Experimental Design
The study employs a two stage sampling strategy designed to generate a representative sample of schools, students, and caregivers in Khairpur district. At the first stage, 600 government schools were randomly selected from the district’s pool of 3,103 public schools, with randomisation stratified by taluka to ensure fair geographic representation across all eight (08) sub-district administrative units. Only functioning government schools with teachers and at least 04 students enrolled into grade 4 were eligible for selection.
At the second stage, four Grade 4 students were randomly selected per school—two boys and two girls—to ensure gender balance in the student cohort. For every selected student, the primary caregiver (typically a parent or guardian responsible for day to day educational decisions) was recruited as the corresponding adult participant. This process yielded a final intended sample of 2,400 students and 2,400 parents or caregivers, alongside head teachers from all 600 selected schools.
Stratifying by tehsil and a dummy variable that captured high parental engagement, schools were randomised into treatment or control group.
