The reality is that the WISC-III is a thoroughly outdated test. And regardless of your feelings about minorities and testing, the results are near-worthless for use in advocacy; the norms are now out of date so the figures are suspect (you might enjoy learning about the
Flynn effect, while keeping in mind that the WISC-III is now over two decades old); and it's also simply not as accurate of a tool because it doesn't have any of the latest advances.
If anyone is still using the WISC-III today, it's only because they want to save a buck. I can't find a decent rationale like there is for the continuing scattered use of the SB-LM. The WISC-III is simply an old test that shouldn't be used; and like it or not, when a person undertakes to do psychological testing for money, there are going to be expenses.
Psych testers can do whatever they like to pass along the costs of doing business to their customers, but it's just not right to test the children of know-nothing clients with an old, outdated test and no warnings.
