Thank you for considering ISAAC's unique educational environment for your child. ISAAC is a School of Choice that accepts students from throughout Connecticut.

The lottery registration and admissions process at ISAAC requires attendance to one of the June Registration dates. Each year ISAAC admits new incoming students for each grade, depending upon the availability of open slots. Students are selected based on a fair, random lottery, which ensures all students have an equal opportunity to enroll. Students that are not selected will be added to the waiting list.

Upon graduation, ISAAC students attend public and Choice schools in the region as well as private and boarding schools throughout New England.
