Thank you aeh, that is VERY helpful.

I talked to the speech pathologist, she only did an articulation assessment, not expressive language. We will definitely look into testing him for overall language ability. I didn't even think of that but it makes a lot of sense given his reading and writing probably has at least 2-3 grades in gap.

I do want to add that we are a bilingual family. Do you think that could have penalized the score too?

Do you have an opinion about WISC-VI vs WISC-V? I didn't know the differences going into the test. An educational psychologist told me that I should have gone with WISC-VI because she believes many examiners don't have enough experiences to interpret non-conventional answers, especially for verbal comprehension.

Really appreciate your inputs.
