Each randomized evaluation (RE) is made possible through a partnership between researchers, organizations that run the programs to be evaluated (such as governments or NGOs), donors who fund the programs and evaluation, research centers who employ the staff associated with each evaluation, and research subjects who agree to participate. The social programs that the REs evaluate are often designed to target a certain population, for example, the poor or otherwise disadvantaged. The targeted populations of these programs are also the research subjects who participate in REs.
