Preschool through Grade 12


Are you ready to open up a world of possibilities?

At the International School of Boston (ISB), students, beginning in Preschool through Grade 12, are challenged to see things differently, think broadly and openly, and become successful global citizens. They are introduced to the world through a rigorous multilingual program within the context of a truly international classroom -- teachers and students from all around the globe.

As one of the oldest bilingual French-­American schools in the United States, ISB prepares students for one of two esteemed international diplomas, the French or the International Baccalaureate, allowing students to apply to any college or university in the world.


Who should apply?

ISB is for students who want to be intellectually challenged, aspire to be bilingual (or even multilingual), and are eager to learn with peers from over 40 different countries from around the globe. Fluency in French is not required to join the ISB community.

Admission Overview

  • Applications are given priority if received before February 15th, with decisions emailed to families on March 10th. Families have until April 10th to confirm enrollment. After April 10th, admitted applicants will have one week to respond to our offer of admission. Students placed on a waiting list are accepted when openings become available.

    • The student’s overall academic and developmental readiness for his/her grade.
    • His/her ability to benefit from an academically challenging bilingual curriculum.
    • The family’s commitment to our mission, program and diverse multicultural setting.
