The Leiter-3 has two primary domains, a Cognitive battery made up of five subtests assessing nonverbal intellectual functioning and an Attention and Memory battery comprising five subtests. The latter battery is intended to aid in neuropsychological assessment and differential diagnosis for individuals suspected of attentional difficulties, learning disorder, or who have experienced a traumatic brain injury. For individuals with severe cognitive impairments, the measure also allows for the calculation of a Growth Score to compare results and...
