This report presents the findings of the impact evaluation (IE) of the five-year Her Choice programme (HC), conducted by the research partner, AISSR/UvA. The 'Her Choice' programme sought to build child marriage-free communities in rural communities in 10 countries: Bangladesh, Benin, Burkina Faso, Ethiopia, Ghana, Mali, Nepal, Pakistan, Senegal, and Uganda. The report draws on data collected during three phases of the programme: the baseline (2016), midline (2018), and endline (2020). The main questions this impact evaluation sought to answer were: 1. What has been achieved as a result of the Her Choice programme, and what lessons can be derived in relation to the intended outputs, outcomes, and impact? 2. How do different sets of programme stakeholders in the 10 programme countries view the effects of the five-year programme? The impact evaluation design is based on the Her Choice theory of change and programme indicators for programme outputs, (intermediate) outcomes and impact. We collected quantitative and qualitative data in treatment and comparison sites. To examine whether differences in the Her Choice outcome and impact indicators for single girls between endline (2020) and baseline (2016) were significant, we applied what is referred to as an unpaired t-test with equal variances in the data at baseline and endline levels.
