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. 370 students are currently enrolled in ISB’s Pre-K 3-8th Grade program.

“Restoring Faith in Humanity and Yourself in 5 Million Easy Steps” by Brenna DiCola, ISB Math Teacher

Since graduating from Swarthmore College, Brenna has worked with students in grades K-8 at private schools around Philadelphia, in Lawrence, KS, and in Madrid. She has taught everything from English and Social Studies to Science and Technology, but her passion is Math Education. This past summer, Brenna moved to New York and found a home at ISB, where she currently teaches 6th and 7th Grade Math and serves as Head of the Middle School Math Department. In 2015, Brenna took a five-month hiatus from the classroom to hike the Appalachian Trail, a 2,189.2-mile trek through fourteen states. During ISB's 2020 Pecha Kucha Evening in early March, Brenna shared about her journey and the many lessons she learned along the way in her presentation: “Restoring Faith in Humanity and Yourself in 5 Million Easy Steps."

Leadership through Science

Earlier this month in Science class, 8th Graders chose to explore and present on a topic of their choice related to chemistry. Topics included freezing ice cream, researching individual chemists who made significant contributions to the field, exploring neutralization, taking a persuasive stance on soda, and more! Throughout these projects, students were able to choose what interested them most and conduct their own research.
