Experimental Design
The goal of this study is to examine the effects of the CMS program on academic outcomes of Grade 9 KGS girls with and without the enhanced academic clinics. To estimate these effects, we conduct a stratified randomized controlled trial at the school level. We started with a sample of 201 schools from the 7 study districts in 3 provinces of Zambia that had at least 5 KGS Grade 9 internal students enrolled in the school, according to the KGS MIS data from May 2023. This sample of 201 schools was divided into 14 strata based on the district where it is located (7 districts) and Grade 9 enrollment (above and below the median number of internal Grade 9 KGS students enrolled in school year 2023, which is 18). Thereafter, schools within each of the 14 strata were randomly allocated to one of three arms:
1. Control arm (65 schools)
2. CMS treatment arm (70 schools)
3. CMS+ treatment arm (66 schools)
There was no baseline survey conducted for this study. Instead, we collected administrative data on student enrollment, attendance, and academic performance in Term 3 of 2023 to confirm that randomization was balanced.
The IE shifted from a study of CMS rolling out at the start of the 2023 school year (and outcomes measured at the start of 2024 school year), to the 2024 school year (and outcomes measured at start of the 2025 school year). This was due to the delayed start of the CMS.
The endline survey will be conducted during the 2025 academic year to examine the impacts of the interventions on KGS girls who were enrolled in Grade 9 during the 2024 academic year.
The original school sample (of 201 schools) was selected on the basis of Grade 9 KGS student enrollment in 2023 obtained from the MIS data for Term 2 of 2023 school year. By 2024, 26 of these original sample of 201 schools no longer had a Grade 9 KGS student enrolled. This was due to the phasing down of new cohort enrollment into the KGS program.
As a result, the study sample is now comprised of 175 schools:
1. Control arm (59 schools)
2. CMS treatment arm (60 schools)
3. CMS+ treatment arm (56 schools)
