Katy ISD Starts Fall Semester

Katy ISD's approved 2026-2027 instructional calendar lists Wednesday, August 12, as the first day of school and fall semester. Families should confirm their child's campus information, transportation arrangements, and bell schedule before the first morning because campus schedules can differ. The districtwide calendar lists the date as an all-day instructional event and does not provide one districtwide start time. The date applies to Katy ISD campuses serving the Katy community.
