This paper investigates whether providing financial education in elementary and middle school grades improves students' financial proficiency and actual behavior. We use a cluster randomized control trial to evaluate a pilot program implemented in 101 Brazilian municipal schools in 2015. The findings show positive impacts on financial proficiency, mainly among middle school students, and suggestive evidence of improvements in short-term behavioral outcomes. However, the analysis indicates that the program did not impact students' school achievements in both the short and longer terms, which suggests that the program's effects were not strong enough to shift students' behavior decisions.

Experimental Details


The intervention consisted of four financial education textbooks tailored to different elementary and middle school grades. The curriculum was conceived to introduce the role of financial education in students’ daily lives by developing financial concepts such as savings, consumption, and waste; making students able to identify situations related to financially responsible attitudes, estimate the budget necessary for financial projects, and find relevant information in the press media for decision-making in finance. The pilot was run in municipal schools of Manaus, the capital of Amazonas state, and Joinville, one of the largest cities of Santa Catarina state.

Experimental Design

Experimental Design
We used a stratified cluster randomized trial to evaluate the impacts of the pilot in the municipal schools of Manaus and Joinville. We used the school census data of 2014 to select a sample of 201 eligible schools. We then stratified the sample by the municipality and three school types: schools that only offer elementary school grades (first to fifth grades in Brazil), schools that only offer middle school grades (sixth to ninth grades in Brazil), and schools that offer all elementary school grades, totaling six strata. We randomly assigned 101 schools out of the 201 to receive the program in the school year of 2015. In agreement with ENEF, we selected grades 3, 5, 7, and 9 to be part of the evaluation.
