Editorial summary

What Lamar CISD families should know for 2026-2027

Lamar CISD's 2026-2027 student year runs from Tuesday, August 11, 2026, through Wednesday, May 26, 2027.

The official winter break runs December 21-January 5, but December 18 is also a student holiday and January 6 is a Student Holiday / Staff Development day.

Dates come from Lamar CISD's official 2026-2027 Student Instructional Calendar and the district Calendars page. Elementary Group A/B assignments come from the district's 2026-2027 School Hours page.

How dates are handled

This record uses the Student Instructional Calendar; dates from Lamar CISD's separate employee calendar are not imported. Events cover student attendance from the August 11 first day through the May 26 last day, so the Memorial Day and Juneteenth holidays printed after the student year are excluded. Consecutive no-class periods were calculated from the published events and weekends, while official holiday names and date ranges remain separate in the event list. Early-dismissal dates count as instructional days.
