School and Office Hours
Beginning with the 2017-2018 school year, the Texas Education Agency began counting a school district's number of instructional minutes (75,600 minutes) instead of instructional days (previously 180 days). This change, along with Allen ISD's designation as a District of Innovation, allows Allen ISD to begin school a week earlier in August. In order to provide staff development days and the proper number of minutes, the elementary and middle school school days were extended by ten minutes. The Lowery Center school day is five minutes longer.
