While based on the same educational principles as CISV’s camp based programmes, Interchange encourages a deeper encounter between two cultures by placing young people within families. Group activities complement the intense in-depth family experience. Interchange takes place in two phases with one delegation visiting another country and then reciprocating by hosting the delegation from the country they visited. Not only is this a profound intercultural experience for the youth participant, but it also engages the whole family, and potentially the community in which they live, in the CISV experience. Delegations come from 2 countries and comprise 6 youth accompanied by a 21+ adult leader, and participants spend 14 days in each country.
