Ha, I had to laugh at the subject line for this question. I happen to have a kid exactly your kid's age who did manage to score 145+ on the WPPSI-IV when she took it on Tuesday. So, it is possible - living proof! But ceiling issues were definitely in effect - she scored 19s on many of the subscores, leaving me wondering how much her score actually captured her abilities. I didn't need her score urgently for anything and in retrospect kind of wish we'd waited till she was old enough to take a test with more score headroom.
