HB 458 amends Section 37.0013(a) of the Education Code to expand disciplinary alternatives for students in pre-kindergarten through grade five and for students receiving special education services. The bill mandates that school districts and open-enrollment charter schools establish programs emphasizing positive behavior intervention strategies, trauma-informed practices, social-emotional learning, and restorative practices. It restricts the use of in-school suspension, out-of-school suspension, or placement in disciplinary alternative education programs for these students, except in cases involving weapons, violent conduct, or substance-related offenses. Additionally, the bill amends Section 37.005(c) of the Education Code to prohibit out-of-school suspension for students in pre-kindergarten through grade five except for serious offenses, including those related to weapons, violent crimes, and substance abuse. These provisions take effect in the 2025-2026 school year, with the act becoming effective immediately if passed by a two-thirds vote or on September 1, 2025, otherwise.
