Aim: To investigate and compare the Structure of vocational interest in gifted and non-gifted high school students, based on Tracey's Spherical Model in Shahre-kord. Materials & Methods: The method used in this descriptive study was causal-comparative. 400 participants were selected by using random sampling. data was collected using A Tracy's personal globe questionnaire. The data was analyzed using independent T- Test. Results: The results showed that in five scales of vocational interests, among eight basic interest types(social facilities, managing ,business detail,data processing & mechanical), there are significant differences in Lower prestige interest types(Quality control & basic services),Holland RIASEC Types(realistic, social, enterprising & conventional) among gifted and non-gifted students. The mean differences were higher in ordinary schools’ students but in two types of dimensional scales in gifted students (people/thing, data/ ideas) the means were significantly higher. Conclusions: According to the study, it can be concluded that despite the personality traits of gifted students, differences in their interests are only apparent in a few number of scales, due to different learning environments, uncommon styles of teaching, being under pressure by society & their family who suppress their interests. our recommendation for their teachers & family is attempting to identify student's interests as much as other educational dimensions.
