The ENI group (national engineering schools) is a network of five public engineering schools: ENI Brest (Enib), ENI Metz (Enim), ENI St-Etienne (Enise), ENI Tarbes (Enit) and Eni Val-de-Loire ((Enivl). At the end of their five years of study, ENI graduates are qualified industrial systems engineers, specialised in a particular field. The engineering degrees issued by the ENI group are accredited by the Commission des Titres d’Ingénieurs (CTI).

All of the schools in the ENI group train engineers in all fields. Thanks to their education in the field, they have access to every engineering profession: design, purchase, production, logistics, quality control, maintenance, IT, research and innovation. Each student is therefore free to choose the field which appeals to them: aeronautics, the car industry, sustainable development, medical imagery techniques, biomechanics, electronics, control engineering, energy, civil engineering, materials, video games, etc.
