The International School of Boston (ISB) is an independent, non-profit, French-English bilingual and international school, and one of the oldest, most respected bilingual schools in the United States. Located in Cambridge, this world-class accredited academic institution places the development of the bilingual brain at the heart of its mission. Offering a rich experience with rigorous programs and featuring a wide range of both local and international students and faculty, ISB prepares its students for a lifetime of learning and service.

Whether students join us in Maternelle, Lower, Middle or Upper School, ISB graduates stand apart from other day schools' graduates, because their knowledge of the world is enhanced by learning across the disciplines in multiple languages and by connecting with diverse classmates from more than 40 countries.

Preschool-8 students learn in both French and English. Chinese, German, Spanish, Latin or Greek are introduced at the middle-school level. Our oldest students, grades 9-12, can choose a curriculum that is English- or French-based. These students graduate with an American high school diploma and choose between two internationally renowned diplomas, the French or the International Baccalaureate, giving them the opportunity to succeed at leading universities in the United States, France, and around the world.

One of the many beneficial programs offered to Upper School students at ISB is the "Agora Monde" platform allowing them to connect with 60,000+ students and alumni from Lycées in the AEFE (agency for French education abroad) network around the world. They also have the opportunity to study for up to a trimester at a partner school abroad. Our younger students take advantage of all that the Greater Boston area has to offer in terms of culture, arts, and history through experiential learning programs. ISB also has a very strong athletic program that includes its Blue Terriers Varsity Interscholastic soccer, basketball, volleyball and fencing teams.
