Using data from its national university entrance exam, we examined the relationship between armed conflict and student achievement in Afghanistan. Exploiting the province-year variation in exposure to conflict intensity, we estimated the relationship between conflict and exam results generally and by gender for all test takers from 2014-2019. Findings show that a one standard deviation increase in conflict intensity at the province-year level was associated with a 2.9 percentage point reduction in the probability of passing the exam, a 0.096 score point reduction in total exam scores, and a greater detrimental impact on women's exam results.
