HB 466 revises the Education Code to enhance policies and procedures for public school students with disabilities, emphasizing independence, self-determination, and compliance with federal regulations. The bill expands definitions and clarifies the roles and responsibilities of parents, educators, and representatives in special education services. It requires additional supports, such as transition planning and the inclusion of supported decision-making agreements, to help students with disabilities develop independence. The bill also establishes a framework for appointing educational representatives for adult students with disabilities who are certified as unable to provide informed consent but are not legally deemed incompetent. These representatives must prioritize the student’s preferences, goals, and best interests, while students retain the right to revoke the appointment if capable. Schools must ensure confidentiality and procedural safeguards to protect students' rights. The act takes effect on September 1, 2025, unless enacted sooner through an emergency clause.
