This paper introduces the scope of, and rational for, engaging in advocacy work as part of development interventions. It then focuses on the issue of monitoring and evaluating these efforts – offering reasons why and when these processes should be planned and implemented, what’s involved, and who should be engaged in the process. It concludes by looking at some of the particular challenges and opportunities that the monitoring and evaluation (M&E) of advocacy work presents. It also offers some helpful considerations to those who are designing or implementing these processes.
