Impact Evaluation of an Empowerment Pilot to Reduce School-Related Gender-Based Violence in Zambia 2024

Baseline and Endline

The study includes 90 secondary schools, from which 45 were randomized to control and 45 to treatment. Quantitative data collection included a school survey and listing exercise (not included in the package) conducted at the start of the implementation period followed by adolescent, attendance extraction, and teacher surveys administered four months after the intervention concluded. A listing exercise was conducted to identify the student sample for the adolescent survey. To generate the sample frame, we first extracted data from class attendance registers at the start of the study to compile a list of all students enrolled in grades 8 to 11. The impact evaluation was designed to measure the effect of the EP on the average student in study schools, rather than the impact on club participants specifically. Therefore, from each participating school, we randomly selected 25 boys and 25 girls, resulting in a random sample of 4,467 adolescents, about 20 percent of whom were KGS girls. In cases where a student was unavailable during the survey (about 30 percent of sampled students), enumerators referred to a ranked replacement list to interview an alternative boy or girl student from the same school. All remaining KGS girls not selected through random sampling were also surveyed, bringing the total sample size to over 6,100 students. To create a sample of teachers, we used convenience sampling to select one teacher from each grade between grades 8 to 12, for a total target sample size of 450 teachers.
