Bans using seclusion to confine a student

HB 455 bans locking students alone in a room (seclusion) in Missouri schools, effective July 1, 2022. It prohibits confinement methods that obstruct breathing, cause asphyxia, apply pressure to the chest/abdomen, or block circulation. The law applies to all public schools, charter schools, and publicly contracted private providers. It does not affect standard timeouts, in-school suspension, or detention, which are explicitly excluded. The bill focuses on preventing physical harm during disciplinary practices by banning specific dangerous restraint techniques.
