Performance differential of students in military schools: The case of public schools in ceará

Abstract

The performance differential between students from military and civilian schools can-not be attributed only to the school effect, since factors such as family characteristics, accumulation of knowledge and the selection process established by military schools can generate a bias in performance. This work investigates whether there is still a military school effect in empirical models of proficiency a la Hanushek (2016), once these factors are controlled. A longitudinal admin-istrative database for public schools in Ceará was used, following students in fifth and ninth grades, who were selected by CEM (Coarsened Exact Matching) matching method related to performance in base year. It was found that the lack of control for selection bias and former performance increases the military school effect by one and a half times in traditional models. However, even controlling these factors, the military school effect is still significant.
