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).
