Universities are ranked in University League Tables (ULTs). Sustained academic criticism of the rationale and methodology of ULTs has not stopped these rankings exerting considerable pressure on the decisions of University managers. Widening Participation (WP) is not currently incorporated into ULTs, despite regulatory and ethical requirements for universities to diversify student intake. In this article, we explore how current ULT metrics for UK Universities relate to WP. Over 75% of league table metrics are negatively related to WP, so institutions with a diverse student body are significantly more likely to be lower down in the league tables. The worst relationship with WP is for entry standards. Universities who recruit high performing students are actively rewarded in the league tables; this fails to recognise that students with high entry grades are more likely to come from privileged backgrounds. We then develop a ULT which includes a WP score as an explicit league table metric. Our WP-adjusted table removes the negative relationship between WP and league table rank, and results in a somewhat fairer comparison between universities of different stated mission groups. We demonstrate how straightforward it could be to include WP in ULTs using publicly available data. We conclude that ULT compilers have an ethical duty to improve their definition of a ‘good’ university, which in the current UK HE environment must include WP. We believe this should be an urgent priority for the sector, so that Universities with a commitment to widening participation can be recognised and rewarded.
