Correlations of Scores on the Gifted Evaluation Scale with Those on WISC-III and Kaufman Brief Intelligence Test for Students Referred for Gifted Evaluation

Abstract

29 students (M age of 8.0 yr.) who were referred for evaluation were administered the Gifted Evaluation Scale, the Kaufman Brief Intelligence Test, and the WISC-III. Paired t tests comparing the mean GES Quotient with the K-BIT mean IQ and WISC-III Verbal, Performance, and Full Scale IQs yielded no statistically significant differences (range of IQs = 120.6 to 122.9). While the significant correlation of the GES Quotient and WISC-III Performance IQ was .42, r = − .37 for the GES Quotient and WISC-III Verbal IQ. No significant correlation was found between the GES Quotient and the WISC-III Full Scale or K-BIT IQs. The limitations and implications of the study, with regard to the use of the Gifted Evaluation Scale, are discussed.
