<subfield code="a">School bullying is a phenomenon of unjustified aggression in the school environment&#xd;
that is widespread throughout the world and with serious consequences for both the bully and&#xd;
the bullied. The objectives of this research were to analyze the differences between the different&#xd;
bullying categories by gender and academic year in primary and secondary education students,&#xd;
as well as their relationship with academic performance. To categorize students according to their&#xd;
bullying experiences, the European Bullying Intervention Project (EBIPQ) Questionnaire was used.&#xd;
The Chi-square test was used to compare the scores obtained by the students in the EBIPQ based&#xd;
on gender and academic year, and the one-way ANOVA test was used to analyze its relationship&#xd;
with academic performance. Research participants were 562 students from the 5th (n = 228) and&#xd;
6th (n = 186) primary school years and the 1st (n = 134) and 2nd (n = 94) secondary school years.&#xd;
They were males (50.5%) and females (49.5%) ranging in ages from 10 to 15 years old (mean = 11.66,&#xd;
standard deviation = 1.206). The results showed statistically significant differences in gender and&#xd;
academic year, indicating a greater number of boys in the role of the bully/victim and girls in that of&#xd;
non-bully/non-victim. The most aggressive students were in the 2nd year of ESO (12–13 years old).&#xd;
Regarding academic performance, statistically significant differences were obtained that confirm the&#xd;
hypothesis that performance or average grade varies according to the category of bullying in which&#xd;
students find themselves. The academic performance of the non-bully/non-victim and those in the&#xd;
victim category was found to be higher than that of bullies and bully/victim students.</subfield>
