USIE (Unión Sindical de Inspectores de Educación) is the only existing education inspectorate trade union in Spain (state level organization). It was founded in 1978 and it is registered in the Ministry of Employment. The associates include education inspectors from the whole Spanish territory, which means that inspectors are civil servants working for the State within their own regional administrations. Every member participates in the organization through their own regional authorities (annual assemblies and executive committees). Through these assemblies, USIE’s administration is regulated and supervised.

It is a non-profit entity which aims at defending inspectors’ professional interests: representation facing public administrations, training, and counselling. USIE offers a specific, instructive programme which can be conducted either on-site or online. To do so, USIE organizes congresses and annual seminars with the collaboration of the Ministry of Education and the regional governments. Moreover, it counts with a virtual Campus that is fostered through an agreement with the International University of La Rioja (UNIR) and the Spanish Ministry of Education.
