Overview
Northside ISD’s calendar balances a mid-August start with a late May finish and includes built-in teacher workdays and assessment windows. For San Antonio families, local events (fiestas, local holidays) can also interact with district schedules — so keep an eye on community calendars.

Parent planning notes
Northside occasionally schedules professional development on Fridays to create long weekends for staff; this can mean extra no-school days for students. If you have students across multiple districts, cross-check calendars to avoid double conflicts.
Family hacks
- Coordinate a neighborhood childcare roster for professional days.
- Use the district PDF link to subscribe to campus alerts.
- Ask teachers about major project due dates around quarter ends.
Wrap-up
Northside’s calendar is mostly predictable; use it to plan vacations, camps, and doctor appointments around peak school demands.
