Tyla Bishop hopes a trip to the United States in July will broaden her understanding of global food production.
Tyla (17), a year 13 pupil at St Kevin's College in Oamaru, is one of six TeenAg members from throughout New Zealand chosen to attend the 4-H Congress in Bozeman, Montana.
She lives on a 700-cow dairy farm in the Waitaki Valley and is working on another dairy farm during the summer holidays to help pay for the trip.
Pupils will stay with host families and explore Yellowstone National Park as part of the three-week exchange.
During the four-day 4-H Congress, the pupils will participate in educational workshops, listen to professional speakers and mingle with 400 other delegates.
