The aim of this paper is to analyze the economic weight of secondary schooling in household budgets in the city of Kindu. In this study, we used the non-probabilistic occasional sampling technique of surveying households (individuals) who were available to answer our closed and open-ended questions. In formulating the closed questions, we opted for a binary choice to facilitate econometric data processing using Eviews 9.0 software. Schooling a child is a cost for households, especially for children at secondary level. In this study, we have shown that the cost of sending children to school is close to 80% of average household income in the town of Kindu, and that socio-economic factors are behind the increase in the weight of children attending school during the last school year.
