This report summarizes activities undertaken by OSPI's Reducing Restraint & Eliminating Isolation (RREI) project during fiscal year 2025, as mandated through 2023's biennial operating budget and 2024's supplemental operating budget. Demonstration projects incorporate "Pilot site" districts that strategically engage in the process of building systems of support, and "Demonstration site" districts that serve as learning communities to share their stories and highlight exemplary practices within these systems. Their outcomes have revealed promising practices and effective strategies for improving school safety and reducing the use of restraint and isolation. 71% of project sites decreased incidents of restraint and isolation in school year 2024-25, as compared to the previous school year. This decrease in incidents was statistically significant.
