Impact report Making a difference to people. Impact measurement and evaluation is key to helping us understand what works well and what not so well, enabling us to improve our work and ensure we are meeting the needs of the people who access our services. Every year we publish our Impact Report, which explains the work we have done and what we have achieved in the previous financial year. It is essential that we inform and share the impact we have on children, young people and their families. We want to show the effectiveness of our work in the children's sector to our partners and donors and it also helps us know what works well so we can use that evidence to continuously improve our services.
