This comprehensive test evaluates various aspects of cognitive functioning, including memory, attention, reasoning, and problem-solving skills. It is commonly used in educational, clinical, and research settings to provide valuable information about an individual’s strengths and weaknesses. In this introduction, we will discuss the components and purpose of the Woodcock-Johnson Tests of Cognitive Abilities and its significance in understanding cognitive abilities.
The Woodcock-Johnson Tests of Cognitive Abilities is a set of intelligence tests first developed in 1977 by Woodcock and Johnson. It was revised in 1989 and again in 2001; this last version is commonly referred to as WJ-III. They may be administered to children from age two right up to the oldest adults (with norms utilizing individuals in their 90s). WJ-III is praised for covering “a wide variety of cognitive skills.”
