Which levels of government use public administration?

In the study of public administration, this field is a fundamental feature of all nations, regardless of their specific political system. Within any given country, public administration is practiced across three primary levels of government:

• Central (or National) Level: This level oversees the implementation of policies and programs on a country-wide scale, often utilizing a professional civil service to manage internal affairs and provide technical support.1
• Intermediate (or Provincial/State) Level: Depending on the nation's structure, this level may manage regional administration. In some unitary states, provincial staff are considered part of the central civil service, while in federal systems like the United States, states maintain their own distinct administrative structures and civil services.12
• Local Level: This includes units such as counties, municipalities, townships, and special districts. These entities are responsible for delivering essential local services, though their specific authority and role are often defined by the state or central government.12

The relationships and coordination between these different levels of government constitute a significant and ongoing challenge within the practice of public administration.1
