Mount Sinai School District

What Mount Sinai School District does

Mount Sinai School District is a New York State public K-12 school district serving the Mount Sinai community on the north shore of Long Island in Suffolk County. The district operates three schools — Mount Sinai Elementary School (K-4), Mount Sinai Middle School (5-8), and Mount Sinai High School (9-12) — under the leadership of Superintendent Dr. Christine Criscione, Deputy Superintendent Dr. Peter Branscombe, and Assistant Superintendent for Business Linda F. Jensen. Programming spans academics, fine and applied arts (including orchestras, bands, drama, and Friends of the Arts), athletics (recognized by NYSPHSSA as a 2023-2024 School of Excellence), special education, transportation, and adult/community education classes.

The district's instructional technology layer is built on a Google Workspace for Education / Google Classroom foundation, with a district-wide 1:1 Device Initiative, PowerSchool as the student information system, and ParentSquare integrated with PowerSchool for family communication and conference scheduling. Instructional leadership is organized into director-level departments covering Humanities, Math/Science/Technology, Music and Applied Arts, Special Education, Athletics/PE/Health/Nursing/Security/Buildings and Grounds, and Information Technology.

Funding flows from a combination of local property taxes, New York State education aid, and voter-approved bond proceeds. A $27,993,200 capital bond referendum passed in September 2025 (78% covered by state aid) funds infrastructure modernization. In May 2026 the district initiated an over-$10M Energy Performance Contract with Ameresco covering LED retrofits, rooftop solar PV arrays, transformer upgrades, and fuel-oil-to-natural-gas conversion across all three schools, with projected annual savings above $202,000 and $9.48M lifetime savings targeted over 30 years. The district's geographic reach is limited to the Mount Sinai community, where it holds a statutory monopoly as the public K-12 provider.
