Social capital is a very important value for the individual and society. While the presence of this value makes a positive contribution, many negative conditions are likely to occur in its absence. In this study, it is aimed to determine the social capital levels of the licensed athletes in the school team and the licansed students who are not in the school team and to compare them with demographic characteristics. For this purpose, the Turkish version of the Social Capital Scale of Primary School Students, developed by Huang (2008), was adopted by Ardahan and Ezici (2014) for secondary school students. The study group consisted of 198 students from 6th, 7th and 8th grades attending 4 different secondary schools in Islahiye, Gaziantep. As the obtained data showed normal distribution, in addition to descriptive statistics, Independent Sample T Test and One Way Variance Analysis were used. According to the research findings; A significant difference was found between the social capital levels of the students and being in the school sports team in favor of the licensed sportsmen students in all sub-dimensions of the scale. Although the social capital level of female students in the four sub-dimensions of the gender variable was higher than the male students, a significant difference in favor of female students appeared only in the Asking for Help from the Teacher sub-dimension. In general, there was no difference between the students in the grade level variable but there was a significant difference in favor of the 7th grade students in the Asking for Help from Friends sub-dimension among the students in the school team. According to these results, in order to improve the social capital levels of the students in the educational environment, it is suggested to create sporting environments where they can gather together only outside the environments they are in with academic concern and develop as a whole (cognitive, affective and psychomotor).
