Austrian upper secondary school looking for partner school in Ireland, Netherlands, Denmark, Finland or Sweden

We are an accredited school looking for a partner school in IE, NL, SE, FI or DK for an English speaking project. We would like to send a class of 14-15-year-olds for about 5 project days. Host families would be a plus, however not required from our side. We are open to the topics of sustainability, democracy in school, intercultural skills and improving language skills. We are also happy to host.
