TheReynolds Intellectual Assessment Scales (RIAS) is an individually administered test ofintelligence that includes a co-normed, supplemental measure ofmemory.[1] 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.[1] Included within the RIAS is theReynolds 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.[1]
The test is currently in its second edition, published in 2015.[2]
Both editions are suitable for evaluation ofintellectual giftedness,[3] and high scores are accepted as qualifying evidence forhigh IQ societies such asIntertel (min. IQ ≥ 135) andAmerican Mensa (min. IQ ≥ 130).[4][5]
