Intellectual Classification Schemes

I know some of you are trying to cut through the diversity of classification schemas with a universal set of ranges and corresponding descriptors. Sattler (2008) provides valuable guidance in this regard by proposing qualitative descriptors that can be applied to Wechsler subtests (and other tests), using either a three-category breakdown with broader ranges or a five category breakdown with narrow ranges. Remember, scaled scores do not translate perfectly into standard scores. For example, classifying a scaled score of 8 as Average and a standard score of 88 as Below Average or Low Average is misleading. Another example would be classifying a scaled score of 12 as Average and a standard score of 112 as High Average or Above Average.
