Use of the Woodcock-Johnson IV Tests of Cognitive Abilities in the Diagnosis of Intellectual Disability


This chapter begins with an overview of the eligibility and diagnostic criteria for intellectual disability (ID), continues to discuss test and score properties that are important when assessing for ID, follows with an evaluation of the Woodcock-Johnson IV (WJ IV) Tests of Cognitive Abilities (COG) in terms of it addressing these properties, and ends with a case study. Evidence supporting the use and interpretation of the General Intellectual Ability and Gf-Gc Composite from the WJ IV COG is highlighted and evaluated, and applications of these scores to practice are presented.
