I seriously doubt you work for DSS, or maybe you do because you seem to have an issue about parents know of rooms like this in our schools. Sounds to me like you think it should be covered up and parents have no right to know what might happen to their children during the school day, or maybe you think it's ok for a child to be locked in a room either alone or with an adult. Who knows what might happen then. Why don't you just go away.
