Understanding the Katy ISD Calendar Structure
The 2025-2026 calendar is structured to maximize instructional time while also providing necessary breaks for student and staff well-being. The total number of instructional days is set to meet state requirements, ensuring that Katy ISD maintains its high academic standards.
The district is known for its transparency in the calendar-setting process, often soliciting feedback from parents and community members before the Board of Trustees makes its final decision. This collaborative approach ensures that the calendar reflects the needs of the Katy Independent School District community.
