Superintendents Message

Thank you for supporting the 2025–2026 Central Islip School District Budget. This budget represents an investment in our children’s education by providing a safe and enriching environment, while also maintaining the structural integrity of our school buildings, grounds, and facilities. It remains within the New York State 2% Tax Levy Cap and reflects a fiscally responsible plan that aligns with our community’s capacity to support a wide range of programs—including academics, athletics, music, instructional technology, advanced placement, and intervention services—designed to help all students achieve their personal best.
