The validity of a behavioral rating scale for identifying gifted and creative students was investigated for three ethnic groups by socioeconomic status. These groups were mid to high socio-economic status (SES) Anglo, low SES Anglo, and low SES Hispanic. The Scales for Rating the Behavioral Characteristics of Superior Students (SRBCSS) was studied to provide data about its utility in assessing giftedness. Data were examined to determine whether the SRBCSS differentially predicted scholastic achievement for different cultural or socioeconomic groups. Elementary school gifted Anglo and Hispanic students comprised the sample. All students were administered the Stanford Achievement Test (SAT). Regression analyses were computed between the SRBCSS and the SAT. Results indicated that the SRBCSS seemed to have minimal predictive validity for intelligence or achievement test performance by Anglo students. However, there may be value in its use in identification of gifted Hispanic students. The scale may also be useful in determining the differences in behavioral characteristics of giftedness among students of various sociocultural groups. (DWH)
