HB 430 amends Section 29.003 of the Education Code to revise the terminology used to describe certain disabilities in determining eligibility for special education services in public schools. Specifically, the bill replaces the term "emotional disturbance" with "emotional dysregulation" while maintaining the same definition as outlined in federal regulations (34 C.F.R. Section 300.8(c)(4)). This change does not alter the criteria for eligibility but updates the language to reflect a less stigmatizing and more current understanding of the condition. The legislation is scheduled to take effect on September 1, 2025.
