The Erasmus+ European project ECCOE – European Credit Clearinghouse for Opening up Education aims to support mobility in the European Higher Education Area by developing an “ECCOE-system” for the recognition of digital credentials. The project aims to increase trust in technology-enabled credentials among students, higher education institutions (HEIs) and employers. To this end ECCOE will develop and disseminate a set of operational tools such as descriptors and model agreements that institutional stakeholders need.
