Christiane Stock, PhD, Head of Studies, Public Health, Unit for Health Promotion Research, Associate Professor, University of Southern Denmark, Esbjerg, Denmark presented at the 2015 International Conference for Health Promoting Universities and Colleges. Founded in 1995 with initially five network members, the German HPU network has since defined its goals and ways to support member organisations in their processes towards becoming a Health Promoting University. During the last 20 years the network has grown to more than 80 member universities and is now representing the largest network of Health Promoting Universities world-wide, and thus healthy working, living and learning environments for students and staff. Only a few studies have focused on evaluating the structures, processes and outcomes of health promotion networks, important for measuring goal attainment as well as analysing reasons for success and failure. The importance of evaluation was discussed and suggestions were made on ways to expand and enhance this network into the future of Health Promoting Universities in Europe.
