BooBoo,
I do hope things go well for you..when we took dd 9 in for eval (developmental Pediatrician) I made sure to tell her that my dd's behavior is very different at home than it is at school. She took that into account when making her evaluation. Obviously there are some "triggers" at school for dd that can cause some less than desirable behavior.
You know your own child best, just don't be railroaded by someone else's opinion and ask tons of questions...I did.
Good luck and please keep us posted!
