    3. Abstract The recent revision of the Leiter (Roid and Miller, 1997) has rendered the scale more comprehensive in domains assessed, and has greatly improved its psychometric characteristics. The Leiter-R assesses the global intelligence of children and adolescents who cannot be tested using traditional methods. Specifically, the new assessment targets individuals diagnosed with all types of cognitive disorders including communication disorders, hearing impairments, motor impairments, traumatic brain injury, attention deficit disorder, and some forms of learning disability.

    4. Abstract (cont�d.) This assessment tool is made up of two subdivisions comprised of 10 subtests each: the Visualization and Reasoning (VR) subdivision, and the Attention and Memory (AM) subdivision. Administration of the VR and AM Batteries provides clinicians, teachers and families with a comprehensive understanding of a child or adolescent�s cognitive functioning regardless of language or motor ability. The Leiter-R battery of 20 subtests plus four rating scales (parent, teacher, examiner and self-rating) are specifically designed to detect small changes in cognitive ability, such as those that might be seen after interventions, because the scaling is based on item response theory.

    5. Abstract (cont�d.) Since the scales are detailed, they can aid in early detection of cognitive deficits or delays, as well as accurate treatment and program planning. Another unique feature and a major advance over previous intelligence scales, is that the Leiter-R is culturally fair and focuses on cognitive strengths rather than cognitive limitations.
