“Our organisation is fundamentally committed to the delivery of social value. We regularly collaborate with our public sector clients to determine the correct deliverables and reporting metrics, but we could not report these with confidence and ease without the adoption of the Impact Evaluation Standard”

About the Impact
Evaluation Standard

The Impact Evaluation Standard sets out a common list of metrics, proxy values and guidance documentation to assist public and private sector organisations in estimating and understanding the social value they are generating. 

It is, in essence, a common list of activities that organisations undertake which have a significant social, economic or environmental impact on their communities. The framework provides guidance on how to value and assess the social impact of all common types of these activities. 

The Impact Evaluation Standard leads the way in terms of measurement and reporting including integrated wellbeing and qualitative assessments to measure true impacts. From a reporting perspective it helps organisations differentiate themselves and bring robust innovation in the quantitative and qualitative assessment of social impact and value.
