School year by the numbers

Student attendance days: 181 days; Calculated from official datesCalculated from 206 weekdays between the first and last student days, adjusting for 26 confirmed no-school weekdays, 1 conditional make-up weekday currently listed without regular classes, 2 listed weekend attendance days. The scheduled attendance dates may change if the district activates a make-up day.
Total no-school weekdays: 26 weekdays; Calculated from official datesCounted from published no-class events between the first and last student days. Weekends and shortened school days are excluded, and overlapping events count once.
Longest listed break: 17 consecutive days; Calculated from official datesDec 18, 2026–Jan 3, 2027, including weekends. The stretch contains 11 confirmed no-school weekdays.
Long weekends: 5; Calculated from official datesCounts three- or four-day no-school stretches formed by a weekend plus one or two confirmed weekday closures. Longer school breaks are excluded.
Full-week breaks: 3 breaks; Calculated from official datesCounts continuous no-school stretches containing at least five confirmed weekdays without regular classes. Adjacent holidays and weekends remain part of the same break.

What to know

September 18, October 9, November 6, January 5, and February 5 are full attendance days here but student holidays on the regular calendar.
October 23, February 12, and March 29 are half-days here but no-school dates on the regular calendar.
ACE students attend a half-day January 4 and a full day January 5, so the winter no-school period does not extend through those dates.
The April 3 ADSY half-day falls on a Saturday.

Editorial summary

How the ACE Resource ADSY calendar differs

The ACE Resource ADSY calendar keeps the same August 12 first day, May 26 last day, and grading-period boundaries as the regular San Antonio ISD calendar. Its attendance pattern is different. September 18, October 9, November 6, January 5, and February 5 are marked as student full days instead of student holidays.

The official winter break runs through Jan. 1. Students next attend Monday, Jan. 4 for an ADSY half-day, followed by a full student day Jan. 5. Other half-days are Oct. 23, Jan. 23, Feb. 12, Mar. 29 and Apr. 3; Jan. 23 and Apr. 3 are Saturdays. The calendar does not list half-day dismissal times.

Feb. 15 is a holiday also reserved for bad-weather make-up instruction. Students may attend if the date is activated. Unlike students on the regular district calendar, ACE students attend an ADSY half-day on Mar. 29. The date also carries the bad-weather make-up designation.

Source and scope

About the San Antonio ISD 2026–2027 ACE Resource ADSY calendar

Data source

This calendar uses San Antonio ISD’s official ACE Resource ADSY calendar for Hot Wells Middle School, Poe Middle School, and Crockett Academy. The PDF was approved by the Board on May 11, 2026. The district Board Meeting Schedule supplies the named October or February holidays where the instructional PDF uses a generic holiday label.

How dates are handled

Full-day and half-day attendance dates follow the ACE calendar, including two Saturdays. Breaks reference their component events and stop before the next ACE attendance date. February 15 is a conditional bad-weather make-up day; March 29 is an ADSY half-day also bearing the make-up symbol. The ACE announcement explains the program name and its 11 additional instructional days. The noSchoolDayEventIds index contains confirmed no-class or no-student events and excludes conditional make-up dates. Conditional attendance is a normalized interpretation of official make-up designations; the event basis and source labels retain the official evidence.

Updates

The ACE calendar is campus-specific. A revised PDF or direct message from one of the three campuses should take priority, especially for half-day dismissal, transportation, meals, or Saturday attendance details.
