Additional information
At the International School of Boston, we inspire students to see the world as a place of infinite opportunity—one where friendships span continents, conversations flow naturally across languages, goals and dreams expand beyond borders, and diverse experiences build empathy, understanding, and a deeper connection to humanity. This is an education for all, with far-reaching benefits that impact opportunities and perspectives for life. Here, every lesson, interaction, and experience challenges the limits of a traditional education.
