What parents should watch for
Katy ISD often places district-wide professional days before or after major breaks — these look like “extra” no-school days but are critical for teacher planning. Also, check specific campus calendars for staggered bell times and early dismissals for elementary conferences.
Practical planning tips
- Sync early: Add Katy ISD dates to a shared family calendar and set alerts 30/14/3 days before big breaks.
- Book travel early: Winter and spring breaks are popular; flights and camps fill fast.
- Confirm with coaches: Athletic and extracurricular schedules sometimes continue through short breaks.
