The norms become inaccurate over time, which is a big reason that the norms have to be updated every so often; it's not done just to cater to minority groups as you suggest. The WISC-III is about to become two revs out of date. In addition it's likely that many programs wouldn't accept such an old test-- Davidson doesn't, for instance. The tester simply shouldn't be using such an outdated, outmoded test, especially if there wasn't full disclosure up front.

The reality is that the tests are redone for financial reasons more than anything else. The companies selling testing material increase revenue every time they put out a new revision because it forces all the people giving the test to invest in a whole new set of testing material which usually sets them back 1000-2000 dollars depending on which test they are updating.

And yes some places will only accept the latest and greatest test for admissions, but that fact doesn't invalidate the older test for helping to identify a problem that a child has.
