Most actual law enforcement and day-to-day policing duties are delegated to local police departments on a city and county level which answer to the NPA but are considered agencies of their local government. However the NPA has direct control over several specialized units which may be deployed to assist local forces, as well as the national highway patrol.
Unlike the police system in USA, the central government appoints the head positions of city and county Police Departments in Taiwan and thus forms a solid chain of command for all police personnel. By calling a personnel review board, the Director-General of NPA has the full control of personnel rotation and transfer,
One exception is the President of the Central Police University, who is directly subordinate to the Minister of the Interior, and is not subject to the NPA personnel review board.
