It has always been important for volunteers to know that their involvement has made a difference, volunteering can also be of great benefit to the individual volunteer. Increasingly the focus is on providing the evidence to record, measure and showcase the impact of volunteering. As an example, the United Nations, in taking forward the Sustainable Development Goals 2030 agenda, is seeking to scale up the measurement of impact to evidence how volunteers are making a positive difference to solving the world’s problems. Everyone understands that impact measurement is important but not that easy to do. Learning from experience is helpful, organizations and institutions need to share information on what they are measuring and how they are doing it.
