What does it take to work for an international organization and to succeed there? How can universities prepare their students for a career in international organizations? Answers to these questions come from in-depth studies at selected international organizations (EU, OSCE, ESA, UNEP, World Bank) and a comparative survey of degree programs and professional schools in the United States and Europe. The results are of interest to human resources managers at international organizations, faculty and program managers at institutions of higher education, and last but not least to students who aim for a career in international public service.
