The Gifted Rating Scales-School Form: A Validation Study Based on Age, Gender, and Race.

Steven I. Pfeiffer; Yaacov Petscher; Alper Tolga Kumtepe

This study examined the internal consistency and validity of a new rating scale to identify gifted students, the Gifted Rating Scales-School Form (GRS-S). The study explored the effect of gender, race/ethnicity, age, and rater familiarity on GRS-S ratings. One hundred twenty-two students in first to eighth grade from elementary and middle schools in the southeastern United States participated in the investigation. Results indicated high internal consistency for the six GRS-S scales: Intellectual Ability, Academic Ability, Creativity, Artistic Talent, Leadership, and Motivation. Results revealed no effect of race/ethnicity, age, or rater familiarity with the student. There was no significant effect for gender, although a trend was noted for girls rated slightly higher than boys across all scales. This trend was consistent with analyses of the standardization data and with cross-cultural findings using translated versions of the GRS-S. The present findings provided support for the GRS-S as a valid gifted screening instrument.

The Gifted Rating Scales–School Form (GRS-S), a teacher-completed rating scale, is designed to identify five types of giftedness and motivation. This study examines the reliability and validity of a Chinese-translated version of the GRS-S with a sample of Chinese elementary and middle school students (N = 499). The Chinese GRS-S was found to have high internal consistency. Results of the confirmatory factor analysis corroborated the six-factor solution of the original GRS-S. Comparison of the GRS-S scores and measures of academic performance provide preliminary support for the criterion validity of the Chinese-translated GRS-S. Significant age and gender differences on the Chinese GRS-S were found. Results provide preliminary support for the Chinese version of the GRS-S as a reliable and valid measure of giftedness for Chinese students.

ELBEP (Eliminating Language Barriers in European Prisons Through Open and Distance Education Technology) is a multilateral project funded by the European Union (EU) Lifelong Learning, Grundtvig (Adult Education) Programme. It aims to overcome language/communication problems between prison staff and foreign inmates at European prisons via online language teaching programs for the staff. This paper discusses the rationale and application of the project with an eye to the related literature and theoretical background. The project outcomes and findings can serve as an example for similar research studies.
