Juvenile delinquency remains a pressing social issue in contemporary Nigerian society. Despite the existence of societal norms designed to guide behaviour, many youths engage in acts that contravene these expectations. Juvenile delinquency, defined as offences or misconduct committed by children for which they are deemed not fully responsible, has increasingly attracted public concern due to its growing prevalence. Studies indicate that delinquent behaviours among youths have reached alarming levels, posing challenges for parents, educators, and policymakers alike. Efforts to curb these behaviours, particularly through religious and moral education in schools, appear insufficient, as deviant tendencies persist among students. This study examines the phenomenon of juvenile delinquency among senior secondary school students in Nigeria, emphasizing the role of guidance and counselling in addressing the issue. By highlighting the causes, manifestations, and consequences of delinquent behaviours, the research underscores the need for proactive interventions within the school system. Ultimately, understanding and mitigating juvenile delinquency requires a combination of moral education, counselling strategies, and community involvement to foster responsible behaviour among youths.
