For a long time, there have been many reflections on the need for continuous improvement in universities. This is part of the certification processes regarding the quality that higher education institutions have to consider. On many occasions, it has been established some mechanisms that make it possible to carry out these improvements in the different processes; however, they have been done separately with a lack of systematicity of the information. In this work, it is broadly presented, the mechanisms that the National Autonomous University of Nicaragua, Managua (UNAN-Managua) has been carrying out to respond to the continuous improvement of education, very specifically to the process of postgraduate training, this being a key process to guarantee the training of professionals in different areas of performance, and the development of research competences that favor the implementation of problem-solving skills in their fields and environments in an integrated and quality manner. Likewise, it is shown the integrative vision with which the postgraduate improvement document has been designed. It respects institutional principles and strategies that respond to national guidelines that imply the search for good professional training.
