This paper reflects the main results of ROSSINYOL project. This research, funded by the Catalan National Research plan, was focused on exploring how mentoring practices carried out within the Nightingale project are affecting educational aspirations and expectations of the mentees -usually children and youth from the more deprived neighbourhood and schools of different cities of the Girona province. Research team conducted more than thirty interviews in-depth to different educational agents involved in the mentorship: mentors, mentees, teachers and local authority staff. Results demonstrate how the impact is not only related to a change in educational aspirations and expectations of the mentees but also on the overall agents working with the child and youth. Impacts on other fields such as linguistic competences, participation in civic organizations or higher self-esteem were also observed.
