Source: United ISD 2026 - 2027 Academic Calendar (Board approved December 17, 2025; revised 6/17/26) (PDF) · district calendar page

Note: Board approved December 17, 2025; this file is the revision dated 6/17/26 (uploaded to the district's file host on June 17, 2026). The district website does not answer this network, so the calendar page was read via a Web Archive capture of May 13, 2026, which linked the original 2026-27 calendar; that file has since been removed from the host and this revised version (_v2) was downloaded directly from the district's file host. The original (Web Archive copy of May 1, 2026) has the same school days; the revision adds the bad weather make-up days and the STAAR test dates. We could not confirm that this revision is the version the district's calendar page links today (no capture of the page after May 13, 2026), so parents should check the district site. Dates are read from the color-coded grid and match the student-day count printed for every month. The calendar marks all breaks and holidays as Staff/Student Holidays; Thanksgiving, Winter and Spring Break are the district's names for those weeks. Students are off December 17 (teacher work day) through January 5 (teacher work day) and return January 6. Election Day (November 3), Martin Luther King Jr. Day (January 18) and Presidents' Day (February 15) are school days on the calendar: the cells are unshaded and counted in the printed monthly student days (some web summaries wrongly list MLK Day as a holiday). The February holidays are Friday, February 19 and Monday, February 22. Professional development/PLC days with no students: October 9, March 26 and April 30. Bad weather make-up days: October 9 and March 29; both are no-school days unless the district needs them to make up days lost to bad weather. December 16 is an early release day for high schools only; the last day, May 26, is an early release day for all schools. High school graduations are May 26-27 at the Sames Arena. 174 student days = 83 (first semester) + 91 (second semester), as stated on the calendar.
