(OSCE/Thomas Rymer) ODIHR supports OSCE participating States in their efforts to train nationals seconded to election observation missions. Throughout 2017, ODIHR contributed to courses organized by the German Centre for International Peace Operations, the Folke Bernadotte Academy in Sweden, the Solidarity Fund in Poland, the Central Election Commission of Kazakhstan and the European Inter-University Centre for Human Rights and Democratisation. ODIHR also provided briefings on its methodology at several academic workshops and events. Through extra-budgetary funding, ODIHR also provided comprehensive election observation training to broaden the pool of potential observers from participating States that do not regularly send election observers and, thus, are eligible under the Diversification Fund. ODIHR hosted two training courses for long-term observers, from 8 to 12 May and from 27 November to 1 December in Sarajevo. In total, 55 potential observers (22 men, 33 women) from 15 participating States, benefitted from the training. In all of its activities, ODIHR promotes co-ordination and collaboration with its international partners, as well as with citizen observer groups. This co-operation is crucial to ensure that interventions are complementary and that duplication of efforts is avoided. ODIHR continued to offer a free e-learning course for election observers, in English and Russian. Launched in 2012 for short-term observers, and enlarged with a component aimed at long-term observers in 2015, the course remains a useful resource for a wide range of people, from both governments and civil society. To date, over 7,500 people from more than 150 countries having completed the course. ODIHR has continued to join with partners from the OSCE Parliamentary Assembly, the Parliamentary Assembly of the Council of Europe, the European Parliament, the NATO Parliamentary Assembly and the Congress for Local and Regional Authorities in the delivery of post-election statements. Co-operation has also continued with citizen observer groups and various observer networks, including the Global INTERNATIONAL CO-OPERATION Network of Domestic Election Monitors (GNDEM). ODIHR also regularly engaged with international partners within the framework of the Declaration of Principles Group for International Election Observation, with a particular focus on follow-up activities and exchanging good practices. This included events organized with the United Nations, the Council of Europe, the European Union, International IDEA, the International Foundation for Electoral Systems and the Carter Center.
