Gifted and Talented Evaluation Scales2 (GATES-2)

Authors: James E. Gilliam, PhD / Olga Jerman, PhD

• Gifted and Talented
• Ages 5 through 18
• Individual Administration
• Qualification Level B

Description
The GATES-2 is an innovative, quick approach for identifying students who are gifted and talented. The GATES-2 has five updated and revised scales with 10 items each:

• General Intellectual Ability
• Academic Skills
• Creativity
• Leadership
• Artistic Talent

The GATES-2 was normed on a nationally representative sample.

Reliability and Validity

• Cronbachs Alpha values ranged from 0.96 to 0.98.
• Test-retest correlations ranged from 0.88 to 0.91.
• Interrater reliability correlations ranged from 0.78 to 0.93.
• Diagnostic accuracy studies indicate that the GATES-2 accurately differentiates students who are gifted and talented from those who are typically achieving (sensitivity = 0.84, specificity = 0. 70, ROC/AUC = 0.84).
