Randomised control trials (RCTs) can yield information about the effectiveness of agricultural extension and other development programmes, facilitating cost-benefit analyses and policy decisions under resource constraints. However, even after RCT design questions have been settled, a number of other practical challenges to successful RCTs remain. As a guide to those interested in applying RCTs more extensively, we outline several ethical, organisational, design and field-based challenges for RCTs, along with potential strategies for mitigating the challenges. We provide illustrations from our experience of an RCT of the Community Knowledge Worker programme, a novel agricultural extension model in Uganda.
