Note: Approved by the Aldine ISD Board of Trustees on Jan. 13, 2026; the posted PDF was last updated July 22, 2026.

The district calls the Oct. 12-16 and Feb. 8-12 weeks its October and February student holidays (midterm breaks). Oct. 12, Jan. 4-5 and Feb. 8 are staff development days with no school for students; classes resume Jan. 6 after the Midwinter Break. Dec. 18 is a half day for students. The calendar notes that some schools may have calendar adjustments for specific class schedules.

We fetch this document again every day and compare it with the version we verified; if the district changes it, the dates here are read again.

Note: Only for the Additional Days School Year (ADSY) campuses Ermel, Harris and Vines (the January 2026 approval announcement also listed Smith Elementary; the current calendar names only these three). The Board approved the 2026-2027 calendars, including the ADSY dates, on Jan. 13, 2026; the posted PDF was updated June 3, 2026. ADSY starts July 27 and ends June 17, so the year starts in July and has about 23 more weekday school days than the traditional calendar (198 vs 175 computed); Election Day (Nov. 3) and Dec. 18 are regular school days here. Aug. 10, Oct. 12, Jan. 4 and Feb. 8 are marked as student holiday/work days. Students return Tuesday, Jan. 5 after the Midwinter Break (Dec. 21-Jan. 1) and the Jan. 4 staff development day: the grid, the staff development list and the third grading period (Jan. 5-Mar. 12) show Jan. 5 as a school day, and Ermel Elementary's online calendar marks Jan. 4 as the only no-school day and Jan. 5 as the start of the third nine weeks; the calendar's 'Important Dates' box (like the January approval announcement) still says classes resume Jan. 6. The Student Holidays list names Oct. 5 as a staff development day, but the grid shows Oct. 5 as a school day (Oct. 12 is the work day), and the Ermel and Vines campus calendars list no-school days on Aug. 10 and Oct. 12-16 but none on Oct. 5. Red-marked ENVI2ION days (mostly Wednesdays, August-March) are school days. No inclement weather days are marked. The Spanish page lists a staff development day on May 26 instead of the Mar. 26 student holiday; both grids and the Ermel campus calendar show Mar. 26.
