RIDIE

3ie’s Registry for International Development Impact Evaluations (RIDIE) aims to enhance the transparency and quality of impact evaluation research before it begins.

RIDIE is a prospective registry of impact evaluations related to development in low- and middle- income countries. Researchers can register any development impact evaluation that rigorously attempts to estimate the causal impacts of a programme, including experimental as well as quasi-experimental designs.

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

We encourage you to register any development-focused impact evaluation that uses rigorous methods to estimate the causal impacts of a program or intervention. Find out whether you should register your impact evaluation study with RIDIE.

About RIDIE

3ie, in collaboration with the RAND Corporation, has launched RIDIE with the core objective to support overall improvements in the quality and integrity of impact evaluation evidence in low- and middle-income countries, and thus provide a better basis for policymaking and improving practice. RIDIE serves several core user groups, including researchers, professional evaluators, funders, journal editors, students, policymakers, and practitioners. 

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.
