The need to identify and recognize school going children with giftedness remains a concern of the Republic of Kazakhstan's government. This concern motivated this study to examine the internal structure of the giftedness characteristic identification scale (GCIS) for use by Kazakhstan's school children. Exploratory quantitative research approach, and its design was grounded within the exploratory type. The GCIS is a self-report scale to identify the four characteristics of giftedness including contextual, intellectual, creative, and social giftedness. A total of 1176 elementary and middle school students were sampled for the study. The students were in grades and aged between 12 and 16 years. Most of the participants were 65% female; and 35% male. The data collected was analyzed using exploratory factor analysis. The findings established a relatively high-reliability Cronbach alpha coefficient of 89.7%. No statistical difference was found between the Kazakh and Russian languages of instruction, based on the gifted characteristics of the participants. Emphasis was placed on the fact that the GCIS was a reliable tool to identify giftedness among schoolchildren in Kazakhstan, but much future work is needed to determine its validity.
