The Kaufman Brief Intelligence Test (K-BIT) is a brief assessment of intelligence for individuals ages 4 to 90 that provides verbal, nonverbal, and composite scores. It estimates verbal and nonverbal abilities in about 20 minutes. The verbal scale measures word knowledge, reasoning, and general information while the nonverbal scale emphasizes inductive reasoning and visual processing through pattern and shape puzzles. Scores are derived through a series of verbal riddles and nonverbal pattern-matching matrix items.
