In order to write competitive proposal for Horizon Europe funding, it is important to understand both theory (funding rules) and practice (concrete implementation of EU-funded projects) of the EU's framework programme for research and innovation. The workshop aimed to address these points by  delivering an introduction about Horizon Europe and its general rules for participation and eligibility. For gaining an in-depth view on the practical dimension, the following group exercise allowed trainees for a collaborative reading and interpretation of a selected Horizon Europe call. In a concluding step, the groups were tasked to draft first outlines for the impact section of their proposal that would target this call.
