The Key Math Diagnostic Arithmetic Test was administered to 82 learning disabled adolescents. An analysis of the performance of these children revealed that: (a) mean LD performance peaked at approximately the fourth grade level of difficulty; (b) there was marginal variation in performance across the 14 subtests; (c) a strong negative correlation existed between years behind grade level and seven Key Math subtests; (d) the subtests factored into two ability categories, as opposed to the three suggested by the test developers; and (e) LD performance was quite distinct from that of normal children in terms of the types of computational errors made on the test.
