This paper provides empirical evidence on students' achievements determinants in Sub-Saharan Africa based on a sample of 26602 students from the ten countries that participated in the PASEC 2014 assessment. By using a two-level hierarchical linear model, I find that learning inequalities are primarily explained by differences in schools' characteristics. Furthermore, the estimation findings corroborate this result by showing the relevance of resources at the school level and how it affects students' performances depending on school type and location. Additionally, my results showed gender disparities and peer effects related to socioeconomic status, which disproportionately influence children from disadvantaged backgrounds.
