The psychometric test results of a sample of 100 LD students with severe achievement problems were cluster analyzed. The variables included in this analysis were the subtests of the WISC‐R, the Bender Gestalt, the Benton Visual Retention, the Purdue Perceptual‐Motor, and the Lindamood Auditory Conceptualization tests. Using K‐means iterative clustering procedures, three clusters were obtained. The first cluster was defined by low scores on attention and concentration subtests; the second was defined by low scores on subtests of verbal‐associative intelligence; the third was defined by low scores on visual‐spatial and motoric subtests. Limitations of the study, in the scope of the psychometric testing and the lack of pediatric and neurologic diagnoses, are discussed.
