3ie, in collaboration with RAND Corporation, launched the Registry for International Development Impact Evaluations (RIDIE) in 2014 to support overall improvements in the quality and integrity of impact evaluation evidence that informs policymaking and improving programming in low- and middle-income countries.



RIDIE is a prospective registry of impact evaluations of development policies and programmes in low- and middle- income countries. Researchers can register any impact evaluation that uses a counterfactual to estimate causal impacts. A prospective registry can increase transparency in the performance and reporting of research, minimising concerns over several well-known types of bias in research or reporting. Learn more about the benefits of a prospective registration

RIDIE serves researchers, professional evaluators, funders, journal editors, students, policymakers, and practitioners. Since the launch of 3ie’s Research Transparency Policy in April, 2018, we have made it mandatory for all 3ie-funded impact evaluation researchers to register in RIDIE. Find out whether you should register your impact evaluation study with RIDIE.

RIDIE is different from other recent initiatives to create prospective registries (such as the American Economics Association’s RCT Registry, the Experiments in Governance and Politics Network Registry, and clinicaltrials.gov) in a number of notable ways:

  • RIDIE allows registration of experimental and quasi-experimental studies, not just randomised controlled trials;
  • RIDIE focuses on evaluations in low- and middle-income countries;
  • RIDIE is restricted to actual programme evaluations, and does not include behavioral laboratory experiments; and
  • RIDIE aims to include all impact evaluations meeting the above criteria, not only scholarly research destined for journal publication.
