This article aims to present an analysis of the development of the level of perceived achievement of complex thinking competency in a group of business students at a university in Mexico. The intention was to identify the scaling of the competency and its sub-competencies during the training process and whether the students have the necessary skills to solve the problems and meet the challenges of their future environments. The study conducted exploratory and multivariate descriptive statistical analyses. The results showed that the participants perceived their achievement of the competency and its sub-competencies highly at the end of their training process and that the students scaled up their sub-competencies considerably.
