This study aims to determine the characteristics of gifted students' perceptions of intelligence and the effective factors in the formation of these perceptions. The research is based on the explanatory sequential mixed-methods design. The research group consists of gifted students studying general ability in the fifth and seventh grades at Erzincan Science and Art Center. According to quantitative data of the study, the arithmetic means of the incremental theory of intelligence were higher than those of the fixed theory of intelligence on the basis of gender and grade level variables. However, qualitative data indicated that 9 (75%) of 12 students perceived intelligence as fixed.
