In this study, it is aimed to analyze how adolescents perceive the parental attitude and to what extent this perception affects their social competence. The study group has been composed of 613 high school students. Parental Attitudes Scale and Social Competence Inventory have been used as data collection tool. The data has been evaluated using SPSS 20.0 program. For the analysis of the data, Ki-Kare, Mann Whitney U test and Kruskall Wallis H Test have been used according to the results of the normality distribution test and uniformity test. As a result, it has been determined that the parental attitude that adolescents perceive is not affected by the variable of class level but it is significantly affected by the variable of sex; that adolescent girls perceive their parents as more democratic than adolescent boys perceive them. When social competence inventory scores have been analyzed, it has been determined that adolescent girls are good at conveying nonverbal and affective expressions when it is compared to the adolescent boys. Similarly, it has been determined that ninth-grader adolescents are less competent in terms of understanding and interpretation of non-verbal and affective expressions than upper classes. In general, it has been concluded that there is no meaningful relationship between adolescents' perception of the parental attitudes and their social competence level.
