[4] The National Institute of Public Administration was established by order of minister-under secretary of the presidency, Luis Carrero Blanco, on 22 September 1958.

In this order, the Office of the Prime Minister ratified its condition as the government department responsible for the civil service, and it created within the Technical General Secretariat the Centro de Formación y Perfeccionamiento de Funcionarios (CFPF) (English: Training and Improvement Center for Civil Servants).

This name would evolve into the current National Institute of Public Administration (INAP), which was officially established in 1977.

[7] A decade later, in 1987, the Institute for Local Government Studies, founded in 1940, was merged into the INAP.

[8] In December 2023, a royal decree-law transformed the INAP into a state agency.
