About the Alief ISD 2026–2027 Academic Calendar calendar
Data source
Page 1 of Alief ISD's currently linked two-page Academic Calendar supplies the dates and marking-period figures for 2026-2027. The official Calendars page links this document as Printable Calendars and offers a separate district web calendar.
How dates are handled
Official break dates and the three following Student Holiday/Long Range Planning dates are separate events. The breaks section combines only dates with no intervening student attendance and explains the added planning day. Staff development and teacher workdays outside the first-to-last student range are omitted. Names for the otherwise unnamed student/staff holidays are not invented.
Updates
Alief ISD's live Printable Calendars file was reviewed October 3, 2026. It contains both academic years. Neither page has a draft stamp, approval date or revision date; the filename alone is not used to assign those dates. This page uses the district-posted schedule without claiming a board-approval date.
Disclaimer
The PDF does not supply early-release times, report-card delivery dates, test dates or weather make-up rules. Campus instructions and later district announcements may add information or change this schedule. Keep the two academic-year pages separate when planning: they share a download, not a set of attendance dates.
