Note: Only for Additional Days School Year (ADSY) campuses: 12 elementary schools and sixth grade at 7 middle schools (ADSY calendar approved by the Board of Trustees on January 22, 2026). Lida Hooe Elementary, also on the ADSY list, has only the Saturday school days and otherwise follows the traditional calendar. ADSY adds ten instructional days before the traditional start (July 28-August 10, so the year starts in July and has about 10 more weekday school days than the traditional calendar) and five Saturday school days: Sep 12, Oct 17, Nov 14, Jan 9 and Feb 6; otherwise it follows the traditional calendar. The key on the PDF lists 'December 14', but the grid, the board-approved version and the district's online calendar show Saturday, November 14. Professional development days (Oct 12, Nov 3, Jan 5) are student holidays. Secondary schools also release early Dec 16-17 and May 24-25. March 29 and April 19 are designated inclement weather days; the calendar does not say whether school is held on them if they are not needed.
