Now available! The RIAS-2!
October 20, 2015
We are pleased to announce the release of the Reynolds Intellectual Assessment Scales™, Second Edition (RIAS™-2) by Cecil R. Reynolds, PhD, and Randy W. Kamphaus, PhD. The RIAS-2 retains all the features that made the original instrument so popular and gives practitioners even more reason to trust this instrument.

The revised assessment, which was developed by the original authors using feedback from clinicians around the country, remains true to the original test. It’s still fast, cost effective, and simple to administer and can be used across the developmental continuum to assess intelligence and its major components from ages 3 to 94 years.

 The RIAS-2:

  • Assesses both verbal and nonverbal intelligence. Verbal intelligence is assessed by measuring verbal problem solving and verbal reasoning, which uses acquired knowledge and skills. Nonverbal intelligence is assessed by measuring reasoning and spatial ability using novel situations and stimuli.

  • Optional memory subtests available. Verbal and nonverbal memory is assessed via the Composite Memory Index, useful when a broad estimate of memory is desired.

  • Yields a General Reasoning Index (GRI). A highly reliable score, the GRI reflects overall measurement of the general factor of reasoning and problem-solving skill.

  • Informs decisions in classification, selection, and educational placement. The RIAS-2 is ideal as a stand-alone intellectual assessment or as part of a clinical battery, when a standardized assessment of intellectual functioning is needed to diagnose specific disorders such as intellectual disabilities or learning disabilities, and for educational placement.


New in the RIAS-2

  • New speeded processing subtests and index. Two supplemental subtests (one verbal, one nonverbal) combine to create the Speeded Processing Index (SPI). Both the Speeded Naming Task and Speeded Picture Search subtests require far less motor skill than competitive measures.

  • Greater data for interpretation. Reliable change scores and ability–achievement discrepancies with the AAB are provided.

  • Revised basal/ceiling rules. Now all basal and ceiling rules for the subtests are consistent with one another and allow for more accurate assessment at the lowest and highest ability level.

  • Revised/new item content. Items throughout the test have been updated to eliminate confusing or outdated content. Guess What, Odd-Item Out, Verbal Reasoning, What’s Missing, Verbal Memory, and Nonverbal Memory subtests appear in this update, retaining the structure and familiarity of the original measure.

  • Wider range of T scores. For most grade levels, T score ranges of at least 25 to 75 are available.
