ISB opens a world of possibilities for students from Preschool through Grade 12 by providing the rigorous bilingual education, inclusive cultural experiences and flexible global mindset needed to learn and lead in the world of tomorrow.
You don't have to travel far to give your child a global education. ISB immerses students in the unlimited possibilities of a global, multilingual education, empowering them to learn anything, connect with anyone, and be exceptional anywhere.
Here, we redefine what it means to educate for the future. Our core identity as a Center for Global Learning represents our bold and visionary commitment to preparing students for the complexities of an interconnected world. More than just a school, we are a hub for global engagement, where learning is intentionally designed to develop the knowledge, dispositions, and skills students need to thrive in a multicultural and constantly evolving global landscape.
Our historic campus is located in Cambridge, Massachusetts, at the intersection of Arlington, Somerville, and Cambridge. ISB educates students in Preschool through Grade 12, beginning with a unique approach to bilingual learning in Preschool through Grade 8. In the Upper School, students choose from one of two internationally-renowned academic tracks: the International Baccalaureate (taught in English) or the French Baccalaureate.

Our children have attended 4 schools in 4 different countries and ISB has been the best at welcoming them, and making sure they were happy and well integrated to be in a good position to learn and reach their dreams.
Teachers are the best at pushing the students beyond their limits. Students not only learn but take initiatives and demonstrate that they are already our future leaders.
Very pleased that both my children received their education at ISB.

When you graduate from the IB, the study skills you gain and the maturity you develop in terms of taking accountability for yourself and your academics are invaluable. I built a foundation of what it means to study, what it’s like to have a plan, and what it's like to think forward.

The general culture that ISB gives you, to know a little bit about everything, is unmatched. I will have regular conversations with high-level business school students, and they will discuss the things they have just learned. I’ll be struck by the fact that it’s something I learned in tenth grade at ISB. It’s such a broad, deep education that really covers everything. It’s just a different level.
- Luca Didomenico '15- September 29, 2025
Academically, ISB prepared me exceptionally well. When I arrived in college, I had already encountered a significant amount of the content, which had been explained clearly by my teachers. The preparation for the Bac was preparation for college in general. It’s just what you do at ISB every week.
