The Smithtown Central School District is one of Suffolk County's largest and most sought-after suburban districts, educating about 8,700 students across 11 schools spanning several North Shore hamlets.
Because of its size, Smithtown's calendar is an essential operational tool. It features separate, strategically timed spring recesses and clearly designates built-in emergency closure days. In the event of severe North Shore snowstorms, the calendar outlines a clear policy for transitioning to remote instruction or utilizing make-up days in the spring.
