The Woodcock-Johnson III (Woodcock, McGrew, & Mather, 2001) consists of two conormed batteries: the WJ III Test of Cognitive Abilities (WJIII COG) and the WJ III Tests of Achievement (WJ III ACH). When used together, these batteries provide a comprehensive framework for evaluating and exploring the relationships and interactions among cognitive abilities and academic performance for individuals between the ages of 2 and 90+ years. The WJ III is based on the principle of selective testing; the examiner administers only the tests most relevant to the referral questions.
