Relating to the scheduling of the first day of school for students by school districts.

This bill amends Texas education code to establish the earliest start date for the school year. It generally prohibits school districts from beginning instruction before the fourth Monday in August, with three specific exceptions: year-round schools, large districts (190,000+ students) meeting enrollment and funding conditions, and districts designated as "districts of innovation" starting with the 2026-2027 school year. The bill directly affects all Texas public school districts by changing scheduling requirements under Section 25.0811(a) of the Education Code. It does not alter curriculum, funding, or other educational policies, only the timing of the first day of school. The changes apply to new or renewed "districts of innovation" plans adopted on or after the bill's effective date.
