Keller ISD will observe summer hours from June 1 through July 24 with administrative offices and facilities open Tuesday-Thursday with public business hours 8 a.m.-4 p.m. and the District closed Fridays. Employees will work remotely on Mondays to close buildings on those days as an additional cost-saving measure for the district. On those days, campus employees can be reached by email but may not be able to return all phone calls received until they return to campus. 

Keller ISD will be closed on June 18 in observance of the June 19 Juneteenth holiday, and June 29-July 3 for the week leading up to Independence Day. 

The District will resume its five-day work week on Monday, July 27, 2026.
