In upper secondary schools, those teachers who are the head of their department have an important role in educating students. Headmasters should have effective methods to manage department heads such as increasing their activity awareness, planning their activities, improving their skills, directing the combination between inside and outside school educational forces, organizing principal teacher staffs in fulfilling the contents of education, encouraging and rewarding for them for their activities, and testing and evaluation the activities of the department heads. Taking these steps would improve the quality of the department heads and lead to a better realization of educational goals.
