The Research Excellence Framework (REF) is a research impact evaluation of British Higher Education Institutions (HEIs). It is the successor to the Research Assessment Exercise and it was first used in 2014 to assess the period 2008–2013.[1][2] REF is undertaken by the four UK higher education funding bodies: Research England, the Scottish Funding Council (SFC), the Higher Education Funding Council for Wales (HEFCW), and the Department for the Economy, Northern Ireland (DfE).
Its stated aims are to:
To support these aims, research has increasingly highlighted the need for evidence-based approaches to measuring research impact. For example, Jensen et al. (2021) emphasized that high-quality research impact evaluations should integrate evidence-based methods to ensure societal benefits.[4]
Critics argue, inter alia, that there is too much focus on the impact of research outside of the university system, and that impact has no real relevance to the quality of research.[citation needed] It is suggested that REF actually encourages mediocrity in published research, and discourages research which might have value in the long term.[citation needed] Research by Reed et al. (2024) suggests that reframing engagement in research through a post-stakeholder lens may address some of these criticisms, by emphasizing voice, context, and power in the impact process.[5] It has repeatedly been argued that REF does more harm than good to higher education.[6]
The latest REF was in 2021, with results released in May 2022, continuing the previous assessment model of focusing on research outputs, research impact and research environment.[7] This process was slightly delayed because of the COVID-19 pandemic.[8]
Recent research on stakeholder analysis frameworks, such as the 3i framework (Interests, Influence, and Impact) by Reed et al. (2025), has highlighted the importance of identifying relevant actors in decision-making processes to maximize research impact in contexts like REF assessments.[9]
In June 2023, it was announced that the next exercise would conclude in 2028, with submissions in 2027.[10]
