The TEI peer tutoring program (in Spanish, Tutoría entre Iguales, hereinafter TEI ) is Spain's most important coexistence program for the prevention of violence and bullying in secondary schools and one of the first worldwide. So that we may better appreciate the effectiveness and benefits of this program, a comparative study has been developed between four schools that are presently following this preventive strategy (TEI centres) and four other schools that do not carry out the TEI program (non-TEI centres). Controlling the other sociodemographic variables, students' perception of coexistence, bullying and cyberbullying has been evaluated. In total, 1015 secondary school students belonging to eight schools from four autonomous communities in Spain participated. The results reveal that the students of TEI centres have a more favourable perception of educational coexistence and indicate lower rates of bullying and cyberbullying than those studying at non-TEI centres. These results highlight the benefits of the TEI program and the need to continue promoting and expanding these preventing bullying strategies in schools.
