Could you help to calculate the Full Scale IQ and GAI ?

Thank you

I am not a specialist, but with 40 points between PSI and VCI a FSIQ is considered to be pretty much meaningless.

And while the gap between VCI and PRI is < 23 points I seem to remember something about spread between subtests making indexes invalid that make me wonder at the validity of your son's PRI, and maybe even his PSI.

Google WISC-IV Technical Report #4: General Ability Index.
Per that document I think your son's GAI would be 139.

Also not an expert but could he have eyesight or visual processing issues?

In fact the tester commented that my son is probably gifted but failed the PSI tests (coding) because of psychomotricity issues.
However I don't know how to interprate his results. If you can help me that would be great. Thanks

Oh my goodness, Dottie is back! :-)
