Delinquent children act out against society due to unmet needs and a lack of proper guidance and support systems. Juvenile delinquency refers to criminal acts committed by those under 18. Factors that can contribute to delinquency include hereditary and constitutional issues, problems at school like a poor curriculum or teachers, and troubles at home such as a broken family, criminal parents, or lack of freedom. Teachers can help prevent delinquency by educating parents, removing children from bad influences, improving the school environment, organizing group activities, channeling energy into useful work, and providing moral and religious instruction.
