The Dallas Independent School District releases a yearly calendar that marks the major holidays—Thanksgiving break, winter recess, spring break, and summer vacation—as well as district‑wide days off such as Martin Luther King Jr. Day, Presidents’ Day, and Texas Independence Day. In addition, the calendar notes professional‑development days when students do not attend but teachers are on campus, and any optional “teacher‑in‑training” days that may affect after‑school programs. Understanding each category helps you see where flexibility exists and where it does not.
The official schedule is posted on the Dallas ISD website each summer and is reviewed by the board before the new school year begins. Updates may be issued mid‑year for weather‑related closures or unexpected state mandates, and the district typically emails families and posts notices on its portal. Because the dates are publicly available and subject to change, checking the source regularly is a core habit for any parent or caregiver who wants to stay ahead of scheduling surprises.
