The Impact Evaluation Standard
The Impact Evaluation Standard (IES) is a proprietary framework designed to help UK organisations measure and value their social value activities.
The IES 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. Click here to learn more about Thrive.
