[QUOTE="InsaneCdn, post: 497487, member: 11791"] Others have covered the medication-effect side of things... IQ scores are not static. For anybody. The testing is set up for a "normally developing" child. But many of "our" kids have subtle developmental issues... Which means, the brain is developing unevenly. So... last time round, some areas of testing may have ranked higher than what she "really is", because she was developmentally advanced in those areas. Just because the comparative score has dropped, doesn't mean she has gone backwards. It more likely means that those areas have "normalized", and others are developing. Another interesting thing is that many evaluators are not aware of the fine-print in grading an IQ test. For the test to be valid as a comprehensive score, certain comparison points can't be more than a set number of points apart. If the spread is greater, the sub-tests are still valid but it [I]isn't possible to give an overall ranking of IQ[/I]. These big-spread scores happen in an estimated 2-3% of the population - so its not far-out unlikely or unreasonable... but just few enough that they don't have a way to normalize the scores. The full-scale number may well be invalid (I don't know the actual scoring rules). [/QUOTE]
