This study focused on school going children’s educational performances of working nonworking mothers. Factors including parents’ highest level of education and their profession, family income, family size and the number of school-going siblings in the family were considered as the explanatory variables of educational performances. Based on the primary data collected through a random sample survey of the students from two schools in Chittagong University campus and applying the regression analysis of the ANCOVA model, this study found that mothers’ level of education and family income have a significantly positive impact on students’ academic performances though the mothers’ employment status has a negative impact except those who are employed in teaching profession. Thus, this study suggests that the ideal profession for mothers is teaching which plays a vital role on their children’s educational performances than the other professional mothers.
