TY - EJOU AU - Armstrong, A. John AU - Sullivan, S. Alice TI - Has DEI Increased the Representation of Women in Higher Education? A Time-Series Replication Analysis of the Impact of the UK Athena Swan Scheme T2 - Journal of Controversial Ideas PY - 2026 VL - 6 IS - 2 SN - 2694-5991 AB - Athena Swan is an award scheme designed to recognise higher education institutions’ (HEIs’) commitment to advancing ‘gender equality’. This paper uses time-series analysis to conduct a replication analysis of the relationship between Athena Swan status and both the proportion of women in senior roles and change in the proportion of women in senior roles. A previous study, using essentially the same data set, found that ‘Athena SWAN members showed greater and faster growth in female representations’. We apply time-series analysis methods to show that effects found in this previous study can be explained by two factors: (1) changes in the set of institutions that hold Athena Swan awards; and (2) the fact that it is more challenging to improve levels of female representation when they are closer to 50%. Once we controlled for these factors, we did not find any impact of Athena Swan awards on changes in the number of women in senior positions over the time-period studied. We conducted a power analysis which places bounds on the maximum size of effects which we would be unable to detect. In addition, we find that institutions with a low proportion of women in senior positions are more likely to be members of Athena Swan and are more likely to hold an award.
