The Kaufman Assessment Battery for Children (K-ABC) measures intelligence using simultaneous and sequential mental processes. This assessment is an individually administered measure of intelligence and achievement. Based on research and theory in cognition and neuropsychology, the K-ABC defines intelligence as a child's ability to solve problems using simultaneous and sequential mental processes. K-ABC measures intelligence separately from achievement. The K-ABC is designed for children ages 2 years 6 months to 12 years 5 months. The administration time for the K-ABC is 35-85 minutes.
There are sixteen subsets for the K-ABC:.
• Sequential Processing Scale: Hand Movements, Number Recall, and Word Order. The child solves tasks by arranging the stimuli in sequential or serial order. .
• Simultaneous Processing Scale: Magic Window, Face Recognition, Gestalt Closure, Triangles, Matrix Analogies, Spatial Memory, and Photo Series. The child solves spatial or analogic tasks by simultaneously integrating and synthesizing information. .
• Achievement Scale: Expressive Vocabulary, Faces & Places, Arithmetic, Riddles, Reading/Decoding, and Reading/Understanding. Measures acquired knowledge, including reading and arithmetic skills. Used in conjunction with the two mental processing scales, this scale is useful for evaluating a child's ability to apply mental processing skills to various learning situations. .
Reliability: The K-ABC was standardized on a national sample (2,000 cases) stratified for age, sex, race, region, parental education, community size, and educational placement ("Kaufman Assessment," 2003). .
Internal-consistency reliability: Mental Processing subtests: .62 to .92 (median .81); Achievement subtests: .70 to .95 (median .86); Global Scales: .84 to .97 (median .93) ("Kaufman Assessment," 2003). .
Test-retest reliability: Mental Processing subtests: .59 to .86 (median .
