Editorial summary

What Ector County ISD families should know for 2026-2027

Ector County ISD uses a staggered opening. Students in PK-6 and grade 9 begin Tuesday, August 11, 2026. Students in grades 7-8 and 10-12 begin Wednesday, August 12. The last student day for all grades is Thursday, May 27, 2027, and the PDF lists 175 instructional days.

ECISD pairs several holidays with professional-development days to create longer breaks for families. Students are off September 7-8 for Labor Day and professional development, and October 12-13 for the Columbus Day holiday and professional development. Thanksgiving holidays run November 23-27; a November 30 professional-development day keeps students out through Monday.

Students are also out from the December 18 teacher workday through January 5 and return January 6. A March 5 teacher workday leads into Spring Break on March 8-12. The calendar designates February 15 and May 24 as inclement-weather make-up dates, so families should check ECISD announcements before making plans around those days.
