Significant efforts have been made to promote gender equality in higher education (HE) in Europe. Examples include the establishment of the Athena Swan Charter in the UK in 2005 and the 2019 launch of the Irène Curie Fellowship scheme by Eindhoven University of Technology. But which initiatives address broader diversity, equity, and inclusion (DEI) challenges in HE? And which are specifically focused on engineering education? This exploratory study aims to improve our understanding of the ways in which a set of European HE Institutions engaged in engineering education address DEI at an organisation level, and how this is communicated within the public domain. The analysis of online data provided by a purposive sample of institutions is guided by the following research questions (RQ): 1. How is DEI addressed and defined in institution-wide strategic frameworks? 2. How many institutions describe having an institution-wide DEI organization? 3. What specific policies around DEI are being developed, and what areas are mentioned, defined, and prioritized? 4. What structures and resources noted as part of their DEI activities are specific to engineering faculties and departments? 5. What engineering-specific DEI initiatives exist that are not available in the public domain or are not written in English? Our sample is composed of the host institutions of the authors of the paper, and represent different European countries: Belgium, Denmark, France, Ireland, Portugal, Switzerland, and the UK. The findings of this exploratory study will be used to inform the design of a large-scale survey to identify DEI practices across the SEFI community.
