Welcome to International School of Brooklyn.
1. Schedule a tour of the school. Parents and guardians meet ISB's administration, learn about the bilingual program, and have the opportunity to ask questions. Tours are for parents/guardians only; children do not attend.
2. Submit the online application for the 2026-2027 school year. Applications open September 2, 2025, and the deadline to submit is December 8, 2025. Supplemental materials, such as teacher reports and transcripts, are due by January 8, 2026.
3. Language considerations. For Pre-K 3 to Kindergarten, applicants from all language backgrounds are welcome; for 1st to 5th Grade, applicants should speak, read, and write in French or Spanish at grade level, with a language assessment part of the application. Middle School offers options for students starting or continuing French or Spanish, and all students must be fluent in English to enter Middle School.
4. Admissions visits. Parent interviews are typically conducted for Pre-K4 to 5th Grade; student visits occur for 1st to 8th Grade, during which language assessments and/or writing exercises may be completed; a weekend playgroup is offered for Pre-K 3 to 5.
5. Recommendations. The current teacher should submit the teacher recommendation form, ideally after November 1, for the 2026-27 cycle; the form is due by January 8, 2026.
6. Fees, entry points, and waivers. Fee waivers are available for families facing financial hardship, for those who applied last year, or for families affiliated with Early Steps and Prep for Prep programs. Entry points include Preschool (Pre-K3, Pre-K4, Kindergarten) and 6th Grade, with occasional admission to other grades; siblings are given special consideration but not guaranteed.
7. Notification and next steps. ISB follows ISAAGNY notification dates; Pre-K3 and Pre-K4 notifications occur February 26, 2026; Kindergarten on February 5, 2026; 1st–8th Grade on February 11, 2026. After notification, families proceed with enrollment, transportation, and other arrangements.
ISB offers a tuition assistance program to support enrollment across income levels. In 2023-2024 ISB granted more than $2.9 million in tuition assistance. In 2024-2025, over $3 million in tuition assistance was awarded, reaching about 30% of ISB's student body. Families applying to all grades may submit a separate application for tuition assistance through Clarity.
