The WJ IV COG is carefully engineered to be the most contemporary and broadly used battery for an evaluation of strengths and weaknesses among cognitive abilities. The WJ IV COG is designed to maintain the cutting edge of contemporary assessment practice by moving beyond the initial specification of CHC theory with an updated model for interpretation of test results. This is based on recent research that informs the nature of the constituent cognitive abilities that are measured by each test and cluster. New tests and clusters are based on broad psychometric evidence and neuroscientific research. In its redesign, emphasis has been placed on the most important cognitive abilities. This cognitive abilities test is suitable for psychologists and others working in the field of intelligence and cognition. The WJIV is SASC approved.

The WJ IV is intended for use with examinees ages 2 through 90. Most examiners will need 5 to 10 minutes per test administered within a battery. Scoring is completed using Riverside Score.
