A Precise, Efficient, and Clinically Responsive Measure of Intelligence. New normative update!
The RIAS-2 NU is a comprehensive measure of general intelligence (g), verbal and nonverbal reasoning, memory, and processing speed applicable across the life span. With an updated normative sample based on 2023 U.S. Census data, the RIAS-2 NU applies to a larger, more representative population. Its four-subtest core battery—Guess What, Odd-Item Out, Verbal Reasoning, and What's Missing—continues to provide a highly reliable estimate of g. Supplemental memory and speeded processing subtests further enhance clinical insight where needed.
Digital scoring required
All RIAS-2 NU administrations must be scored using PARiConnect. Hand scoring is not supported.
Key features of the RIAS-2 Normative Update
• Accurate - Reduced dependence on reading and fine motor skills results in a more precise measure of g.
• Broad - Used in the identification of intellectual disability, learning disabilities, giftedness, memory impairment, and neuropsychological conditions.
• Comprehensive - Use one instrument to measure general intelligence, reasoning, memory and processing speed in individuals ages 3 to 94 years.
• Efficient - Administer all eight subtests in less than one hour.
Features and benefits
• Updated normative sample of 2,793 cases based on 2023 U.S. Census data and consists of new concurrent measures (WISC-V, WAIS-5) and updated test-retest cases.
• Expanded acceptable alternative responses for the Guess What (GWH), Verbal Reasoning (VRZ), and What's Missing (WHM) subtests reflect modern terminology and user feedback.
• A new Profile Validity Index (PVI) provides information on the variability of an individual's subtest performance in comparison to others in the same age group.
• Updated Professional Manual, forms, and reports include information about the new PVI.
Administration and Scoring
All summary scoring and report generation is done exclusively through PARiConnect.
