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.”
