Schools cannot put children in seclusion rooms as a form of punishment anymore, and must limit the use of physical and chemical restraints. The State Board of Education approved new rules Thursday for handcuffing children, controlling them with prone restraint tactics, and giving them prescription drugs to control their behavior. These measures are now limited to situations where students are an immediate danger to themselves or others, or when calming techniques don’t work. Parents of 13-year old Jonathon King of Gainesville pushed for changes after their son hanged himself in a seclusion room in 2004. Jonathan was a student in the Alpine Program, a public school in Gainesville, Ga.
