In any event, measurement of HCS (hypothetical cognitive structure, i.e. IQ) is probably not an issue about which teachers should be overly concerned. While there are special instances when labelling a student might be advantageous, for the most part it is not. Teachers are generally more interested in what is changed by instruction, not in what is relatively untouched by it. РBiggs & Collis, 1982.
