Yeah I know, and I wrote an e-mail today trying to persuade her to let us see the test report. In the meanwhile I am trying to extrapolate what her scaled scores might be based on the percentiles that I got.
I thought someone else might have gotten a similar percentile and then use the underlying scaled score to calculate GAI.
So far, I have gotten this far:
-Scaled score for PRI should be approximately 54 in order to yield 99,7 percentile.
-Scaled score of VCI should be approximately 42 in order to give 93rd percentile.
-Altogether SSS of 94-96 and thereby a GAI of 142-144?
Does that sound about right?
