ISB is an IB World School authorized for the Primary Years Programme (PYP) and Middle Years Programme (MYP). The academic program integrates the IB framework with New York State standards, offering language immersion in French and Spanish. The curriculum is accredited by the French Ministry of Education for Pre-K 3 through 5th Grade and by the Spanish Ministry of Education for the full program.

Graduates are prepared for a wide range of high schools, including independent, public, specialized, and boarding schools. Alumni have gone on to attend diverse colleges and universities in the United States and abroad, reflecting their individual passions and academic foundations in science, math, arts, and letters. Students are developed into confident, multilingual lifelong learners who act as adventurers, advocates, changemakers, and leaders.

The school provides student support services as part of its commitment to an inclusive learning environment. It maintains a 5:1 student-faculty ratio and an average class size of 18 students to ensure personalized attention.

The school admits students of all backgrounds and does not discriminate in its policies. The admissions process includes parent interviews for Pre-K 4 through 5th Grade, student visits for 1st through 8th Grade, and weekend playgroups for Preschool and Kindergarten applicants. While Pre-K 3 through Kindergarten are open to all language backgrounds, applicants for 1st through 5th Grade must demonstrate grade-level proficiency in French or Spanish.
