LISD School Hours Are Changing This Year — Here's What to Confirm Before August 12

Teachers start heading back to campus soon. The first day of school is August 12. That's 19 days away. Plenty of time — if you use it.

Here's what actually matters this year: LISD swapped the start times for middle school and high school for 2026-27. Not a minor tweak. If you have a middle schooler, they now go in earlier than a high schooler in the same house — the opposite of how it worked last year.

The specific hours for each level are posted through the district — confirm them directly at your campus or on the LISD website, because the details matter and last year's times no longer apply.

For Flower Mound families juggling two kids at different schools, the gap between an elementary dismissal and a high school dismissal can run over an hour. Aftercare, carpools, work schedules — all of it hinges on knowing which bell applies to which kid.

Bus riders have an extra layer to check. Routes may affect your child's actual arrival and pickup window, and those windows shift when dismissal times shift. Last year's stop time may no longer apply.

What to do before August 12: - Call or email your campus directly to confirm start and end times — elementary early release times vary by campus. - If your kid rides a bus, verify the route and pickup window through the district. - Check the full academic calendar at lisd.net/our-district/about/calendars.

The first day is a Wednesday. Lock down the logistics now, not the morning of.
