Our History

International School of Brooklyn (ISB) was founded in 2005 to create an intimate and multicultural setting with a balanced and challenging academic program.

The story of ISB began in 2003, when a group of committed parents met and together set in motion the process of creating an independent language immersion school. In September 2004, ISB received its operational charter from the New York State Department of Education and spent the 2004-2005 school year piloting language immersion playgroups in Park Slope, Cobble Hill, and Brooklyn Heights, laying the foundation for the preschool opening.

In September 2005, ISB launched its preschool program in Park Slope with 16 students in its inaugural class. In less than two years, ISB had expanded to 65 students in Nursery through 1st Grade, necessitating a move to a larger facility in Prospect Heights.

ISB continued to grow through 3rd Grade at this location, and in September 2010, ISB moved into its current location in Carroll Gardens. 342 students are currently enrolled in ISB’s Nursery-8th Grade program.
