"Having a refreshed, up-to-date and accurate theory of change (ToC) for each LEAP service—and the LEAP programme overall—is a priority for the LEAP Evaluation and Research team. This is because an accurate ToC is the blueprint for evaluation at service- and programme-level. While some services already have a ToC in place, taking the time to revisit and refresh your ToC is important. A ToC should be a working document; it is not meant to be static. It should evolve and develop to reflect a service’s learning and development. Our expectation is that services will either develop or refresh their ToC with our support. This is because services and service leads have in-depth knowledge about the domain(s) of early childhood development (ECD) associated with their service. Evaluators can work with services to review or develop their monitoring and evaluation approach, but first, programmes and services need to be clear about what outcomes and impact they want to achieve and why."
