Help Me Calculate the GAI for WISC-IV - 04/04/11 12:07 AM
Help! My DS took the WISC-IV. Because of variations between his indexes, the psychologist thought that GAI would best represnt my DS abilities. Unfortunately, I am not sure that she calculated the GAI correctly based on what I am reading on-line in the WISC-IV Technical Report #4.
Can someone please help me determine what his GAI score would be?
His verbal comprehension scaled scores were as follows:
Similiarities - 14
Vocabulary - 11
Comprehension - 15
(Information) - 12
VCI Sum of Scaled Scores - 41
His perceptual reasoning scaled scores were as follows:
Block Design - 16
Picture Concepts - 15
Matrix Reasoning - 19
Perceptual Reasoning Sum of Scaled Scores - 50
I calculated a sum of scaled scores of 91 which translates to a GAI of 138 per technical report #4. However, the psychologiest has calculated a GAI of 134. A GAI of 134 is not even listed in the table in Technical Report #4.
I tried to politely ask the psychologist about this because initial the report listed two different GAI scores - a 134 and 135. I even referenced the Technical Report #4, but she said that the 134 is correct.
Please help...I spent a lot of money on getting the WISC-IV test done and I want to make sure that the report is accurate. I also want to make sure that the county takes the psychologist report seriously and feel like they wouldn't if there is glaring error in the report.
Thanks!
