TEEN VOLUNTEER ABROAD

International Volunteer Program for Teens Traveling Independently

Teen Volunteer Abroad is a program specially designed for teenage volunteers (ages 15-17) who wish to travel independently on a Cross-Cultural Solutions (CCS) volunteer program. In summer 2009, teen volunteers may choose from China, Costa Rica, Ghana, and Guatemala.

Teens will enjoy an action-packed 9-day or 2-week program, working side-by-side with local people at a CCS Partner Program in the community, enjoying Cultural & Learning Activities and other supervised trips to local markets and other sites of interest. 24-hour supervision is provided by English-speaking CCS in-country staff members trained to support teenagers living and volunteering in another culture.

WHO: Teens, ages 15-17

WHERE: China, Costa Rica, Ghana, Guatemala
