The authors replicated a study (White, 1979) in which high correlations were obtained among the Wechsler Intelligence Scale for Children‐Revised (WISC‐R), the Peabody Individual Achievement Test (PIAT), and the Goodenough‐Harris Draw‐A‐Man (DAM), and conclusions were drawn that all these instruments might not be necessary in the same test battery. The present study involved a larger sample (360 children). Much lower correlations among the instruments were obtained, although the pattern of correlation was similar. It was concluded that results of the White study may have overestimated the relationships between the variables because of factors unique to the sample. Test specificity appeared using the larger, normally distributed sample, suggesting a legitimate use of all three tests in a single battery.
