Note: The Board of Trustees approved the 2026-27 instructional calendar in December 2025 (district news, Dec 15, 2025); the posted calendar was last updated 4/17/2026. Freshmen start on August 12; all other students on August 13. PLC days (Sept 21, Oct 13, Jan 4, Mar 15) and the Staff Exchange Day (Feb 12) are student holidays. March 26 and March 29 are Possible Weather Days: no school unless needed to make up bad-weather days (the district's A/B calendar shows them as non-school days and its online calendar calls them Possible Weather Make-up Days). Dec 17-18 and May 26-27 are half student days. The district's online calendar matches these dates but does not list Feb 12; the calendar PDF (Staff Exchange Day / Student Holiday) and the district's A/B calendar (Teacher Exchange Day, marked like the PLC student holidays and not an A or B day) both show no school for students that day. Memorial Day (May 31) is after the last day. No graduation dates are on the calendar or the district's online calendar, and no day count is printed.
