Information on the impact component of REF2021, including the relevant assessment criteria and FAQs.
The information on the impact component of REF2021 is taken from the Guidance on submissions (REF 2019/01) (GoS) and the Panel criteria and working methods (REF 2019/02) (PCWM) published by the REF team in January 2019. The documents were first published as drafts in July 2018 and underwent consultation before being finalised and published as Key documents. References below have been updated and refer to the final guidance documents.

Detailed assessment criteria for impact case studies
Reach will be understood as the extent and/or diversity of the beneficiaries of the impact, as relevant to the nature of the impact. Reach will be assessed in terms of the extent to which the potential constituencies, number or groups of beneficiaries have been reached; it will not be assessed in purely geographic terms, nor in terms of absolute numbers of beneficiaries. The criteria will be applied wherever the impact occurred, regardless of geography or location, and whether in the UK or abroad.
|Significance||Significance will be understood as the degree to which the impact has enabled, enriched, influenced, informed or changed the performance, policies, practices, products, services, understanding, awareness or wellbeing of the beneficiaries.||PCWM 289|
