The RIAS is considered an IQ test - I kept reading the same comment about the 20-30 minutes to give the test - and then I found out that there are 2 different assessments....the RIAS - Reynolds Intellectual Assessment Scales and then the Reynolds Intellectual Screening Test (RIST - which is only a few components found in the RIAS)....my son took almost 2 hours to take the RIAS and that was with one break.
