Supplemental Product Resources

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.

Features and benefits

  • Assesses both verbal and nonverbal intelligence. Verbal intelligence is assessed by measuring verbal problem solving and verbal reasoning where acquired knowledge and skills are important; nonverbal intelligence is assessed by measuring reasoning and spatial ability using novel situations and stimuli that are predominantly nonverbal.
  • Includes a quick memory assessment. The RIAS provides a basic, overall measure of short-term memory skills (e.g., working memory, short-term memory, learning); measures recall in the verbal domain; and evaluates the ability to recall pictorial stimuli.
  • Fast. Administration of the four intelligence subtests takes approximately 20-25 minutes; administering the memory assessment adds only 10 minutes.
  • Screening version is available. Derived from the RIAS, the Reynolds Intellectual Screening Test™ (RIST™) consists of one verbal subtest and one nonverbal subtest. This brief screening measure takes only 10 minutes to administer and helps to quickly identify individuals who need a more comprehensive intellectual assessment or an intellectual reevaluation.

Test structure

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.

Technical information

  • Normative data are based on 2,438 individuals ages 3-94 years residing in 41 states, matched to U.S. Census data for age, gender, geographic region, ethnicity, and years of education completed.
  • To obtain clinical normative data, the RIAS was administered to 507 individuals representing 15 different clinical groups within the following categories: organic syndromes, mental retardation, learning disability/ADHD, and psychiatric disorders.

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.
