Parent Ratings Using the Chinese Version of the Parent Gifted Rating Scales–School Form: Reliability and Validity for Chinese Students
Huijun Li, Donghyuck Lee, Steve I. Pfeiffer, and Yaacov Petscher
Abstract: This study examined the reliability and validity of the scores of a Chinese-translated version of the Gifted Rating Scales–School Form (GRS-S) using parents as raters and explored the effects of gender and grade on the ratings. A total of 222 parents participated in the study and rated their child independently using the Chinese version of the Parent GRS-S (CVPGRS-S). Results indicate high reliability for parent rating scores and statistically significant correlations between CVPGRS-S scale scores and students’ classroom academic achievement scores. The effect sizes of the relationships were moderate. Results revealed no statistically significant grade effect on any of the six CVPGRS-S scales; small but statistically significant differences in favor of females on the six CVPGRS-S scales were found. However, the effect size was small. Research results suggest that a Chinese-translated version of the GRS-S holds promise for use with Chinese parents.

The Gifted Rating Scales-School Form: An Analysis of the Standardization Sample Based on Age, Gender, Race, and Diagnostic Efficiency
Steven I. Pfeiffer and Tania Jarosewich
Abstract: 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.

Identifying Young Gifted Children Using the Gifted Rating Scales–Preschool/Kindergarten Form
Steven I. Pfeiffer and Yaacov Petscher
Abstract: This article reports on an analysis of the diagnostic accuracy of a new teacher rating scale designed to assist in the identification of gifted preschool and kindergarten students. The Gifted Rating Scales–Preschool/Kindergarten Form (GRS-P) is based on a multidimensional model of giftedness. An examination of the standardization sample using diagnostic efficiency statistics provides support for the diagnostic accuracy of the GRS-P Intellectual Ability and Academic Ability scales identifying intellectual giftedness, irrespective of the IQ cut score used to demarcate giftedness. The present findings extend the analysis of the standardization sample reported in the test manual and provide additional support for the GRS-P as a gifted screening tool.

The Reliability and Validity of a Korean-Translated Version of the Gifted Rating Scales
Donghyuck Lee and Steven I. Pfeiffer
Abstract: This study examined the reliability and validity of a Korean-translated version of the Gifted Rating Scales– School Form (GRS-S) and explored the effect of gender, rater, and grade. Data were collected from elementary schools in a metropolitan area and a midsize town in South Korea. In all, 49 elementary school teachers and 272 parents participated in the study; 257 students were independently rated on the GRS-S by teachers and parents. Results indicate high reliability
for both teacher and parent ratings and substantial correlations with students’ school performance. Results reveal no effect of rater or grade on any of the scales and small but significant differences in favor of females on four of the six GRS-S scales rated by teachers and five of the six scales rated by parents. The study provides preliminary support for a translated version of the GRS-S with elementary students in Korea.
