Administered by the International Initiative for Impact Evaluation (3ie), the Registry for International Development Impact Evaluations (RIDIE) is a registry of impact evaluations related to development in low and middle income countries. RIDIE will register any development impact evaluation that rigorously attempts to estimate the causal impacts of a program, including but not limited to randomized control trials. It is intended to be a prospective registry in which researchers and evaluators can record information about their evaluation designs before conducting the analysis, as well as update information as the study proceeds and post findings upon study completion.
