Adolescents are a group of individuals aged between 10-19 years. Adolescence is considered a crucial period for individual development because, at this time, individuals experience biological, cognitive, and social transitions. Self-concept is a mental picture that a person has about himself, which includes physical and psychological images. This study aims to determine differences in self-concept between male youth who drop out of school and male adolescents attending school in Beiwali Village, Bajawa District, using a quantitative research approach with comparative techniques—testing the hypothesis in this study using the independent sample t-test.

The result of the hypothesis test is 0.011 (p <0.05), which means that there is a significant difference between the self-concept of male school dropouts and male youth attending school in Beiwali Village, Bajaw District.
