During three intense days, the Erasmus+ ACES project team met at the University of Alcalá (Spain), to work and reach a common understanding on the added value that the project can bring around the development of circular economy and accounting competences. After interviewing around twenty companies across Europe and conducting three different literature reviews on circular business models and management and financial accounting with a focus on the circular economy, the ACES project team has been able to identify the knowledge gaps that companies have and to learn about the advances gathered by the existing literature. At the meeting, the framework and elements of the upcoming ACES curriculum were discussed in depth. There was also room for a fruitful reflection on what kind of micro-credentials will be developed for people in working life. As the aim is also to make learning interesting, effective, and even fun, different pedagogical and facilitation methods were tested in the workshop. The aim is to use these methods also in the ACES pilot implementations and to get a practical idea of what kind of methods will be recommended in the final ACES pedagogical guide.
