The Relationship Between the WISC-III and the Kaufman Brief Intelligence Test with Students Referred for Gifted Evaluation

A tolal of 29 students (mean age = 7.96 yrs) who were referred for gifted evaluation in an affluent suburban school district in Western Pennsylvania were administered the Kaufman Brief Intelligence Test (K-BIT) and the WISC-III. Paired t-tests comparing the K-BIT mean IQ (120.59) with the WISC-III Verbal (123.65), Performance (118.86) and Full Scale (122.86) IQs yielded no statistically significant differences (t (28) = 1.49, p = .15; t(28) = -0.74, p = .47; t(28) = 1.35, p = .19, respectively). Correlational analyses indicated that the K-BIT and WISC-III Verbal (r = .35. p < .05), Performance (f = .35, p < .05), and Full Scale IQs (r = 53, p < .01) correlated significantly. The limitations and implications of the study are discussed.
