This paper examines the effect of anti-social behavior on the academic performance of secondary school students in Nigeria. Character plays a significant role in human life, and negative behaviors among students often lead to poor academic outcomes. In many cases, such behaviors have resulted in the expulsion of thousands of secondary school students across the country. Anti-social behaviors such as vandalism, loud and disruptive conduct, verbal abuse, drug use, and damage to public property are increasingly common among students in Nigerian secondary schools. These behaviors are not only detrimental to school environments but are also a root cause of mass failure in both internal and external examinations. Each year, numerous students are expelled from their schools due to anti-social conduct and other related offenses. For example, in the previous academic year, twenty students were expelled from three secondary schools in Lagos State alone. Similar incidents have been reported in several other states across Nigeria, highlighting the widespread nature of this issue.
