Psychological Test

Name Kaufman Adolescent and Adult Intelligence Test
Purpose Designed  to measure both fluid and crystallized intelligence
Population Ages 11 to 85+
Score These six subtests comprise the core bttery of the KAIT and together yield the composite IQ , an index of general intelligence. The standard IQ scores have M= 100 and SD= 15. The standard scores of ten subtests have M=1- and SD= 3 and are called subtest scaled scores.


Time (58-73) minutes for core battery, (83-102) minutes for expanded battery

Description The KAIT includes two components, a core battery and an expanded battery. The core battery consists of a fluid scale, a crystallized scale, and six subtests, and takes about 65 minutes to complete. The expanded battery includes the core battery elements, as well as four additional subtests, and takes about 90 minutes to complete. The expanded battery also includes memory for block designs, a measure of visual processing related to fluid intelligence; famous faces, a test of cultural knowledge related to crystallized intelligence; auditory delayed recall; and Rebus delayed recall. The two delayed recall subtests provide a general measure of delayed memory.
Reliability and Validity Test-retest reliability coefficients ranged from .87 (fluid IQ score ) to .97 (Crystallized IQ scale). The sub test-retest reliability coefficients were below .80. Norms The normative sample included 2000 individuals ages 11 to 85 + years. The sample was representative of the US population census for gender, socioeconomic status, and race group
Suggested Uses  

The KAIT widely used with Wechsler scales of intelligence, (the Wechsler intelligence scale for children and the Wechsler adult intelligence scale ). The KAIT crystallized IQ has been shown to measure abilities similar to those measured by the Wechsler scales’ verbal intelligence factor. However, the KAIT Fluid IQ has been shown to measure abilities considerably different from those measured by the Wechsler performance factor, which is thought to be a measure of fluid intelligence.
