During the past four years, the interchange of teachers between the United Kingdom and the United States has received great impetus, and has been a remarkably successful program in building international understanding. Though the program got under way successfully before the war, exchanges before 1945 were limited for the most part to students and professors. With the inclusion of teachers, the base of the exchange program was broadened. The key position of teachers in every community provides wide opportunities for contributing to international understanding. Since the teachers exchange identical positions for an academic year, the two-way flow of ideas is insured. During the year abroad the teachers represent their country in towns and villages of another country. There they become a significant part of the community, where they learn the ways of another people. Upon their return they are in constant demand to explain the life and culture of the people with whom they have lived. This bulletin recounts the experiences of this interchange of teachers between the United Kingdom and the United States since the close of World War II. A selected reading list is provided.
