CANIVEZ, Professor ofPsychology, Department of Psychology, Eastern Illinois University,Charleston, IL:DESCRIPTIONThe Woodcock Johnson IV (WJ IV) is a collection of three distinct individually administered testbatteries constructed to be consistent with Cattell Horn Carroll (CHC) theory of cognitive abilities(Schneider & McGrew, 2012).

7 The three batteries were co normed and include the Woodcock JohnsonIV tests of Cognitive Abilities (WJ IV COG), the Woodcock Johnson IV tests of Achievement (WJ IVACH), and the Woodcock Johnson IV tests of Oral Language (WJ IV OL). Oral language may beassessed in English and Spanish. The three batteries may be used individually or in any WJ IV is a major revision of its predecessor, the Woodcock Johnson III (WJ III; Woodcock, McGrew,& Mather, 2001, 2007), and includes national standardization. Normative data were produced by anationally representative standardization sample of 7,416 individuals between the ages of 2 and 90+years. The WJ IV includes an extensive technical manual with the largest compilation of statisticalmethods, detailed descriptions, and results this reviewer can recall detailing the development andpreliminary evaluation of the WJ IV.

8 The WJ IV was designed for use in clinical and educationalassessments as well as in research. After administering the measure, the examiner calculates the testraw scores and completes the Test Observation Checklist to then enter information into the onlinescoring and reporting system. Scoring and analyses are no longer performed by hand. Each of the threeexaminer s manuals includes training checklists to facilitate development of mastery of administrationand scoring prior to clinical WJ IV is a major revision of the WJ III, and development and revision goals intended to increaseadministration and interpretation options using the most up-to-date version of CHC theory and tests (eight) and cluster scores in cognitive, academic achievement, and oral language domainswere created (while others were eliminated) with a focus on increasing cognitive complexity (increasingcognitive information processing, demands on memory and attention control, and executive functioning)as well as facilitating measurement of relative strengths and weaknesses across domains.

9 In addition tonew tests being created, several tests had items added to the very low or very high difficulty range5 All Mental Measurements Yearbook test reviews are copyrighted by the Buros Center for Testing.

WJ IV content was reviewed by content experts and alsoexamined for potential bias. Empirical investigation of item bias (differential item functioning [DIF]) wasconducted across variables of sex (male and female), race (White and non White), and ethnicity(Hispanic and Not Hispanic) and reported in the technical manual.

10 Dichotomizing race into White andnon-White is problematic as non invariance might be observed in some racial groups but not others andcould be obscured by combining different groups into one non White category. Most items did notdemonstrate DIF, and of those that did, most reportedly were not included in publication WJ IV COG measures general intelligence hierarchically ordered above broad cognitive abilities(first order factors), which are measured by several narrow cognitive abilities at the subtest level. Assuch, the broad cognitive abilities (cluster scores) are inferences or abstractions from the observed testperformance on the narrow ability tests , whereas general intelligence (cognitive composites) is aninference from inferences or abstraction from abstractions (Thompson, 2004).
