Meta-analysis was used to arrive at a quantitative synthesis of the results of 94 studies of the validity of Wechsler regroupings for differential diagnosis of learning disabilities. The primary findings indicated that no recategorization, profile, factor cluster, or pattern showed a significant difference between learning disabled and normal…
