During the 2023 Legislative Session, the Legislature considered House Bill (HB) 1479, a measure which would have prohibited isolation and further restricted restraint in public schools. While the bill did not pass, the Legislature provided the Office of Superintendent of Public Instruction (OSPI) with designated state funds to begin actualizing the goals of the Legislature to eliminate student isolation and track and reduce the use of restraint. This report summarizes activities undertaken by OSPI's Reducing Restraint and Eliminating Isolation (RREI) project team as mandated through 2023's biennial Operating Budget [ESSB 5187 501(4)(mm)] and 2024's Supplemental Operating Budget [ESSB 5950 501(4)(mm)]. OSPI's approach is anchored in bottom-up leadership and nonpartisan collaboration. Great care has been taken to imbed inclusivity, community voice, and qualitative data analysis into the design and implementation of the RREI project.
