Registry of Efficacy and Effectiveness Studies
This database provides a registry of causal inference or impact studies in education and the social sciences. The database accommodates a range of study designs, and researchers are encouraged to register their studies in the design phase. Eligible designs include randomized controlled trials, quasi-experimental designs, regression discontinuity designs, and single case designs. REES was developed to increase the transparency of and access to information about ongoing and completed impact studies in education and the social sciences.
