´We took the statement quoted above from a text a nine-year-old boy with an immigration background had written at school after having participated in the Nightingale project for a period of eight months. Nightingale Berlin offers the opportunity to students to meet once a week with children from disadvantaged urban areas for joint leisure activities. The goal is to strengthen the children’s self-confidence and thus their interests, and to promote the students’ intercultural experiences. Because of the positive response to the project, Nightingale Berlin has expanded considerably during the last years, at present 3 schools and 54 student/child pairs are taking part; further expansion and a permanent setting for the project are in sight. The systematic, ongoing evaluation is to show the impact of this mentoring project on all participants involved, and in which areas a positive effect is shown. For this purpose, on a scientific level, questionnaires and interviews with students, parents, children and teachers were conducted and evaluated, with particular emphasis on children and students. According to the methodical principle of triangulation, i.e. based on a comparative analysis of different documents, various perspectives on the mentoring project and their interrelationship are illuminated.
