Preface Looking to the future always requires a review of the past. The NA DAAD took the end of the 2014 – 2020 Erasmus+ programme period as an opportunity to conduct a comprehensive evaluation of participation in Erasmus+ cooperation projects within higher education in Germany. The aim was to take stock, but also to gain new insights into the motivations of higher education institutions (HEIs) for participating in the programme as well as into the effectiveness of the funding lines and our information and advisory services. These evaluation objectives help to identify any potential for optimisation of the NA DAAD’s advisory ser- vices and public relations, and to generate recommended actions for German HEIs and the EU Commission and/or its executive agency EACEA. The project started at the end of 2020 with initial interviews with HEIs. On this basis, an online survey among participating HEIs was conducted, followed by secondary data analysis, further interviews and focus group discussions. In addition to the project participants at German HEIs, senior experts, external evaluators and political stakeholders were also included. The resulting case studies provide an excellent illustration of the diverse potential impacts that Erasmus+ cooperation projects can have on the interna- tionalisation of HEIs, and of the synergies that can arise through creative use of the Erasmus+ portfolio in addition to the strategic planning of the HEIs and project consortia and pursuit of their own objectives. I would like to express my sincere thanks to all participants for taking the time to share their wealth of experience, expertise and reflections with us and the interested public. Otherwise, it would have been impossible to conduct such profound and comprehensive (and of course anonymised) analyses. I believe it was worthwhile in light of the findings! A complete presentation of the objectives, the evaluation questions and above all the results can be found in the evaluation report produced by the Technopolis Group, which was finalised in October 2021. This report forms the basis for the present brochure, via which we would like to share the most relevant results with you in a summarised way. Last but not least, I would like to thank our NA-internal respectively DAAD-internal project team who de- cisively contributed a great deal of expertise and commitment to ensure a successful project: Matthias Becker, Kathrin Herres, Florian Hillnhütter, Beate Körner, Britta Schmidt, Yvonne Schnocks, Elisabeth Tauch, Felixa Wingen, Katrin Winter (coordination). For their expertise and agreeable cooperation, I moreover express my gratitude to Nadia Galati, Maria Stalla, Dr Lisa Nieth and Dr Florian Berger from the Technopolis Group who implemented the evaluation and produced the final report. My thanks also go to the Federal Ministry of Education and Research for providing the financial resources for this project. Dr. Stephan Geifes, Director of the NA DAAD 1.
