    From International School of Boston

    Long known for its excellence in bilingual French and English education, the International School of Boston (ISB) launched in September 2021 the "Éveil aux langues" program in Spanish and Chinese from PreK-Grade 1, and the Spanish-language program from Grades 2-5.

    After the successful launch of these 2 programs, ISB will now be offering its Grades 2-5 students the choice of learning either Spanish or Chinese. Elementary students have the opportunity to become trilingual, and secondary students have the option to study Spanish at the novice or fluent level within the English-based International Baccalaureate curriculum.

    ISB 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 thrive at leading universities in the United States, France, and around the world.
