This work explores the relationships between citizen training in education and the human development necessary for the formation of democratic citizens. The text also presents different controversies that revolve around the concept of citizenship in light of various theoretical conceptions, and a position is assumed that favors its application in educational proposals in an international context. Even revealing the sources that generate the conception of the formation of citizens throughout history presupposes analyzing the synergies that characterize the models of citizenship and the educational projection of each educational stage. The importance of reflecting on the rationality of pedagogical decisions includes an exercise to recognize the challenge that the new challenges of our time imply, from the training processes for the exercise of global citizenship.
