What role does a 'deputy' typically play in an educational setting?

In an educational setting, a deputy typically plays the role of a supportive assistant to the principal. This role involves helping with administrative tasks, supporting school leadership decisions, and ensuring that the school's policies are implemented effectively. A deputy may also take on specific responsibilities, such as overseeing certain departments or initiatives and acting as a liaison between the staff and the principal. This position is crucial for the smooth operation of the school, allowing the principal to focus on higher-level leadership functions while the deputy manages daily activities and supports the educational environment.

The other options present various roles within a school but do not accurately capture the essence of a deputy's responsibilities. A deputy is not limited to substituting for teachers or merely coordinating clubs; instead, they have a broader administrative focus that supports the principal and the overall functioning of the school.
