Soŵe sĐholars have attributed poor performance of students in academic to high level of indiscipline among students while others disagreed. Nevertheless, it becomes imperative in recent times that many schools have traded away discipline and as a result led to poor academic performance of students. This study was carried out to establish the relationships between schools discipline aŶd studeŶts’ aĐadeŵiĐ perforŵaŶĐe. The study eŵployed Đross seĐtioŶal researĐh survey design in which questionnaire was the main instrument of data collection in addition to interview guide and document review. Simple percentage and Chi-square statistical method were used to analyze the data. However, the findings of the study clearly showed that effective sĐhool disĐipliŶe should ďe eŶĐouraged iŶ ĐoŶtrolliŶg studeŶts’ ďehaviour thus affeĐts studeŶts’ general academic performance.
