensure every student has the experiences, support, and opportunities to grow, explore, and thrive.

Together, we can power possibility.

With Gratitude for the ISB Community - Merci!

We are grateful for the more than 140 donors who have participated in this year’s December Challenge, Powering Possibility, so far. Together, we unlocked our $30,000 challenge gift from two generous ISB families and set a new record for community participation in this annual campaign, which provides us a strong foundation toward our larger 2025-2026 Annual Fund goals. 

Donations arrived from near and far and from current parents, faculty and staff, alumni and former students, grandparents, former parents, and friends of the school. We are grateful to every donor for helping to reach new heights and power possibility at ISB.

If you haven't yet made your donation, our December Challenge page will remain open through 12/31. Annual Fund gifts can also be made year-round on our website or by contacting advancement@isbos.org. 

Thank you again to the ISB community for helping us to achieve exceptional results!
