Standard HISD Hours

Elementary Schools: 7:30 AM – 3:00 PM
K-8 and Middle Schools: 8:30 AM – 4:00 PM
High Schools: 8:30 AM – 4:00 PM

Summer School and the "5th Quarter"

The 5th Quarter is HISD’s expanded summer learning program designed to provide enrichment and academic recovery. For the 2025-2026 cycle, the schedule is as follows:

Start Date: Wednesday, June 10, 2026
End Date: Friday, July 17, 2026

This program is optional for many but may be mandatory for students needing additional credits or support to progress to the next grade level.

Staff Development and Teacher Induction

Before students arrive, HISD staff undergo extensive training. The 2025-2026 timeline for educators includes:

School Leaders Induction: Begins July 21, 2025
All Staff Induction and Preparation: August 1 – August 11, 2025
Mid-Year Professional Development: Dates include Sept 2, Oct 2, Nov 7, Jan 5, and Feb 13. On these days, students typically have the day off while teachers participate in training.

Why the HISD Calendar Matters for Families

The 2025-2026 calendar reflects the district's commitment to maximizing instructional time. By including 181 days, HISD aims to provide a robust educational foundation. However, this also means families must be diligent about attendance. Texas state law requires students to attend at least 90% of their classes to receive credit and be promoted.

With breaks such as the full week for Thanksgiving and the mid-March Spring Break, families are encouraged to plan travel during these designated recesses to avoid unexcused absences.
