The Trauma-Informed Schools Act of 2024 amends federal education law to establish requirements for schools receiving federal funding to implement trauma-informed practices. The bill defines trauma-informed practices as evidence-based professional development that helps school staff understand how trauma affects student behavior and learning, along with disciplinary approaches that avoid harsh punishments and instead use positive interventions, restorative practices, and holistic assessments of student needs. The legislation applies to all public schools and affects teachers, staff, students, and families by requiring schools to create safer learning environments, provide staff training on trauma-informed methods, and integrate social-emotional skills into academic instruction. Schools must also ensure their discipline policies do not discriminate based on race, disability, gender identity, English proficiency, or other protected characteristics. The bill does not specify new federal funding amounts or timelines but instead requires states and local school districts to describe in their federal grant applications how they will support and increase trauma-informed practices using existing education funding.
