Relating to references to years in instructional material used in public schools.

SB 2249 requires Texas public schools to use "BC" and "AD" instead of "BCE" and "CE" when referencing years in instructional materials. It directly affects public school curricula and textbooks acquired on or after September 1, 2025, while allowing materials that explain "BCE" or "CE" terminology. The law does not apply to instructional materials purchased before the effective date. This is a procedural change to standardize year references in school materials, with no impact on existing textbooks or materials explaining historical dating systems.
