When you google, you could see what's in the WISC IV. Block design, matrix reasoning, etc... and the parent finding sample and showing the kid (although exercising/practiciing on those may invalidate the test result IMO) may have been fine.
But the 2 different vocabuary words transposing is a serious red flag. The website said you can buy WISC IV for $1069 from Pearson. I hope that they would demand the buyer is a qualified tester. You never know some parents may go out of their way to get their kids labeled PG/EG.
I personally do not care if MG kids became PG/EG by coaching but the resources are limited and it is a shame that some deserving kids not get the opportunities (like in NY).
