About Katy ISD Schools
Katy Independent School District is one of the largest districts in Texas. It serves the fast-growing Katy and Fulshear area west of Houston. Nearly 94,000 students started the 2026-27 school year across more than 70 campuses. Dr. Ken Gregorski leads the district as superintendent. He was named to the role in January 2019 after serving as acting superintendent. For 2026-27, Katy ISD launched Legacy Virtual High School and High School Limited Open Enrollment for eligible students from neighboring areas. The district also runs the Miller Career & Technology Center, which offers specialized career programs to students from other campuses.
What Parents in Harris and Fort Bend Counties Should Know This Year
A few things stand out in this calendar.
First, fall break is here to stay. When the board adopted the 2027-28 calendar, it also confirmed a dedicated October fall break. This year it runs Friday, October 8 through Tuesday, October 12, 2027. That’s five days off counting the weekend.
Second, spring break is longer than it looks. March 10, 2028 is a Campus Professional Learning Day with no students. Spring break follows on March 13–17. Put together, kids are off from Friday, March 10 through Sunday, March 19. That’s 10 straight days.
Third, the semesters are uneven. Fall has 81 instructional days. Spring has 91. Expect a lighter fall and a longer push to May.
Fourth, there are lots of long weekends. Watch for Monday, September 6; Friday, September 17; Friday, October 22; Monday, November 1; Monday, January 17; Friday, February 11; Monday, February 21; and the April 14–17 holiday.
Fifth, the year ends on a Wednesday. The last day of school is Wednesday, May 24, 2028, with early dismissal. Plan summer camps to start the following week.
One more note on the Katy ISD School Calendar spring break 2027 search. Spring break in calendar year 2027 falls under the 2026-27 calendar, not this one. Katy ISD lists it as March 8–12, 2027. Spring break for the 2027-28 school year is March 13–17, 2028.
How Katy ISD Compares to Neighboring Districts
Katy ISD approved its 2027-28 calendar unusually early. When we checked, Cy-Fair ISD, Fort Bend ISD, and Lamar CISD had not yet published 2027-28 calendars. So the fairest comparison is against their current 2026-27 calendars. Cy-Fair ISD runs August 12, 2026 to May 27, 2027, with spring break March 15–19, 2027. Fort Bend ISD runs August 11, 2026 to May 27, 2027. Lamar CISD runs August 11, 2026 to May 26, 2027, with spring break March 8–12, 2027. Katy’s 2027-28 year starts on a similar mid-August Wednesday but ends May 24, 2028, a little earlier than those neighbors typically finish. If you have kids in two districts, recheck in spring 2027 once neighbors post their 2027-28 dates.
