Abstract: This study examined the concurrent validity and diagnostic efficiency of the Kaufman Brief Intelligence Test (K-BIT) with 75 elementary and middle school students with learning disabilities, who had been referred for triennial multidisciplinary re-evaluations. High and significant correlations were found between the K-BIT and the Wechsler Intelligence Scale for Children-III (WISC-III). However, K-BIT Vocabulary-Matrices discrepancies were not in agreement with WISC-III Performance IQ-Verbal IQ discrepancies. Substantial agreement was found between the presence or absence of achievement-ability discrepancies identified by the K-BIT Composite and the Woodcock-Johnson Revised Tests of Achievement (WJ-R ACH) and those identified by the WISC-III full scale IQ and the WJ-R ACH. Results suggest that diagnostic precision can be maintained and time may be saved by utilizing a brief ability measure (K-BIT) as a substitute for a comprehensive ability measure (WISC-III) in the re-evaluation process of students with learning disability.
