What to know

IDEA San Antonio begins August 11, 2026 and ends May 25, 2027; other IDEA regions use different opening and closing dates.
The October professional-development day and two IDEA holidays produce a continuous student break, even though the entries have different labels.
The San Antonio quarter-ending dates are October 16, 2026, January 8, 2027, March 19, 2027, and May 25, 2027.
January 4-5 is kept separate from the official winter holiday so the source wording remains clear while the January 6 student return is still easy to plan around.

Editorial summary

Planning around the IDEA San Antonio 2026-2027 calendar

San Antonio’s revised regional calendar starts classes Tuesday, August 11, 2026, and ends Tuesday, May 25, 2027. The July 15 update is the official version used here. October 8 is a no-school professional-development day, followed by IDEA holidays October 9 and 12. Students also receive the full Thanksgiving week and the December 21-January 1 winter holiday.

Spring break is scheduled March 8-12, but the adjacent March 15 professional-development day keeps students home through Monday. IDEA holidays on March 26 and 29 form another four-day weekend, and April 23 is a separate holiday. The official calendar does not mark any early-release dates.

The San Antonio calendar marks Friday, August 7, 2026 as Student-Family Engagement Day. It is not the first regular school day, and the PDF does not publish hours or a campus agenda.

Does this calendar apply to every IDEA campus in San Antonio?

This is the official regional academic calendar for IDEA campuses in San Antonio. Campus-specific testing, events, bell schedules, transportation details, or emergency schedule changes may not appear on the regional calendar.

Does the official IDEA San Antonio calendar include Spanish?

Yes. The official regional PDF includes calendar pages in both English and Spanish.

Can the 2026-2027 dates change because of weather?

Yes. The PDF says the calendar may change in response to nearby school districts and inclement weather. Families should check IDEA alerts and campus messages before relying on a date affected by a closure.

Is this the revised San Antonio IDEA calendar?

Yes. This page uses the official San Antonio regional PDF updated July 15, 2026. Families who saved an earlier version should compare it with the current official link before making plans.

Does the San Antonio PDF list an early-release day?

Source and scope

About the IDEA Public Schools 2026–2027 San Antonio calendar

Data source

This page uses IDEA Public Schools’ official 2026-2027 San Antonio Academic Calendar PDF, updated July 15, 2026, plus the network’s Academic Calendars page. Both were checked October 5, 2026. The PDF supplies student-year boundaries, IDEA holidays, no-school training days, quarter endings, and any region-specific schedule symbol.

How dates are handled

Dates were checked against the visible month grid and printed event labels. Staff development before August 11, 2026 and the teacher workday after May 25, 2027 were excluded because they fall outside the student year. Separate no-school entries are described as one continuous break only when every intervening calendar day connects them.

Updates

IDEA notes that the San Antonio calendar can change for surrounding-district updates or inclement weather. A later official regional PDF or campus notice should take priority over this record, especially when a closure affects transportation, make-up instruction, or a planned return date.
