Smarter Teachers, Smarter Students? Some New Evidence from Sub-Saharan Africa
We study the effect of teacher subject knowledge on student achievement in mathematics and reading by using a data set from six sub-Saharan African countries. By using an estimation based on within-teacher within-student strategy, we can avoid a potential endogeneity bias. In most estimations and most countries, we do not find a significant teacher knowledge effect. The main reasons are teacher absenteeism and the need to focus on core knowledge.
