This study analyzes the standardization sample of a new teacher rating scale designed to assist in the identification of gifted students. The Gifted Rating Scales-School Form (GRS-S) is based on a multidimensional model of giftedness. Results indicate no age or race/ethnicity differences on any of the scales and small but significant differences in favor of females on three of the six scales: Artistic Ability, Motivation, and Leadership Ability. Diagnostic efficiency statistics and receiver operating curve analysis support the validity of the Intellectual Ability scale in identifying intellectually gifted students. The Intellectual Ability scale was successful in both correctly identifying students with high IQ scores (test sensitivity) and correctly identifying students without high IQ scores (test specificity). The present findings extend the analysis of the standardization sample reported in the test manual and provide additional support for the psychometric qualities of the GRS-S as a valid gifted screening tool.
