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
|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

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
