The WJ IV ASB # 3: The WJ IV Gf-Gc Composite and SLD identifcation

I am pleased to announce that the WJ IV Assessment Service Bulletin # 3 (The WJ IV Gf-Gc Composite and its use in the identification of specific learning disabilities) is now available here. It will be posted at the publishers WJ IV web site within a week. Below is the abstract

The authors of the Woodcock-Johnson IV (WJ IV; Schrank, McGrew, & Mather , 2014a) discuss the WJ IV Tests of Cognitive Abilities (WJ IV COG; Schrank, McGrew, & Mather , 2014b) Gf-Gc Composite, contrast its composition with that of the WJ IV COG General Intellectual Ability (GIA) score, and synthesize important information that supports its use as a reliable and valid measure of intellectual development or intellectual level. The authors also suggest that the associated WJ IV COG Gf-Gc Composite/Other Ability comparison procedure can yield information that is relevant to the identification of a specific learning disability (SLD) in any model that is allowed under the 2004 reauthorization of the federal Individuals with Disabilities Education Improvement Act (IDEA).
