The Arlington Central School District Calendar 2026-2027 includes key dates, holidays, marking periods, schedules of conferences, and Regents examination windows for students, parents, and staff. In March of 2026, the Board of Education approved the 2026-2027 school calendar that will give families a head start in planning the school year. The district calendar states that the school year starts in September 2026 and ends in June 2027. The calendar is also filled with make-up days for emergencies, recess, and staff development days.
There are a few changes to the 2026-2027 school calendar. Kindergarten will have half-day sessions on the first 2 days of school. The district also has four closure days set aside for emergencies. In addition, elementary schools will be given one half day per week for conferences and professional activities. Weather-related school closure of more than the designated emergency days may be met with remote learning to ensure instructional time is met.
