Resumen: Bullying is one of the most serious problems that education has, and one of the most serious problems of the educational system in this day and age. It affects almost all students, with them either being a bully, a victim of bullying, or a bystander. But it also has an important effect on the teaching staff, the schools themselves, and the educational system. For this research, we asked first- and second-year university students about their perception of bullying in their stages as students of primary and secondary education. To do this, we evaluated 654 university students: 195 men (29.82%) and 459 women (70.18%). These students were from eight different departments at the University of Zaragoza. The age of the participants ranged from 18 to 27 years, with an average of 22.54 years (s.d. = .292). The results showed that men tend to be bullies to a greater extent than women, and no relationship was found between gender and being a victim of bullying. In addition, it was found that nearly two out of every three students have experienced bullying during these stages of education and that almost all students (nine out of ten) have seen episodes of bullying. As a conclusion, we must point out the need for further studies and research work to discuss and analyze the phenomenon of bullying – a phenomenon that affects both students and our educational system.
