The present study examined the concurrent validity and diagnostic efficiency of the Kaufman Brief Intelligence Test (K-BIT). Seventy-five students with learning disability were administered the K-BIT, Wechsler Intelligence Scale for Children-Third Edition (WISC-III), and Woodcock-Johnson-Revised Tests of Achievement (WJ-R ACH) as part of their triennial reevaluation. Correlations between the K-BIT and the WISC-III ranged from .18 (r2 = .03) to .82 (r2 = .67), M, = .62 (Mr2= .38). High levels of agreement were obtained between the K-BIT and WISC-III in identifying severe achievement-ability discrepancies on the WJ-R ACH. The K-BIT appears to be a promising general intellectual screening instrument when more comprehensive assessment is not possible or needed.
