Reynolds Intellectual Assessment Scales - Second Edition (RIAS-2)

SKU code: PG_RIAS2

Overview

Purpose: To assess intelligence and its major components

Age: 3–94 years

Time: 40–45 minutes

The Reynolds Intellectual Assessment Scales - Second Edition (RIAS-2) is an objective, comprehensive assessment of intelligence and its major components. With a low emphasis on motor demand, it offers a more accurate and valid assessment than similar measures.

Key Features

  • 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.

  • Informs decisions in classification, selection, and educational placement

The RIAS-2 is ideal as a stand-alone intellectual assessment or as part of a larger battery to diagnose specific disorders, such as intellectual disabilities or learning disabilities, and for educational placement.

  • 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.

  • 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Items throughout the test have been updated to eliminate confusing or outdated content.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.
