We had a similar situation with DS. The woman who administered the test had never come across anyone like him. She took his results to her supervisor for translation. It did what it needed to do for now, as far as getting him services and DYS, but it wasn't complete. At some point he's going to have to re-test (if I can ever afford it!)
