The present investigation compared the Cognitive Levels Test (CLT) and the Wechsler Intelligence Scale for Children‐Revised (WISC‐R) scores for 55 children who were referred for remedial educational services. A comparison of the correlations for each of the criterion measures from the WISC‐R showed a consistent significant positive relationship with the CLT. A repeated measures analysis of variance that compared standard scores for the CLT with those of the WISC‐R indicated that significant differences existed between WISC‐R IQs and the CLT Cognitive Index. Implications concerning the validity of the Cognitive Levels Test are discussed.
