This paper analyzes the intervention of the military dictatorship in the average level of education. More specifically, we present two-dimensional analysis so far little explored in the field of research on educational change during the stage. On the one hand, the development of so-called "dual system" experience started in 1980 which involved a labor practice like mechanism of technical training of students. Try to see what were the main features of this system. At this point, we see how guidance, job training and the acquisition of certain skills of the workforce appeared as the average level tasks should take. To do this, we analyze the characteristics of the new method, the curriculum, the profile of apprentices and the distribution of school time. In parallel to this process, we will study the changes in the school disciplinary system, understanding that it is a central device that aims to shape the moral attributes of the labor force. Not only we will analyze the regulatory framework but also, we will approach the study of its particular embodiments. We will survey and analyze the national press and will investigate documentary file a public school in Buenos Aires. In short, we will discuss here three dimensions converged-the organizational level, the curriculum and discipline, that allow us to observe the links between educational reforms and capital needs during the last military dictatorship.
