It depends on what kind of school it is. If it is an institution of higher learning, that is, a regular public university (such as South China University of Technology), the Academic Affairs Office is the core department of the school and is in charge of teaching. Usually, the principal is the competent leader, and the main task of his director is to exercise specific things in teaching work. The school office is responsible for the day-to-day work of the school, which is generally served by the assistant principal, such as 1. Conference and event management. 2. Document drafting and review. 3. Guidance, inspection and supervision. 4. Comprehensive coordination. 5. Be responsible for the management and business guidance of party and government offices of various departments, research institutes, directly affiliated units and organs. There is no student office in colleges and universities, only the student office, which is responsible for student affairs.

If it is a high school, the director of the school office is responsible to the principal, and the specific duties are to be responsible for administrative affairs, the Academic Affairs Office is responsible for teaching work, and the Political and Educational Affairs Office is responsible for student work, especially ideological work. So it doesn't matter whether they are big or small, they are all clerks, depending on what you think.
