Concurrent validity of the Cognitive Levels Test with measures of achievement for a sample of referred children and youth.

The present investigation compared the Cognitive Levels Test (CLT) with the Woodcock Reading Mastery Test (WRMT) and Wide Range Achievement Test-Revised (WRAT-R) for 55 children and youth who were referred for remedial/special education services. A comparison of the correlations for the criterion measures for the WRMT and WRAT-R showed a consistent significant positive relationship with the CLT. A repeated measures analysis of variance that compared standard scores of the CLT with those of the WRMT and WRAT-R indicated that significant differences existed between the test scores. Implications with respect to the concurrent validity of the CLT are discussed.
