Introduction: The current models in the study of giftedness such as the Triadic Interdependence define it as a favorable outcome of the interaction between intrinsic (intellectual capacity, creativity and motivation) and extrinsic (family, peers, and school) factors. Based on this, the purpose of this study was to identify and establish a profile of gifted adolescents that includes both intrinsic and extrinsic characteristics, as well as to analyze the relationships and the differences between these characteristics within the resulting group of the profile. Method: Participants were 666 students from a public school, age ranged between 12 to 18 years, and the mean of age was 14.77. Various statistical analyzes were performed such as Pearson's correlation, Student's "t"-test and ANOVA test to compare the possible similarities and differences between intrinsic and extrinsic characteristics of students identified as gifted. Results: 93 out of 666 students were found to meet the criteria established in the literature to be considered as gifted. The collected data allowed us to establish both a general profile of the group and a more specific profile based on feature grouping. In both cases it was possible to determine every group's homogeneity and heterogeneity with regard to the presence of intrinsic and extrinsic characteristics, as well as the relationships between them. Discussion: The findings highlight that although gifted adolescents are a heterogeneous population, which shares some intrinsic and extrinsic characteristics, they differ in others depending on giftedness degree, and this should be taken into account when designing educational programs that meet both their internal and environmental needs so they can develop successfully in higher education levels.
