The Kaufman Brief Intelligence Test (K-BIT) is designed for use as a quick intelligence test for individuals aged 4 years through adulthood. The K-BIT measures both verbal and nonverbal intelligence, yielding Vocabulary, Matrices, and IQ composite scores. The test is easy to administer, and questions are scored objectively, making it easy for examiners who lack formal training in intelligence assessment to score the test. Data from the standardization sample and data in support of content, construct, and concurrent validity are all presented in the K-BIT manual. Because of the small sample size of the population aged 20 to 90 used in norming the test, it is recommended that scores for that population be interpreted cautiously. (SLD)
