<< Objectives >>We want to foster direct and personal exchange about good practice in mobility between schools and organisations who are actively taking part in Erasmus+ exchange programs. This structured and pro-active dialogue will take place on organisational level but also via student focus groups, in order to include all perspectives and foster transparency, participation and inclusion as vital parts of sustainable school development.<< Implementation >>The adminstrative group, consisting of teachers, directors, adminstrative staff and persons responsible for transnational mobilities will meet virtually five times to discuss the various aspects of sustainability in mobility and school life. The student focus group will meet at least three times to share their perspective on the topic and formulate own expectations, ideas and suggestions. Inbetween virtual meetings national research and other preparatory measures will take place.<< Results >>The two groups will summarize their meetings and make transparent the discussion process and progress by publishing results of the meetings in adequate forms and depending on local availability. After the group meetings a summary of both processes will lead to the formulation of sustainable quality criteria on transnational mobilities. Those will be published locally, nationally and on European level in order to inspire as many stakeholders as possible to engage in sustainable mobilities.
