GCSP's core activity is the provision of executive education and training in comprehensive international peace and security policy for mid-career diplomats, military officers, and civil servants from foreign, defence, and other relevant ministries, as well as from international organisations. Participants in GCSP courses come from countries of the Euro-Atlantic Partnership Council, NATO's Mediterranean Dialogue, the Istanbul Cooperation Initiative, and beyond, including South and East Asia and Africa. In addition to its three long-term courses (each lasting from three to nine months) offered in Geneva, the GCSP also offers tailor-made courses in Geneva, New York City, Dakar, Amman, Baku, Addis Ababa, Yerevan and Sarajevo.
