Commack Schools Begin September 2

The Commack Union Free School District will begin the 2026-27 school year on Wednesday, September 2. The district's official calendar identifies the date as the first day of school for students across the district. Families should use the district's back-to-school materials and school-specific information for details about transportation, schedules, meals, and other opening-day procedures. The district serves Commack students from primary school through high school, making the date a broad local schedule change for students, caregivers, and school-bound drivers.
