The Reynolds Intellectual Assessment Scales (RIAS) is an individually administered test of intelligence that includes a co-normed, supplemental measure of memory.[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 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.[1]

Subtests and test items[edit]

Verbal intelligence Description Non-verbal intelligence Description Composite memory index Description
Guess what Participants are given around two

to four clues to solve the concept or the object being described

Odd item out Participants must choose

which picture does not belong in a set of

five to seven pictures. It's a form of

non-verbal analogy that measures

spatial ability, visual imagery and other non-verbal skills.

Verbal memory Participants have to listen to,

memorize and repeat back a

series of sentences and

stories that are read to them.

Measures encoding, storing

and recalling aspects

of memory.

Verbal reasoning Participants must complete propositional statements that essentially forms a verbal analogy. This section measures verbal-analytical reasoning ability. What's missing Participants must figure out the missing element in an incomplete picture. Non-verbal memory Participants are shown a picture

for five seconds and then must identify the same

picture among a series of different set of pictures. Measures encoding, storing and recognition of visual stimuli.


Editions and uses[edit]

The test is currently in its second edition, published in 2015.[3]

Both editions are suitable for evaluation of intellectual giftedness,[4] and high scores are accepted as qualifying evidence for high IQ societies such as Intertel (min. IQ ≥ 135) and American Mensa (min. IQ ≥ 130).[5][6]
