Athena SWAN is a charter established in 2005 by the Equality Challenge Unit. It was originally set up to advance the representation of women in science, technology, engineering, maths and medicine (STEMM). In 2015 the charter was expanded to include staff in academic, professional and support roles and broaden the substantive areas to include arts, humanities, social sciences, business and law. The focus of the charter was also expanded to address gender equality more broadly not just barriers that affect women. It also saw the inclusion of intersectionality – which recognises that people can face discrimination based on different elements of their identity not just their gender – e.g. age, disability, race, religion and sexuality.
