RIST™

Reynolds Intellectual Screening Test™

Purpose: Measures general intelligence quickly

Format: Paper and pencil

Age range: 3 years to 94 years

Time: 10-15 minutes

Two types of intelligence are measured

• The RIST comprises a verbal subtest (Guess What) and a nonverbal subtest (Odd-Item Out), which were selected from the RIAS using theoretical, empirical, and practical considerations.

• Guess What is a classic measure of crystallized intelligence, whereas Odd-Item Out shares characteristics with fluid intelligence.

• Both subtests have good psychometric properties and similarly good factor analytic and criterion-related validity evidence, and both can be efficiently administered and scored.
