Examples of REF2021 4* impact case studies
Here you can find examples of 4* case studies from REF2021 submissions by Unit of Assessment (UoA). Whilst scores of individual case studies are not known, it is possible to determine scores when (near to) 100% of a UoA's 'impact portfolio' was assessed to be 4*.

Please note that a handful of cases linked below fell between the 3* and 4* boundary.

The guidance around REF impact remained largely unchanged between REF2021 and REF2014. Therefore, it can also be useful to look back at 4* impact case studies from the earlier exercise. Examples of REF2014 4* impact case studies can be found here.
