The Mamaroneck Union Free School District 2025-2026 school year runs from September 2, 2025 to June 26, 2026. Serving approximately 5,200 students across 6 schools, it covers the Village of Mamaroneck and Larchmont—two of the most highly sought-after, affluent communities in southern Westchester County.
The district is renowned for its exceptional arts, music, and athletics programs, alongside an intense academic environment. Mamaroneck High School consistently ranks among the top public high schools in the United States. Families should note that the district often schedules a shorter spring recess compared to neighboring districts, but compensates by offering a full week off in February to alleviate mid-winter burnout.
