So having to predetermine the use of an alternate test, is that to prevent *tweaking* the FSIQ? BUt sometimes you might not know there is an issue until after the test. If you have two subtest scores A and B that differ by say 8 pts, you can't draw any conclusions. But say you also ahve subtest C in that same section which is supposed to be measuring the same thing, for ex: WMI, and that score is 1 pt away from score A, that leads me to believe that A and C are closer to that subtest index. no?
