The Erasmus Without Paper (EWP) assessment report is part of the Interoperability Reinforcement Plan that was elaborated at the request of the European Commission in the summer of 2022. The plan sets out steps to reach full interoperability (which means the ability of computer systems to exchange machine-readable data among themselves) for inter-institutional agreements (IIAs) and learning agreements (LAs) as the highest priority. The aim of this assessment report is to help bring to the fore the successes as well as the known issues some higher education institutions (HEIs) are still facing when exchanging Erasmus+ student data via the EWP. The report is expected to improve the collective understanding of the state of play of the HEIs in the EWP ecosystem to move to completely digital IIA and LA processes. It should also lead to public discussion and greater transparency towards end users.
