In this article, the author reviews the Reynolds Intellectual Assessment Scales (RIAS), an individually administered test of intelligence appropriate for ages 3 through 94 years with a conormed, supplemental measure of memory. The RIAS should be administered by examiners who have formal training in assessment. In this regard, the RIAS is a restricted purchase product, and proof of training is required for its purchase. The RIAS can be used, for example, as a comprehensive measure of verbal and nonverbal intelligence and of global intelligence; as a measure of memory of meaningful verbal material and visual memory; and for the purposes of diagnosis of various childhood disorders (e.g., learning disabilities, mental retardation, and giftedness). Moreover, the RIAS can be useful for researchers who need a measurement of intelligence in their research design. The author finds the RIAS to be a reliable and valid measure of intelligence for children and adults and a nice addition to measures of intelligence presently available. Nevertheless, additional research in clinical settings is needed. The RIAS should be well received in the United States because of its sound psychometric properties, clinical and empirical utility, ease of administration, scoring, and interpretation, nondependence on motor coordination, visual-motor speed, and reading. The RIAS should be normed in other countries (e.g., Canada) to increase its applicability and appeal in other countries.
