What Parents in Denton County Should Know About This Calendar
A few things stand out when you look closely at the Lewisville ISD 2026–27 school year.
First, the school year opens relatively early. August 12 is one of the earlier start dates in the DFW area, which means summer camps and family vacations need to wrap up by the second week of August.
Second, notice that March 26 is marked as a holiday following Spring Break. This gives families a slightly longer recharge window at the end of March — effectively making late March a four-day school week instead of five.
Third, March 29 appears as a Bad Weather Day. This is a planned makeup day built into the calendar. If winter storms did not cause closures earlier in the year, this day may convert to a regular school day or holiday — watch for communication from your campus.
Thanksgiving Break runs the full week of November 23–27, which is a full five-day break. That is consistent with most North Texas districts and great for families traveling out of town.
How Lewisville ISD Compares to Neighboring Districts
If you have friends with kids in nearby districts, here is a quick picture of how LISD stacks up.
Frisco ISD and Denton ISD typically open within a few days of LISD’s August start window, though specific dates shift year to year. Coppell ISD, which borders LISD to the south, often mirrors LISD’s calendar closely given the overlapping geography of families in that area. Carrollton-Farmers Branch ISD to the southeast tends to start at a similar time but sometimes schedules spring break one week earlier or later than LISD.
For 2026–27, LISD’s Spring Break falls March 15–19. If you are coordinating a trip with family members in other districts, check their calendars — you may find the weeks do not perfectly align.
Planning a Family Trip? Best Travel Windows for LISD Families
If you are trying to plan a vacation around the school year, here are the best windows.
Best for travel: Thanksgiving Break (November 23–27) is a full five days. Winter Break beginning December 21 is your longest stretch — it runs through the New Year and students do not return until January 5. That gives most families approximately 16 calendar days including weekends.
Spring Break 2027: The Lewisville ISD Calendar spring break 2027 runs March 15–19. It is a standard five-day break. If you add the holiday on March 26 into your planning, you can potentially extend a spring trip — though March 26 follows a full week of school after break, so plan accordingly.
Avoid travel: April is a clean instructional month with no breaks or holidays shown on the district calendar. This is typically when STAAR testing occurs in Texas, so keeping students in school and on routine in April is important.

School Closings History in Lewisville ISD
Denton County sits in the North Texas weather zone where ice storms and winter weather events occasionally force school closures. Lewisville ISD has historically used between zero and three weather-related closure days in a given year, with the built-in Bad Weather Day on March 29, 2027 serving as a buffer. In years with heavy ice, the district has also announced delayed starts rather than full closures. For real-time updates on closures and delays, always check the LISD website, the district’s official social media channels, or local DFW news stations — they are the fastest sources when weather changes overnight.
