This research examined the reasons for the differences in the academic performance of school learners, and makes reference to economic, social and cultural capital theory in explaining educational imbalances in society. Many researchers have conducted studies on the factors contributing to the academic performance of learners at various levels of schooling have been undertaken. These researchers have come to the conclusion that the academic performance of learners is affected by numerous factors, namely, gender, age, learners' schooling, family’s socio-economic status, residential area of learners, the medium of instruction in schools, tuition trends, hours spent on studying on a daily basis and accommodation in hostels (Petersen, 2010:15). There is a popular saying in south-western Nigeria, that “if the parents’ financial status is good, the reflection of it will show in the child”. This study is focused on the academic performance of learners at the secondary school level and investigates the influence of economic, social and cultural capital on their academic performance. This study aims to determine which factors contribute to the poor academic performance of rural secondary school learners in south-western Nigeria and then, based on the findings of the research undertaken to make recommendations regarding what could be done to improve the academic performance of these learners. The mixed-methods approach of combining both qualitative and quantitative approaches to accomplish the aims of the research were used. The population consisted of four secondary schools, four school principals, 16 teachers, 40 parents and 120 learners. According to the results of this research, we can see that the social, cultural and economic capital of parents is a powerful determinant with regard to motivating their children’s education. / Educational Studies / D.
