Reynolds Intellectual Assessment Scales
The Reynolds Intellectual Assessment Scales (RIAS) is an individually administered test of intelligence that includes a co-normed, supplemental measure of memory. It is appropriate for individuals ages 3–94.
The RIAS intelligence subtests include Verbal Reasoning (verbal), Guess What (verbal), Odd-Item Out (nonverbal), and What's Missing? (nonverbal). Memory subtests include Verbal Memory and Nonverbal Memory. Included within the RIAS is the Reynolds Intellectual Screening Test (RIST), a quick screener that consists of two RIAS subtests (Guess What and Odd-Item Out) and takes less time to complete than the RIAS.
Subtests and test items
