The Kaufman-Assessment Battery for Children (K-ABC), a new individually administered intelligence and achievement instrument, includes several subtests on which the examiner may teach the task to the subject. The purpose of this study was to determine if teaching or training could influence the test outcome and thus, lower the reliability of the…

Discrepancies between the K-ABC and its theoretical base of simultaneous and sequential mental processing; technical and design problems related to disproportionate subtest contributions of the Simultaneous Scale to the Mental Processing Composite; the method of subtest-specific variance computation and use in interpretation; and utility with…

Three levels from the Kaufman Assessment Battery for Children (K-ABC) standardization sample were randomly selected and their subtest score intercorrelations were subjected to factor analysis. The analyses yielded minor inconsistencies which suggest the instrument does not primarily measure simultaneous and sequential processing and achievement as…
