While detailed hands-on practice of court administration differs in each of country by its own tradition and constitution, general models of court administration can be classified according to who leads core parts of it among branches of government, such as executive or judiciary.
[1] Executive model entails core parts of court administration, such as annual budgeting and appointment of judges, to responsible minister (mostly justice, treasury or interior minister) in cabinet inside executive branch of the government.
Example of this model is Federal judiciary of the United States, where Judicial Conference constituted by chief judge of each federal courts makes policy decision, and Administrative Office composed by the Chief Justice executes it.
This model is popular in European countries, yet detailed mission of each 'council of the judiciary' varies.
For example, 'French council of the judiciary (French: Conseil supérieur de la magistrature)' on French judiciary courts is only responsible for human resource management but not for annual budgeting.
