This website from the International Initiative for Impact Evaluation (3ie) is a repository of impact evaluations that have been conducted on development programs in low and middle income countries.
The purpose of RIDIE is to be not only a repository, but to also provide transparency and allow for quality evaluation research to take place.
"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."
