On April 5, 2023, a Twinning focus group was initiated by the Horizon Europe EPIBOOST project from the University of Aveiro, Portugal, with active contribution of STEPUPIORS Coordinator Dr Milena Cavic. Identifying the need to complement current official guidelines, the collaborative group aims to produce detailed real-world-experience based project management guidelines for future successful Twinning project applicants, by collecting data from multiple countries and institutions.
