Description:

The Woodcock-Johnson IV (WJ IV) is a collection of three distinct individually administered test batteries constructed to be consistent with Cattell–Horn–Carroll (CHC) theory of cognitive abilities (Schneider & McGrew, 2012).The WJ IV COG measures general intelligence hierarchically ordered above broad cognitive abilities (first–order factors), which are measured by several narrow cognitive abilities at the subtest level. As such, the broad cognitive abilities (cluster scores) are inferences or abstractions from the observed test performance on the narrow ability tests, whereas general intelligence (cognitive composites) is an inference from inferences or abstraction from abstractions (Thompson, 2004).

The WJ-IV ACH battery includes 20 tests measuring reading (8), mathematics (4), written language (4), science (1), social studies (1), humanities (1), and spelling of sounds (1) that are combined to produce six reading, four mathematics, four writing, and six cross–domain cluster scores. The most frequently used achievement tests are the 11 Standard Battery tests. There are three parallel forms of WJ-IV ACH tests (A, B, C) to minimize item exposure in repeated administrations.

The Standard Battery includes 10 tests, and the Extended Battery includes eight additional tests. General intelligence (cognitive composite) is estimated by either a Brief Intellectual Ability (BIA) score (Tests 1–3) that includes one test each of Comprehension–Knowledge (or Gc), Fluid Reasoning (or Gf), and Short–Term Working Memory (or Gwm); a General Intellectual Ability (GIA) score (Tests 1–7) that includes one test each of Comprehension–Knowledge, Fluid Reasoning, Short–Term Working Memory, Processing Speed (or Gs), Auditory Processing (or Ga), Long–Term Retrieval (or Glr), and Visual Processing (or Gv); and/or a Gf–Gc Composite (Tests 1, 2, 8, 9) that includes two tests of Comprehension–Knowledge and two tests of Fluid Reasoning. The core WJ IV COG is represented by the first seven tests from the Standard Battery and yields the GIA. Unlike the BIA where the three tests were equally weighted, the GIA is a weighted composite with tests possessing higher g loadings providing greater influence.
