The Strategic Impact Evaluation Fund(SIEF)

The World Bank's Strategic Impact Evaluation Fund (SIEF) supports scientifically rigorous research that measures the impact of programs and policies to improve education, health, access to quality water and sanitation, and early childhood development in low and middle income countries. SIEF has funded around 80 impact evaluations in more than 30 countries. The majority of the evaluations are randomized control trials (RCTs), and they were chosen through a competitive process open to researchers worldwide. SIEF researchers must eventually make their data available for licensed and public use.

When available, the SIEF data collection hosts the baseline, midline, and end line data of the evaluations it has funded since 2012, along with their meta-data. For more information on these evaluations and any associated publications, please visit the evaluation pages of the SIEF website.
