This webinar, presented by Dr Jessica Horler of DataDrive2030, introduces a systems thinking approach to designing Monitoring, Evaluation and Learning (MEL) frameworks for early childhood (ECD) development programmes. It details the development and testing of an MEL toolkit with two ECD organisations, aiming to improve strategic understanding and readiness for evaluation. The discussion highlights how systems thinking enhances programme design by mapping interdependencies, identifying leverage points, and fostering adaptive learning. The toolkit is positioned as a practical resource for evaluators and non-profits seeking to strengthen evidence-based decision-making and accountability.
