Establishing a statewide network for student mental and behavioral health.

SB 5126 creates a statewide network to coordinate school-based mental and behavioral health services for Washington K-12 students. It directs the Office of the Superintendent of Public Instruction (OSPI) to lead strategic planning, streamline access to resources, and establish regional programs through Educational Service Districts. The bill requires schools to implement evidence-based screening, prevention, and intervention services - including substance use education - and coordinate with community partners. This directly affects all public schools, students, and local education agencies by standardizing support systems currently fragmented across multiple state agencies.
