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.
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.
Verbal and nonverbal memory is assessed via the Composite Memory Index, useful when a broad estimate of memory is desired.
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.
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.
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.
Items throughout the test have been updated to eliminate confusing or outdated content.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.
For most grade levels, T score ranges of at least 25 to 75 are available.
Whilst the RIAS-2 can only be administered by hand, it can be scored online via PARiConnect. All PARiConnect purchases made directly through ACER include dedicated local support. Contact our Customer Service Team to set up your account today.
