Six very different schools from France, Turkey, Spain, Poland, Italy and Portugal, are gathered in the project ATLAS ("All Together Learning AT School") in order to get an overall view on problems of school integration. The main objective is to seek together solutions to these problems, relying on the teaching methods already experienced in each school. These solutions will be presented to partners during 6 meetings, analysed together and criticized. Every transferable element will be identified and it will lead to the implementation of new practices aimed at better answering the needs of the most underprivileged groups.
