Chino Valley Unified School District in 2025-2026 opens on the earlier side of the school-year cycle on Aug 4, 2025 and wraps before Memorial Day week on May 21, 2026. The longest no-school windows highlighted here are Thanksgiving Break (Nov 24-28, 2025), Winter Break (Dec 18, 2025 - Jan 2, 2026), and Spring Break (Mar 30, 2026 - Apr 3, 2026). Spring Break is placed near the end of March.
For families comparing calendars, the useful takeaways are that the early start can affect summer camp, childcare, and back-to-school travel timing, the May finish can move summer planning earlier than districts that run into June, Thanksgiving is shown as a full-week break, and winter break is one of the longest no-school stretches on the calendar. That combination can shift when to book trips, arrange care, or double-check school-specific notices.
Most of the no-school time is concentrated in the major break windows rather than scattered across the year.
The calendar dates on this page are checked against district-published materials; families should still verify late changes against the official district calendar page.
