The concurrent validity between the Woodcock‐Johnson Psycho‐Educational Battery‐Revised Tests of Cognitive Ability (WJ‐R, COG) (Early Development) and the Wechsler Preschool and Primary Scale of Intelligence‐Revised (WPPSI‐R) was examined. These two measures were administered in two separate sessions in counterbalanced order to 30 normal 3‐, 4‐, and 5‐year‐old subjects from the Midwest. Findings suggested that the WJ‐R Broad Cognitive Ability (BCA) and the WPPSI‐R Full Scale IQ (FSIQ) and Verbal IQ (VIQ) were significantly correlated, but that the mean BCA scores on the WJ‐R (COG) were significantly below the mean FSIQ scores on the WPPSI‐R by only ‐ 4.50 standard score points. No age or sex differences were found on either the WJ‐R (COG) or the WPPSI‐R. Significant correlations were found between the WJ‐R (COG) BCA and the following WJ‐R (COG) Broad Ability Factor scores: Long‐Term Retrieval, Short‐Term Memory, Auditory Processing, and one test called Picture Vocabulary representing comprehension‐knowledge. A significant correlation was also found between the WPPSI‐R Performance IQ (PIQ) and the WJ‐R (COG) Visual Processing cluster. Findings are discussed in terms of the theories of intelligence underlying each test. Implications for assessment of preschoolers under PL 99–457 also are discussed.
