This study sought a better understanding of the impact of a mother’s participation in the labour market, on the academic performance of children in their primary school certificate examinations. The study used a recursive bivariate probit model in order to treat the endogeneity of the variable “mother’s participation in the labour market”. The data used in the study were drawn from the Integrated Regional Survey on Employment and the Informal Sector (ERI-ESI-2018). The results demonstrated that a mother’s participation in the labour market has a negative impact on the academic performance of children in their primary school years. These results inform us of the need to address the challenges faced by working mothers by providing them with the support they need to establish a balance between their professional and maternal responsibilities.
