Adolescence is the transitional period between childhood and adulthood, characterized by a complex series of biopsychosocial changes, so the study is selected to assess the level of knowledge on antisocial behavior among adolescents in government and private schools. A comparative study was done among 60 boys of 15 to 18 years adolescents. Data was collected using a Self-structured multiple-choice questionnaire. The research analysis is done in four sections. Ultimately, the conclusion is that private school adolescents have more excellent knowledge than government school adolescents.
