Some countries that have been visited include Germany, France, Canada, Czechoslovakia, Austria, Denmark, the Netherlands, Australia, New Zealand, China, Japan, Korea, Taiwan, Hong Kong, Italy, Greece, Fiji, the Republic of Ireland, the United Kingdom and Russia. Experienced alumni students looking to participate in the program again are given the ability to choose more exotic destinations for subsequent trips such as South Africa, or Antarctica. Programs typically depart between June and August, rather than during the academic year, in groups of between thirty and forty students with a target student teacher ratio of 10-to-1. Trips usually have students from a given city or county, not from a specific school. Tuition – the fees charged for a trip – range from $4,500 for trips to Canada to more than $7,999 for trips to Australia and the South Pacific. A trip to Antarctica was also available for $12,500, however this fee was not listed on their website and is no longer available.
