What to know

The Early College calendar has a longer winter no-class period than the regular Secondary calendar.
TCC semester milestones are student-relevant dates unique to this calendar.
The second conditional bad-weather make-up date is April 30, not April 23 as on the Elementary and Secondary calendars.

Editorial summary

Planning around the Arlington ISD Early College calendar

Early College families need both the AISD and TCC dates. The first AISD school day is Wednesday, August 12, 2026; fall TCC classes begin Monday, August 17, and the TCC semester ends December 9. The Early College PDF has its own holiday schedule, so the regular Secondary calendar is not a substitute.

Winter holidays run December 21-January 8, followed by student holidays January 11-12. Students return to AISD classes Wednesday, January 13, before TCC classes begin Tuesday, January 19. The January 18 student and staff holiday falls between those return dates. December 17-18 are early-dismissal days, with the Early College school day ending at noon.

Spring break is March 15-19. March 26 and April 30 are holidays unless needed as bad-weather make-up days. The spring TCC semester ends May 12. May 25 is an early-dismissal day, and May 26 is both the final AISD student day and an early-dismissal day. Early College dismissal is at noon on those dates.

About the Arlington ISD 2026–2027 Early College High School calendar

Data source

Dates come from Arlington ISD's official 2026-2027 Early College High School Student Academic Calendar and the district calendar page.

How dates are handled

TCC milestones were included because they directly affect students. Faculty-only dates were excluded, and the Early College schedule was not backfilled with dates from the regular Secondary calendar. TCC milestones identify college-course dates only; their school status is not applicable to AISD campus operations.

Updates

Arlington ISD may activate a make-up day or update TCC-related dates. This page was verified October 3, 2026.

Disclaimer

Confirm college-course dates, campus events and weather-related changes with the Early College campus and TCC.
