When used together, the three Woodcock-Johnson® IV (WJ IV™; Schrank, McGrew, & Mather, 2014) batteries (Tests of Cognitive Abilities [WJ IV COG], Tests of Oral Language [WJ IV OL], and
Tests of Achievement [WJ IV ACH]) are particularly useful for the assessment of dyslexia (Proctor, Mather, & Stephens, 2015), the most common type of learning disability.
Depending upon your state policies or school district practices, dyslexia may be referred to as specific reading disability, a specific learning disability in basic reading skills or reading fluency,
or a specific learning disorder with an impairment in reading (American Psychiatric Association, 2013). The International Dyslexia Association’s definition describes dyslexia as a specific learning disability that is neurological in origin, characterized by difficulties with accurate and/or fluent word recognition and poor spelling and decoding abilities, and is a result of a deficit in the phonological component of language (IDA, 2002). Tests and clusters from all three WJ IV batteries can be used to assess several key indicators and well-researched correlates of dyslexia.
