When I start working on a new impact evaluation, I often begin with a workshop in the country where the study will be conducted. The workshop brings together government officials, both at the central level and from the regions and provinces where the intervention will take place, other stakeholders such as NGOs or other UN organizations, and representatives of the research institution that will implement the survey. Part of the workshop is devoted to teaching or refreshing memories about evaluation techniques. This usually includes a section on randomization which we try to make interactive by doing a randomization game with the participants.
