This article investigates the impact of working while in school on learning outcomes through the use of a unique micropanel data set of the standardized test scores of Brazilian students. The potential endogeneity of school performance and child work is addressed through the use of fixed-effects estimators. A negative effect of working on learning outcomes in both math and Portuguese is found. The effects of child work range from 5% to 13% of a standard deviation decline in test score, which represents a loss of about one-quarter to three-fifths of an average year of learning. Robustness checks confirm the main conclusions.
