Introduction: In the educational context, emotional and personality factors have been related to students' academic performance and quality of life; however, few studies have studied this relationship in depth in educational contexts where students have a high level of demand and competitiveness, as is the case of the students of the National Police Academy. Method: In order to study this issue in depth, a research project was carried out with the participation of 242 students who completed three questionnaires measuring aggressiveness (AQ), affect (PANAS) and personality (EPQ-R). Likewise, the grades achieved by the subjects in the sample at the end of police training were obtained in order to measure academic performance. Results: The results showed an inverse relationship between the dimensions of personality, psychoticism and conformity, and academic performance, even when the average levels of the group in these variables were low. Moreover, this relationship was maintained in theoretical subjects, but not in those involving practical components with physical content. Lastly, women showed higher levels of anger than men, and men showed higher levels of physical aggressiveness than women. Discussion and Conclusion: This data enables the establishment of a psychological profile of police school students that could help to optimize selection processes in a profession where situations with a high emotional impact must be managed.
