My first two quick thoughts would be that four is very young for testing and scores can be less reliable overall at that age and also that, also at his age, his degree of comfort with the tester and willingness to be expansive on the verbal section may have depressed those scores. When I am at a computer and can look a little more at the format of the KBIT, I might have some other ideas or completely change my mind on my prior thoughts!
Do you see any concerns with verbal development vs abstract reasoning IRL?
