The Arlington Central School District 2025-2026 school year runs from September 4, 2025 to June 25, 2026. Arlington is the largest school district in Dutchess County, serving approximately 10,000 students across 12 schools in the Town of Poughkeepsie and Town of LaGrange.
Arlington is frequently confused with the neighboring Poughkeepsie City School District, which covers only the city itself. Arlington covers the surrounding suburban areas — a critical distinction for families. The district features 4 emergency days built into its calendar and offers an 8-day spring recess. Arlington High School and John Jay High School (also called Arlington High School) are the district's two comprehensive high schools.
The first day is Thursday, September 4, 2025. Arlington starts 2 days later than most Westchester and Long Island districts.
Winter Recess runs from December 24, 2025 – January 2, 2026.
Spring Recess runs from March 30 – April 6, 2026 — an 8-day break.
The last day is Thursday, June 25, 2026 (half day for elementary and middle school). June 26 is a rating/staff day.
No. Arlington CSD and Poughkeepsie CSD are completely separate districts. Arlington covers the suburban Town of Poughkeepsie and Town of LaGrange, while Poughkeepsie CSD covers the city only. This is the #1 source of confusion for families in the area.
