The Impact Evaluation Standard (IES) is a proprietary framework designed to help UK organisations measure and value their social value activities.

The Impact Evaluation Standard is a collection of metrics, proxy values and guidance documents designed in conjunction with a consortium of social value experts. It draws upon guidance from the UK government and a range of social value bodies and thought leaders.

The IES is aligned to the UK government’s ‘Social Value Model’ and PPN06/20. In additional to these, the IES includes a range of custom proxy values which allow organisations to convert the social impact they are creating into a financial value.

The IES is maintained by Thrive, a software platform to assist the collection, reporting and auditing of social value projects and initiatives.
