Editorial summary

School breaks and pickup plans for SBISD families

Spring Branch ISD begins the 2026-2027 year on Thursday, August 13. The first grading period ends October 8, followed by staff development on October 9 and a student holiday October 12. Those dates create a four-day weekend, with classes back October 13. Thanksgiving week is November 23-27. The fall semester ends December 18, and students return from winter break January 5 after a January 4 staff development day.

Pickup plans depend on your child's school level. Pre-K, elementary and middle school students dismiss early September 23 for staff development. Pre-K and elementary students also leave early for parent conferences October 22–23 and February 4–5; middle school has another early dismissal February 4, while high school has separate early-dismissal dates October 7 and March 3. At each semester's end, middle and high school students have three consecutive shortened days, while Pre-K and elementary students have one. The PDF does not give dismissal times.

Spring break is March 8-12, with classes resuming March 15. March 26 is another student holiday. April 26 and May 27 may become school days if weather make-up instruction is needed. May 26 remains the last scheduled instructional day unless the district announces a change.

Does Spring Branch ISD have school on Presidents’ Day in 2027?

No. Monday, February 15, 2027, is a student holiday while staff have professional development. The academic calendar labels the date “Staff Development – Student Holiday” rather than naming Presidents’ Day.

Is Good Friday a school holiday, and are students also off Easter Monday?

Friday, March 26, 2027, is a staff/student holiday. Monday, March 29, is not marked as a holiday on the academic calendar, so regular classes resume that Monday.

Source and scope

About the Spring Branch ISD 2026–2027 Academic Calendar calendar

Data source

Dates and school-level schedules come from Spring Branch ISD's English Academic Calendar 2026-2027. The district Events page links to the English academic PDF and a separate Testing Calendars page.

How dates are handled

Events retain the official holiday ranges and separate January 1 holiday; continuous time away from school is stored in breaks with component event references. Official means a directly printed date, label or range, including boundaries marked on the calendar grid. Derived includes normalized names, internal event classifications, attendance-status mappings, grade scopes and editorial notes. Thanksgiving Break and Spring Break are family-facing classifications of the PDF’s Holiday – Staff / Students entries, not official source labels. The Winter Break key date combines December 21–31 and January 1 and therefore has a derived range. Pre-K and elementary conference days retain their shortened student schedule, while secondary early dismissal is recorded separately. Orientation and employee workdays outside the student year are omitted, except May 27 because it may become a student make-up day. Existing event IDs are retained for subscription continuity.

Updates

The PDF prints board approval on November 18, 2024, and does not print a revision date. The current English download and its link on the district Events page were checked on October 6, 2026.
