This paper examines clinical supervision approaches that have the potential to promote and implement effective teacher supervision in Nigeria. The various approaches have been analysed based on the conceptual framework of instructional supervisory behavior. The findings suggest that a clear distinction can be made between the prescriptive and collaborative clinical approaches of clinical supervision. The prescriptive clinical supervision is authoritative in nature while the collaborative approach is facilitative in nature. Based on the findings the research suggests that a collaborative clinical approach is applied to enhance effective teacher supervision. The collaborative clinical approach could furthermore foster an enabling environment that will enhance reflective practice and the long-term professional development of the teacher.
