Abstract
Community-driven development interventions blend multiple components difficult to identify separately. The literature reports mixed impacts of these interventions. We designed and conducted a field experiment in 126 schools of the Angolan province of Kwanza Sul, aiming to distinguish the impact of the information and the collective action components of a scorecard system. Specifically, we explore a design with three treatments: (i) decentralized information to parents on the performance of schools, (ii) organization of meetings with parents without pre-set information on performance, and (iii) centralized information on performance through meetings with parents. Our measurement of outcomes includes: parent, school, teacher, and school principal surveys, as well as lab games and test scores. In the games, apart from standard lab games (trust, public-good), we develop a novel dictator game where teachers individually decide about sharing their endowments with multiple parents.

Primary Outcomes

Primary Outcomes (end points)
Our measurement of outcomes includes: parent, school, teacher, and school principal surveys, standardized student tests, as well as lab games and test scores. In the games, apart from standard lab games (trust, public-good), we develop a novel dictator game where teachers individually decide about sharing their endowments with multiple parents.
Important outcome variables from the parent survey are self-reported involvement at the school in terms of time and money invested and the relationship with the teacher, satisfaction with the school, teachers, management and behavior of other parents, as well as collective action indicators.
Teacher-related outcome variables from both the teacher and director surveys are self-reported performance outcomes (i.e., attendance), satisfaction with school, other teachers, management and behavior of parents, collective action indicators, as well as questions regarding the parental involvement of the parents of the 40 selected students answered by the relevant teacher. Other outcome variables related specifically to the director survey and include information about tasks and responsibilities, as well as the quality and quantity of relations with other institutions that support the school.
For the school level surveys, important outcome variables are those related to investments in the school facilities and resources (by parents), administrative data on student, teacher and school board performance (i.e., number of students that passed grade 6, attendance of teachers and school directors etc.), as well as parent involvement (i.e., existence of a parent committee).

Experimental Design

Experimental Design
We designed and conducted a field experiment in 126 schools of the Angolan province of Kwanza Sul, aiming to distinguish the impact of the information and the collective action components of a scorecard system.

Experimental Design Details
Randomization Method
The 126 schools were randomly allocated by a computer across the four treatment groups using blocks. The schools were organized in blocks employing village and a set of school characteristics, which included the number of classrooms, number students, number of teachers, and whether there are elections for a parent committee.

Was the treatment clustered?
Yes
