The Director serves under the Board of Governors, and is the school's chief academic and executive officer. Academic policies are decided by its Senate, which is composed of some professors and other representatives. The Senate controls and approves the curriculum, courses, examinations, and results. Senate committees examine specific academic matters. The teaching, training, and research activities of various departments of the institute are periodically reviewed to maintain educational standards. The Director is the ex officio Chairman of the Senate. The Deputy Director is subordinate to the Director. Together they manage the Deans, Heads of Departments, Registrar, President of the Students' Council, and Chairman of the Hall Management Committee. Deans and Heads of Departments in NITs are administrative postings rather than career paths. Faculty members serve as Deans and Heads of Departments for limited periods, typically 2 to 3 years, then returning to regular faculty duties. The Registrar is the chief administrative officer and overviews day-to-day operations. Below the Head of Department, are the various faculty members (professors, assistant professors, and lecturers).
