The significant and progressive reduction in the number of permanent teachers in medical schools (professor, associate professor and assistant professor) is a reason for concern for the National Conference of Deans. This reduction will intensify in the coming decade (2017-2026). Forty-three percent of the permanent faculty will retire, as will 55% of the faculty linked to clinical areas, 34% of the faculty not linked to clinical areas and 32% of the faculty of basic areas. This deficit is significant now, and, in a few years, the situation wilt be unsustainable, especially in the clinical areas. This report reveals the pressing need to adopt urgent measures to alleviate the present situation and prevent a greater problem. The training of future physicians, immediately responsible for the health of our society, depends largely on the theoretical and practical training taught in medical schools, with the essential collaboration of healthcare institutions. Paradoxically, while the number of teachers decreases substantially, there is an exponential increase in the number of medical schools and students who are admitted every year without academic or healthcare justification.
