Another concern about Interchange surfaced during the Programme Review process was that Interchange is dominated by a small number of countries that participate heavily, while many others do not.
Interchange coordinators at the Graz meeting dug into the CISV International hosting plans, and concluded that the ten countries that host the most Interchanges also host at least 45 % of all CISV programs. So this tilt toward a few “Big 10” countries is a problem throughout CISV, not specific to the Interchange program.
A fair question is: Why is Interchange so popular in the countries where CISV is strongest? Is there a causal relationship there?
