I guess I'm trying to figure out in practical terms what the various subtests mean. How does a 19 comprehension score affect a child in school? Advanced reasoning skills such that grade level material is not stimulating? Advanced reading skills? DS's psych said "You may not say much, but you certainly have a lot of words in your head." HOw does that affect his every day life in school. I told a teacher friend a couple of conversations I've had with DS about books we were reading together. Her comment to me was "WOW if he can reason like that, no wonder he's bored. He won't get that in school for a long time." Is that what VCI is measuring?
