Evaluation Support Scotland (ESS) works with third sector organisations and funders so that they can measure and explain their impact. Our aim is to make evaluation valuable, relevant and proportionate. Our website gives access to evaluation tools and support. We explain our work with funders to make reporting more useful and we share learning about the difference the third sector makes. Evaluation Support Scotland (ESS) was established in May 2005 and launched formally in January 2006. We are a registered Scottish Charity and a Limited Company. We are partially funded by the Scottish Government and generate our own income from our workshop and support programmes.
