Measuring IQ has an extremely narrow utility in general, and is rife with problems of measurement, to the point that people struggle to see correlations when we are talking about primary education. But even disregarding that, it is philosophically problematic to think along these lines. People learn and know things in an absolute plurality of ways, and in ways that can only be measured with very limited means; there is more than one way for someone to skin the cat of learning. In general, an absolute Platonic ideal of intelligence, which IQ enthusiasts implicitly rely on, is the thing that got us in this mess pedagogically.
