Hi - I am new here (from Australia - we don't see to have anything vaguely resembling the support network you have in the USA). My background is that I have three lovely boys (8,6 and 4) and the oldest two have been identified as gifted. My concern is for the elder boy (8) who has widely varying scores. The pyschologist gave him the WISC-IV test but didn't give us individual scores just the overall scores. These were:

VCI: 144
PRI: 112
WMI: 129
PSI: 94

Yes, wide variation ! We have since taken our son to see an OT specialist to look at reasons why his PS may be so low. It has been suggested that he has auditory processing disorder. The school don't see this however, principally because he learnt to read incredibly quickly. The outcome of all this testing also showed he has dyspraxia and sensory integration disorder. A lot of labels !

I asked the pyschologists about calculating a GAI and she said that she had never heard of it. I didn't want to push the issue so thought I would do some research of my own, but despite looking through the technical report no.4, I can't seem to find a description of how to calculate it based on these numbers alone.

Is anybody able to help ?

many thanks, Jennie
