Measure Intelligence and use Results for Educational Placement


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.

We recommend transitioning to the RIAS-2.

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.


Available in other languages

  • The RIAS materials, including the manual, have been translated into European Spanish and designed especially for Spanish-speaking clinicians and their clients. All normative data were collected in Spain. Certain test items and stimuli in this translation may vary from the English version because of cultural and linguistic differences between the countries and their language. The screening version, the RIST, has also been translated and normed with a Spanish population. Learn more or order.
