The main aim of the Peer Mentoring Programme is for students performing well to support students that are struggling. This programme is aimed at students between the ages of 10 and 18, although it can also be developed with younger students (between the ages of 6 and 10). This tool can be applied in the context of a school cluster or in specific classes or school cohorts, according to the interests and availability of supervising teachers. This promising approach can support students in different situations of vulnerability or difficulty, engage students in different roles, and strengthen relationships in the school. Peer mentoring can also encourage students to offer mutual help, share difficulties, and provide help with learning to students from different school years. It encourages students to take responsibility, help each other and share knowledge.
