HB 474 amends Subchapter Z, Chapter 25, of the Education Code to require school districts to adopt policies regulating attire and regalia for graduation ceremonies and other official school events. The policies must include an approval process with specific criteria and cannot prohibit culturally significant or academic attire unless it poses a safety risk or impairs vision or mobility. The bill defines culturally significant or academic regalia as items such as cords, stoles, or symbols representing a student’s cultural heritage, honor society membership, or student organization affiliation. The act applies to the 2025-2026 school year and takes effect on September 1, 2025, unless enacted immediately by a two-thirds majority vote.
