Relating to the purchase, adoption, and use of instructional materials by public schools.

HB 100 prohibits Texas public school districts and open-enrollment charter schools from using state funds to purchase or adopt instructional materials that contain obscene or harmful content or appear on the State Board of Education's rejected materials list. The bill requires the State Board to issue a 45-day notice before adding materials to the rejected list, allowing time for revisions. It also bans the use of any instructional materials - whether traditional or open education resources - listed as rejected, while permitting local funds for non-rejected materials. This law applies starting the 2025-2026 school year and became effective immediately after the governor signed it on June 20, 2025.
