The purpose of the Research Excellence Framework 2021 (REF2021) is to assess the quality of UK research and to inform the selective distribution of public funds for research by the four UK higher education funding bodies. The REF is managed by the REF team, based at Research England (RE), on behalf of the four UK higher education funding bodies. RE is part of UK Research and Innovation (UKRI), and under this arrangement UKRI has the role of ‘data controller’ for personal data submitted by us to the REF.
