This study investigated the construct validity of the Kaufman Assessment Battery for Children (K‐ABC) via correlational procedures with the WISC‐R. Thirty‐two special population children selected from kindergarten through grade five participated in the study; 19 children were diagnosed as learning disabled, 13 as educable mentally retarded. A high relationship between the WISC‐R FSIQ and the K‐ABC Mental Processing composite revealed evidence of construct validity in the measurement of intelligence. The K‐ABC diagnosed the learning disabled but failed to diagnose the mentally retarded children. The K‐ABC Sequential Processing Scale appeared to offer a unique construct (analytic, temporal sequencing) not measured by the WISC‐R. Implications for the usefulness of the K‐ABC are discussed.
