The Wechsler Intelligence Scale for Children‐Revised (WISC‐R) and the Woodcock‐Johnson Tests of Cognitive Ability (WJTCA) were administered in a counterbalanced order to 30 children referred for a three‐year reevaluation. All children were currently placed in an educable mentally retarded (EMR) program. The children ranged in age from 8‐0 to 12‐5 years, with a mean of 10‐6. The correlation coefficient between the WISC‐R and WJTCA was observed to be .72. Significant mean differences were found between the WISC‐R and WJTCA full scale standard scores. The implications of the findings are discussed relative to the placement of children in classes for the mentally retarded. Explanations for the mean differences between the WJTCA and WISC‐R also are explored.
