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. 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.
