12.4 Future directions and challenges in impact evaluation

Impact evaluation faces exciting changes and tough challenges ahead. New tech like AI and big data offer powerful tools for analysis, while participatory methods bring in diverse perspectives. These advances could revolutionize how we measure program effects.

But hurdles remain. Proving causality in complex interventions is tricky. Measuring long-term impacts within budget constraints is tough. As the field evolves, balancing scientific rigor with practical needs will be key for evaluators.
