The target population of our trial are high school students in their last year who are eligible for the scholarship. These are students who come from economically disadvantaged background. We are able to convince 31 high schools (most of the high schools) in one major city in Indonesia to participate in our trial. From these high schools, we identified around 1300 students who would be eligible for the scholarship based on information provided by the high schools. We conducted a baseline survey using online survey tools that students can use through their mobile phone with these students. 1281 students completed the survey. Then we did stratified randomization to allocate these 1281 students into one control and one treatment group. We stratified along household head income quartiles, initial intent to apply for any scholarship (low, medium, high), and knowledge about the particular scholarship we provide information on (low, medium, high, very high). The randomization allocates 628 students into control group, and 628 students into treatment group (25 students were dropped either because they were in small strata or because they were misfits in the stratified randomization process). We did not conduct clustered randomization (either at school or class level) because power calculation shows that we would not have enough power if we conducted clustered randomization. We only have one treatment group due to power concerns, too, and as a result we are not able to separate the effect of motivation and the effect of information. We evaluate the effect of these two channels combined.
A few weeks after the intervention is conducted with the treatment group, an intermediate follow up survey will be conducted with both control and treatment group (online survey that can be completed using mobile phone) that evaluates the students' intent to apply for the scholarship and the knowledge about the scholarship (who are eligible, how to apply). We will also track which students apply for the scholarship until the application deadline (August, 2023).
After all the outcome data are collected, we will conduct regression analysis to analyze the effect of the intervention on students' intent to apply for the scholarship, knowledge about the scholarship, and whether the student applies for the scholarship.
