A modern and dynamic society cannot be built on a classical, unidirectional educational system. A modern engineer should have the ability to work with other specialists, in a common language in order to develop complex projects. This is why interdisciplinary relationships are so important in the educational process. The brief description of the engineers’ training programs in the "Politehnica" University, presented in this paper, reveals the progress we made to a modern educational system and the things to be done in order to get a healthy study program based on interdisciplinary relationships, discipline and exigency. The interdisciplinary issue in the educational process is the consequence of the exponential development of teaching matters leading to a different vision of reality and to hyper-specialization. This is the reason why we need a strong connection between different knowledge levels: interdisciplinarity.
