Since 1945, the Ecole Nationale d'Administration (ENA, French National School of Administration) has been training future executive officers of the French administration. Its original objectives still hold today: to open up recruitment to the highest levels of government service and provide a professional base to train civil servants in all areas and to develop a universal approach to public service. The School teaches students to work together in an inter-ministerial approach up to the highest levels of government service. Its objective is to train them in decision-making using exercises inspired directly by actual examples. Further, ENA has a Centre for Expertise and Research on Public Sector Administration (CERA). It also publishes the quarterly journal 'La Revue francaise d'administration publique'. The ENA actively participates in several European and international networks, think thanks and associations of good governance and research in public administration.
