A comprehensive and cost-effective intelligence test, the RIAS is a high-quality, reliable instrument that provides the necessary information to help clinicians make decisions regarding classification, selection, and educational placement. Individually administered, the RIAS includes a conormed, supplemental measure of memory and is ideal for use in both educational and clinical settings.
The RIAS includes a two-subtest Verbal Intelligence Index (VIX), a two-subtest Nonverbal Intelligence Index (NIX), and a Composite Intelligence Index (CIX), created by combining the VIX and NIX scores. The CIX assesses overall general intelligence (g), including the ability to reason, solve problems, and learn. A Composite Memory Index (CMX) is derived from the two supplementary memory subtests, Verbal Memory and Nonverbal Memory.
Foreign language versions available! The RIAS is also available in European Spanish and Danish. Contact our Customer Support Department at 1.800.331.8378 for information.
