Offering a rich experience with rigorous programs, ISB prepares its students for a lifetime of learning and service.



The ISB Way

The ISB Way is our distinctive approach to engaging with our students, from Preschool (Maternelle) through Upper School.

In the ISB Way…

  • Each student is continually challenged but unconditionally loved.
  • Mastering a language other than one’s own is a way to find success and fulfillment in a global world.
  • Differences in a student’s ethnicity or socioeconomic background are reasons for celebration, not alienation.
  • Daily achievement is measured not only by test scores, but also by a student’s capacity to relate to other citizens of the world.
