The data were collected through Perceived Competence Scale, Scale for School Engagement and Short Form of Inventory Parent Attachment and Demographic Information Form. In this descriptive study, stepwise multiple regression analysis was used to determine the predictors of academic competence and social competence. According to the analysis results, internal engagement, program engagement, communication with mother, teacher engagement and trust to father significantly predict academic competence. However, internal engagement, trust to father, communication with the mother and administration engagement significantly predicted social competence.
