A descriptive survey research was designed to determine Botswana secondary school heads of agriculture departments' perceptions regarding the importance of their supervisory roles, levels of competence in performing the supervisory roles and their attitude toward supervision. A researcher developed, valid and reliable instrument was used to collect data. Findings showed that secondary school heads of agriculture departments had positive attitude toward supervision and they considered conducting meetings, planning, directing, coordinating, communicating, budgeting, delegating, and evaluating important competencies to possess in performing their roles. Findings, also, indicated that heads of agriculture departments were slightly competent in performing their supervisory roles. Meanwhile, attitude toward supervision, number of years in teaching, and age were substantial and positively associated with competence in supervisory roles. Positive and moderate associations were observed with respect to marital status, number of years as head of department, number of teaching staff supervised, and length of service before becoming a head of department. The effect sizes were mainly medium indicating a need to enhance competencies in supervision. The researcher recommends that an in-service training program be designed to upgrade agriculture teachers in supervisory competencies.
