Adirondack Central School District’s school sequence reflects a recent consolidation: Boonville Elementary serves prekindergarten through fourth grade, followed by grades five through eight at Adirondack Middle School and then Adirondack High School. West Leyden Elementary closed in June 2025, so families encountering older school listings should understand that its students moved into the Boonville-based organization.
Classroom work has also connected students with the surrounding community. In a 2024 village flower-bench project, agriculture students grew flowers while carpentry students designed and built benches and planters for Boonville’s Main Street. The carpentry class carried dual credit through Mohawk Valley Community College. Performing arts provide another avenue for participation, with middle-school choral concerts, student art displays, and high-school musical theater appearing in district programming. Parents use SchoolTool for the student portal and ParentSquare for school communications.
