Before
There are eight partners in charge of implementing the program’s pilot, all chosen by the government. In the first pilot year (2016/2017), BRAC is managing 20 schools, Bridge International Academies 22, the Liberia Youth Network 4, More than Me 6, Omega Academies 19, Rising Academies 5, Stella Maris 4, and Street Child 12.
Based on criteria established by the evaluation team, MoE, and operators, 185 PSL-eligible schools were identified. 92 schools across 12 counties were randomly selected for treatment. Each treated school will be administered by one of the eight private operators. Since each operator has different criteria for the schools they are able to administer, each school submitted a set of criteria necessary for their schools. Based on these criteria, the universe of 185 experimental schools was split into 8 mutually exclusive groups corresponding to the 8 operators, with each operator’s group containing twice the number of schools that operator will manage. Within each of these groups, half of the schools were randomly chosen to be treated, with the rest serving as controls.

Since the composition of students may change across PSL and control schools in response to treatment assignment, we will sample students from 2015/2016 enrollment logs, which was created prior to community awareness about PSL intervention. Each student will be evaluated as part of her/his “original” school, regardless of what school (if any) s/he attended in subsequent years. Using this panel dataset, we can recover the effect of PSL schools under an Intention-to-Treat (ITT) framework. Under some assumptions, we can use instrumental variables to recover the Treatment-on-the-Treated (TOT)
