Gifted and Talented Evaluation Scales–Second Edition (GATES-2)
The GATES-2 is an innovative, quick approach for identifying students 5 through 18 years of age who are gifted and talented. Based on the most current federal definitions, the GATES-2 has 5 scales: General Intellectual Ability, Academic Skills, Creativity, Leadership, and Artistic Talent. Each scale has 10 items. New Features of the GATES-2 All new normative data were collected in 2013 and 2014. The demographic characteristics of the sample conform to those of the population reported by the 2013 U.S. Census Bureau. Twenty-two items from the first edition were retained and twenty-eight new items were added or revised. All new reliability and validity studies. The overall look of the test has been improved. Reliability and Validity Average coefficient alphas are .97 for General Intellectual Ability, .96 for Academic Skills, Creativity and Leadership, and .98 for the Artistic Talent. Test-retest coefficients range from .88 to .91. Intraclass correlation coefficients (ICC), used to measure interrater reliability, range from .78 to .93. Median correlations of the GATES-2 with criterion measures is .75. Diagnostic accuracy studies indicate that the GATES-2 accurately differentiates students who are gifted and talented from those who are typically achieving (sensitivity = .84, specificity = .70, ROC/AUC = .84).
