Last night a local television station had a news story about a student north of the river who was placed in a time-out room. They interviewed the mother who indicated she learned her boy was placed in there for running in the hall; he has ADHD. She said he was in there for over two hours and that he was nine-years-old. The video showed a lighted small room with a bean-bag and carpet. The mother continued that she had not given permission to the school for her son to be in such a place.
Parents need to not be surprised (like this mom) when their child is placed in disciplinary situations that are inappropriate. To avoid it, one thing a parent can do is make sure that discipline is spelled out in the IEP; and, if there are techniques that the parent does NOT want used then the parent can write to the school and notify them that you do not give consent for them to do it.
Also, parents can request manifestation determination meetings that is suppose to define between which behaviors are disability related or not.
The IEP Center dot com has advocates who assist parents in MO and KS with these issues. We are not attorneys and do not give legal advice.
