Relationships of the WISC-R and K-BIT for an adolescent clinical sample.

Correlations between the Wechsler Intelligence Scale for Children-Revised IQs and the Kaufman Brief Intelligence Test were determined for a clinical sample of 44 adolescents (35 with learning disabilities, 9 with mental retardation) who underwent routine three-year reevaluations. Even though three years had elapsed between the WISC-R and K-BIT scores, the correlations among the total and subscale scores of these measures were high and were all statistically significant. A significant mean difference was found between the WISC-R Verbal IQ and its K-Bit counterpart, the Vocabulary subscales. Implications of findings for assessment specialists are discussed.
