Delinquent behavior among children and minors is an increasingly common problem both in the world and in Croatia and at the same time attracts the interest of both the professional and social public. Such behavior defines any form of behavior of a child or young person that deviates from established social norms and what is acceptable. Juvenile delinquency is a difficult and serious social problem and a challenge that a large number of psychologists, pedagogues and social workers face with on a daily basis. Such behavior may indicate that the child's behavioral disorders have been neglected at school, or even earlier, and have not been responded to in a timely manner and have far-reaching consequences. Namely, the child's behavior gives his reaction to family, school, friends and peers, thus asking for approval, support and help. The aim of this paper was to talk about this topic in an optimistic and realistic way and a theoretical analysis of what deviant behavior and delinquency are. The paper covered the fields of psychology, pedagogy and sociology, as well as segments of the sociology of juvenile education.
