What does the Woodcock- Johnson standardized test measure?
The Woodcock–Johnson Tests of Cognitive Abilities are a set of intelligence tests first developed in 1977.The last version is commonly referred to as the WJ IV.They can be given to children from age two up to the oldest adults.The previous edition covered a wide variety of cognitive skills.[4]
The Standard battery and the extended battery are included in the Woodcock-Johnson III tests of cognitive abilities.The Standard battery consists of tests 1 through 10 while the extended battery includes tests 11 through 20.There is more than one Woodcock-Johnson III Diagnostic Supplement to the Tests of Cognitive Abilities.It allows for a detailed analysis of cognitive abilities.Comprehension-knowledge, long-term memory, visual-spatial thinking, Auditory Processing, fluid reasoning, Processing Speed, Short-Term Memory, Quantitative Knowledge and Reading-writing are some of the broad abilities that this test examines.A general intellectual ability can be obtained.The BIA score is derived from three cognitive tests.The three cognitive tests measure an individual's verbal ability, thinking ability and efficiency in performing cognitive tasks.The BIA takes about 10 to 15 minutes to administer and is useful for screenings, re-evaluations that don't require a comprehensive intellectual assessment, or research that needs a short but reliable measure of intelligence.The WJ III Tests of Cognitive Abilities provide a more comprehensive assessment of general ability and the score is based on a weighted combination of tests that best represents a common ability underlying all intellectual performance.[5]
