The scales for rating the behavioral characteristics of superior students (SRBCSS), which were developed by Renzulli and his colleagues, are considered the most widespread and the most important scales used in the identification of gifted and superior students. Recently, four new scales were added. The aim of this research was to examine the reliability and validity of the four new scales in the Saudi environment. The scales were administered in Riyadh city to 348 primary school children, and their validity was calculated in several ways: face validity, discriminative validity, construct validity, internal consistency, concurrent validity, and factorial validity. Reliability was calculated by Cronbach alpha and test-retest methods. Results showed that the scales have good psychometric characteristics, which render them suitable for use in the identification of the gifted in relevant scientific fields.
