The RIAS-2 retains all the features that made the original instrument so popular and gives practitioners even more reason to trust this instrument.

Fast -- Compared to similar measures, the RIAS-2 is faster as all eight subtests can be completed in less than one hour. Obtain a g score in less than 15 minutes.

Accurate -- A low emphasis on motor demand makes the RIAS-2 a more precise measure of general intelligence.

Affordable -- About half the price of similar measures.


Features and benefits

  • Can be used 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 as a way to determine educational placement.
  • Appropriate for private practice clinicians, child and school psychologists, and neuropsychologists.
  • An interpretive and score report are available on PARiConnect.
  • All four core and two memory subtests from the original RIAS were retained; however, individual harder and easier items were added to provide greater range, and other items were revised to allow for more up-to-date and acceptable responses.
  • Two supplemental speeded processing subtests (one verbal, one nonverbal) combine to create the Speeded Processing Index (SPI).
  • Requires low motor demand.
  • Optional memory and speeded processing subtests are available.
  • By popular demand, all basal and ceiling rules for the subtests are more conservative, are consistent with one another, and allow for more accurate assessment at the lowest and highest ability level.
  • Ability–achievement discrepancies with the Academic Achievement Battery (AAB) are provided. A combination kit is available.
  • If you need to administer remotely, choose either the RIAS-2 Remote or the RIST-2 Remote. Use minimally modified test materials and your videoconferencing platform to "meet" your clients where they are. 
  • The RIAS-2 Record Form with Spanish Responses is a culturally fair assessment that allows bilingual and English language learners the option of answering items in Spanish.
