A healthy school environment is undoubtedly a fundamental factor in the development of the teaching-learning process. In establishing the interpersonal relationships that naturally occur at school and in the classroom, good relationships are not always developed, since situations of conflict can arise, both between students and between the teacher and the students. There can also be situations of indiscipline, violence and mistreatment among colleagues. Such situations occur because school is for everyone and each person has their own way of being and behaving, although in their families and surroundings they don't always display the desired attitudes and behaviour. Education for healthy coexistence should be one of the school's major priorities, because it enables students to acquire personal and social skills that will enable them to integrate into the surrounding socio-cultural environment.
