Elizabeth, I'm impressed with your decoding skills, thank you!
aeh, thank you for your reply, which makes a lot of sense. It looks like this DAS test did include an Adaptive subset, in which he scored low - 18th percentile. For all the other subsets and clusters of the test, his results are closer to the overall score.
I met with the evaluator today and was able to get more information. You guessed correctly: they told me he was at times inattentive and disinterested during the DAS. The professional opinion is that these tests become more accurate around 6-7 years of age.
Based on the KTEA alone he would qualify for DYS. His math, reading and writing abilities are at 3rd-4th grade level. Part of me wants to forget all this and give him more time to be a kid preschool; but then I see so much yearning to learn in him - whenever he has a spare minute, he grabs a book. And he's pretty much done with preK-2 books; now he gravitates to encyclopedias, biology, astronomy and foreign language learning books.
