The study adopted a descriptive survey research design. The target population was 7,943 consisting of 7,886 boy students and 57 principals. The study drew a sample of 429 consisting of 366 students and 6 principals. Questionnaires were used to collect data from the students while the interview schedules were used to collect qualitative data from the principals. The main findings were that truancy and coupling especially in mixed schools as well as inability to pay school levies on time were the main institutional variables that negatively affected students’ academic performance in national examinations.
