This conference will be hold in Angers on 6, 7 and 8 July 2022 in the premises of the Western catholic University (Université catholique de l'Ouest), at the end of a project funded by Erasmus+ Strategic Partnership. The Alliance 3 project brings together European organisations from Denmark (Nyborg School), Spain (University of Vic), Hungary (Eotvos Lorand University) and France (Université catholique de l'Ouest, coord.) who have been working for several years on the issues of inequalities at school, inclusion and school dropout. It aims to create tools, knowledge and know-how for teachers, youth workers and parents to develop their collaboration in order to actively participate in the fight against ESL.
