The Dean–Woodcock Neuropsychological Assessment System (DWNAS) provides a standardized procedure for assessing an individual's sensory, motor, emotional, cognitive, and academic functioning for both English and Spanish speakers, based on the Cattell–Horn–Carroll Model (CHC).
A fundamental element of the DWNAS is that it provides both a clinical neurological and empirical theoretical base (CHC) to assessment.
Multiple cognitive functions necessary in neuropsychological assessment are offered by the WJ-III or the Bateria III.
The Dean–Woodcock Structured Interview and the Dean–Woodcock Emotional Status Examination provide information regarding the patient's history and current psychological and medical functioning.
The advantage is that it makes the battery much cheaper, less time-consuming to administer, and potentially less tiring and frustrating for the examinee.
