Parental education, occupation, and income have a major impact on students' academic achievement as they outline access to resources, learning environments, and educational goals. Together, these socioeconomic elements support the growth of both cognitive and non-cognitive abilities, which is why they are so important in determining child’s academic journey. The present study aimed at finding out socioeconomic roots of academic achievement by analysing impact of parental education, occupation and income on the academic achievement of secondary school students. The sample consisted of 643 secondary school students from various schools of Greater Mumbai. The results of the present study revealed that there is a significant difference in the academic achievement of secondary school students on the basis of their parent’s (mother’s and father’s) education, occupation and income. Study concluded that students having highly educated parents performs better academically as compared to the student having uneducated parents, students having highly placed (professionals) parents performs better academically as compared to the students having unemployed parents and students having high income earning parents perform better academically as compared to the students having low income earning parents. For internationalization to be successful, internal educational disparities must be addressed. Disparities in academic performance are caused by a variety of factors, including parental occupation, education, income, and socioeconomic status. To transform India, we must first enact policies that fortify the foundation before we globalize the educational system.
