Description of the Test

The Kaufman Brief Intelligence Test, Second edition (KBIT-2) is a brief, individually administered measure of verbal and nonverbal intelligence that can be administered to examinees aged 4 to 90 years. The KBIT-2 was published in 2004, and is a revised version of the original Kaufman Brief Intelligence Test (K-BIT) which was published in 1990. The KBIT-2 can be used in a variety of clinical, educational, vocational and research settings. Some of the uses quoted for it are ‘screening to identify high-risk children who require subsequent in-depth evaluation’, ‘testing adolescent or adult job applicants to facilitate hiring or placement decisions’ and ‘measuring the intelligence of groups for research purposes’. Administration takes about 15 to 30 minutes. Because it is relatively easy to administer and all items are scored objectively, the test may be administered by suitably trained technicians and paraprofessionals, including qualified teachers or FE practitioners with NVQ level 3 and a further JCQ approved or similar qualification, including the Certificate of Competence in Educational Testing (CCET) in special educational needs. However, interpretation should be carried out by a psychometrically competent professional. The test comprises three subtests, two verbal and one nonverbal. The two verbal subtests, Verbal Knowledge and Riddles, measure verbal, school-related skills by assessing a person’s word knowledge, range of general information, verbal concept formation and reasoning ability. The nonverbal subtest, Matrices, measures the person’s ability to perceive relationships and complete visual analogies. Theoretically the verbal subtests measure crystallised ability and the nonverbal subtest measures an amalgam of fluid reasoning and visual processing. Three scores are obtained: Verbal, Nonverbal and the overall score called the IQ Composite. Age-based standard scores having a mean of 100 and a standard deviation of 15 are provided for the Verbal and Nonverbal domains and the IQ Composite. The normative sample comprises 2,120 children and adults from the USA. There is no UK edition.
