Maybe they just observe how ur child interacts with you n whether or not you speak good English.... ??? Just a guess. Sometimes it may not be necessary to speak to u n the child if they can see you n your child has good spoke English.

He was totally out of control. Kicking screaming...worse I have ever seen. Lucky we have another IS offer near our home. I guess no hope for me..Happy for you guys tho.
