Young students’ mathematics performance is an important indication of their future academic success and career. Researchers have been searching for the factors that impact the learning and achievement of mathematics. This study seeks to explore the associations between math achievement of eighth grade students and their socio-economic statuses, amount of time they spend on homework, and their family sizes. Moreover, the effect of schools’ regions and minority rates have also been investigated in terms of students’ math success. A hierarchical linear model was used to run the related analyses.
