Mission & Values

At the International School of Boston, equipping students with the ability to speak multiple languages fluently and to develop critical thinking skills within the context of international mindedness is a purposeful, daily experience.

As a world-class, accredited private school in Cambridge, Mass., serving nearly 575 students from age 2 through Grade 12, ISB places the development of the bilingual brain at the heart of our mission. ISB students graduate with an American high school diploma and choose between two internationally renowned diplomas, the French or the International Baccalaureate, allowing them to thrive at leading universities in the United States, France, and worldwide.

Our vast array of co-curricular activities in the Arts, Athletics, and our Global Learning Program underscore our holistic approach to student development and our approach to preparing our students to be part of something bigger than themselves.
