With the regard to the verbal parts of the WPPSI-IV - doesn't a kid need both high IQ and environmental enrichment to get a high VCI score? I don't think it's possible to enrich an average kid to a super high WPPSI-IV VCI score? (is it?)

(I wondered about this b/c my kid hit the VCI ceiling when tested at 3:5 - I asked if we had overdone storytime or accidentally hothoused him? We were told no). (we just read him stuff he was interested in and answered his questions as best as we could).
