Thanks so much for your replies!

My DS was just over 6 1/2 yrs when testing was done (6 yrs 10 mos now). No speech/language testing done, but we will be getting a speech assessment to include pragmatics. However, interestingly his early language development was very good (first words around 9 mos, short phrases just past 1 yr, hundreds and humdreds of words and phrases by 18 months, long and relatively complex sentences between 2-3 yrs), so he actually seemed like language was a strength early on. He is now less conversational, and will often say "I don't know" when asked a question, or "I don't get it" when we explain something to him, so certainly his language skills no longer seem to be as well developed for age as they once did.

WISC subtest scores are below (and yes, Comprehension was very low, which she used as part of the rationale for why an ASD was likely and needed further assessment... but almost all verbal scores are low compared to PRI).

VCI
similarities 13
vocabulary 9
comprehension 7
information 11
word reasoning 9

PRI
block design 12
matrix reasoning 16
picture concepts 16

WMI
digit span 15
letter-number sequencing 11

PSI
coding 11
symbol search 13

Thanks again!
