It was also revealed that; principals’ supervisory, leadership and communication competences have significant composite influence on teachers’ work performance in terms of instructional delivery (p < .05; F = 26.764), attendance to classes (p < .05; F = 109.122), notes writing (p < .05; F = 228.118), and record keeping (P < .05; F = 468.793). Based on these findings, it was recommended amongst others that; such techniques as close supervision of teachers, good leadership styles, and effective communication should be jointly practiced by secondary school principals in order to improve teachers’ work performance.
