aeh, I'm so glad to see you on these boards; your posts are so helpful!
The Wiat scoring is so confusing; I had to have our psych throughly explain this to us also.
Because we wanted to to qualify for DYS, we had almost the all subsets administered with the exception of written and math fluency (DD is in kinder).
The ceiling for Early Reading is 123 at 94th percentile, if you get all items correct.
I do want to add that it was important for our DD to have been tested on the oral expression and language subsets since she scored really highly in these areas and helped her achieve >99.9 percentile in total achievement. She wouldn't have qualified for DYS without it; she was ever so close in math but just barely missed it and 99 in all others except for written.
Ultra, perhaps you can speak with the psych. to adminster the required missing tests to get those subsets? I'm not sure what the timeframe to get this done is, however.
