A Response to Some Questions Raised About the Woodcock-Johnson: I. The Mean Score Discrepancy Issue.
Peer reviewedWoodcook, Richard W. – School Psychology Review, 1984
Twenty-one studies that reported mean score differences between the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) Full Scale are summarized. The differences are found to be minimal and are attributed to data bias and WJTCA's higher correlation with achievement. (EGS)
