Interchange is a family-centered, international exchange that usually involves one month visits in each of two consecutive summers. During the first year a delegation of ten young people (five boys and five girls) and an adult leader visit partners of the same age, gender, and general interests in another country for four weeks. The following summer, the delegation that visited first then hosts its partners for another four-week visit. In some instances an entire Interchange is completed in one summer, with consecutive three-week visits to each country.

The family plays a vital role in the Interchange Program. Each participant lives in the host partner’s home, allowing him or her to become a family member. This program enables not only the participants, but the entire family, to form lasting friendships and learn about another way of life, social structure and culture. Delegations experience typical family life and also meet for group activities throughout the month.
