Relating to a policy adopted by a school district or open-enrollment charter school regarding the expression of dates.

This bill (SB 2617) requires Texas public school districts and open-enrollment charter schools to adopt policies mandating the use of "Anno Domini (AD)" and "Before Christ (BC)" when expressing dates during student instruction. It prohibits schools from purchasing or selecting curriculum materials that use alternative date formats (like "CE" or "BCE"). The policy applies to all instructional materials and takes effect for the 2025-2026 school year, unless passed with a two-thirds vote for immediate implementation. The law directly affects school districts, charter schools, and curriculum developers by standardizing date terminology in educational settings.
