Agreeing with HappilyMom. I would not pay her until she produces a report that has been written to your satisfaction. And that would include a GAI score.
If there is a 62 point difference between his PSI and his VCI, the FSIQ is invalid. She should *not* report it.
The report should also include a statement that indicates that the GAI should be used where the FSIQ normally would be used. Here is an example:
Because this child demonstrated too much variability in his performance across the four index scores, the FSIQ is not an accurate representation of his intellectual ability. However, since his verbal and performance index scores were similar, the General Ability Index was computed. The GAI differs from the FSIQ because it is not influenced by performance on the working memory and processing speed tasks.
Or she could simply call the GAI the "General Ability Index/Full Scale IQ Equivalent" with no explanation. I've seen that done as well.
One other thing--If the VCI and PRI were extremely different from one another, the GAI may not be valid either. Perhaps someone with more experience can chime in here.
