my daughter was tested aged 3:11 which I know is very young but we needed to do it for early school entry. She scored 99.6 percentile or IQ 140. There was a 20 point difference between verbal and performance scales. The psych said normally this could be a possible issue but given that both were in the gifted range, she was not concerned. My feeling from observing the session was that she found 1.5 hours straight very tiring and I wonder whether there could be some under estimation going on. On the other hand, her skills are definitely more advanced in the verbal area esp reading. Any suggestions, insight? Should we retest later on? Thanks
