Experimental Design
The study will be an RCT in 140 secondary schools in rural areas of the Amoron’I Mania region in Madagascar. The schools will be randomly assigned to one of 4 treatment arms:
1. Control (35 schools)
2. Infrastructure only (35 schools) – only construction of latrines and handwashing basins
3. Sensitization interventions + free sanitary pads (35 schools) – only Young Girl Leaders, teacher sensitization, school-based hygiene competition, and free distribution of menstrual pads. 2-6 girls are nominated in each school to be Young Girl Leaders.
4. The full package (35 schools) – combine all interventions from (2) and (3).
Hypotheses being tested:
• Effect of infrastructure. Understanding the impacts of the infrastructure by comparing arms with and without infrastructure is crucial for evaluating the overall cost-effectiveness of the program, since it is expected to contribute to about 60% of the overall cost. Measuring the psychosocial wellbeing effects of physical infrastructure is also crucial. Our qualitative work has indicated that in this setting, with very high rates of poverty and little state presence, having salient interventions in schools (visits from officials or construction of visible infrastructure) could have important effects on motivation and other psychosocial factors driving education, even if they do not target these outcomes directly.
• Effect of sensitization + sanitary pad interventions. Conversely, since the rest of the bundle of interventions is substantially cheaper to implement, finding that it is sufficient to generate learning effects could imply that it is very cost effective, competitive with the most cost-effective interventions described by a Global Advisory panel on education interventions (GEEAP 2023).
• Complementarity between infrastructure and other interventions. There may be important complementarities between the two types of interventions: for example, girls may only be able to change their hygiene behaviour and begin handwashing if they have access to handwashing basins at school. The 4th arm thus enables us to test this complementarity.
Data collection:
• Baseline (pre-intervention, October 2024), midline (after 1 year of intervention), and endline (after 2 years of intervention)
• Girls’ survey (17 girls per school) using surveys at the household of the 2,380 teenage girls and their mothers; teacher and director survey (maximum 3 per school); school-level survey.
In midline and endline, we also add approximately 4-5 girls per school to the sample who were potential nominees to be Young Girl Leaders (both in treatment and control schools, regardless of whether they were eventually trained), in order to measure causal effects on YGLs themselves.
