Interesting. Our DS8 earned two 19s and two 18s on the subtests. I wonder how this would impact the interpretation of his test report, given that it was written 3-4 months ago.

I don't think it applies to all 18's, just the one or two rare 18's that are actually "ceilings" for that age range. I have some mild sour grapes myself, because although we have multiple 17/18 scores, we have no 19's whatsoever, so my kids' scores would stay the same while everyone else's increase, ROFL! I think my kids got hit hard on the higher ceilinged tests like vocabulary, for being more reserved than some GT kids. Then again, maybe my son really is only in that 140-150 range? I'm not sure why I wouldn't be "happy" with that,  . But yes, I believe acs is correct in that you need the raw scores to recalculate a total.

[quote=Dottie] I was surprised to learn that among the 2,200 cases in the standardization sample, only one child obtained a GAI score of 151 and none obtained an FSIQ score of 150 or higher. [quote]
I found this report too confusing on a quick glance. I wasn't certain if I would need raw scores for it to apply? I don't have raw scores, but in any case, I'm not sure the numbers mean much.
The only things that hit me forcefully was what you quote above. Wow! That's not many kids in the upper ranges. And finally, it clarifies again for me how ridiculous it is to try and make any sense of scores in the upper ranges. There just aren't any/many such scores in the norming sample, so there definitely isn't any further information for us to learn. There is no data comparing scores >150 or GAI's >150 in terms of rarity or *what it means* or anything else.
I see the wisdom in what someone told me on another list about scores in the upper ranges: really high scores the tell you that you have a kid whose IQ cannot be reliable measured by any current test. I think that's all we can know from these things and no "extended" scoring is going to help. What are the extensions based on? It's not like you could know how many kids in the country have since scored 3 19's on one area or FSIQ>150. So you can't make anything worthwhile out of a new number that is "175" instead because the SD=15 is worthless. There is no SD to a sample size of 2!
Am I missing something?
