The piloting of good practice model 1 Comprehensive diversity training started in the cooperating four schools in Berlin, Germany. The first implementation steps comprised participatory needs assessment workshops and focus groups with learners to explore their views and perspectives on issues like commonalities and differences, diversity and discrimination, bullying, gender roles and inequalities. Four child-centred workshops were conducted by SPI Forschung with participation of 79 learners from 3rd to 9th grade in June and July 2017. After that 34 of them took part in focus group discussions. The participants were aged between 8 and 17 years and came from welcome classes for refugees and newly-arrived migrant learners or from multi-ethnic classes in primary and secondary schools.
