Our objective was to determine factors associated with violence against children at school in Peru. A secondary analysis of the National Survey of Social Relations (ENARES) of 2015 was carried out. Our sample consisted of 1559 primary school students, whose age ranged from 9 to 11 years old. Raw and adjusted prevalence ratios (PR) were estimated using Poisson regression with robust variance. Regarding domestic violence, it was found that having previously been victims of violence at home, living in a home where constant fights or arguments between parents or adults occur, and coming from a single parent family were all factors associated with a higher risk of violence. Meanwhile, the factors associated with lower risk of suffering violence at home included; that children age and become adults and classrooms with a higher proportion of females.
