BARRIENTOS MARIN, Jorge. School cover policy and academic achievement: the case of Medellin's concession program. Perf. de Coyunt. Econ. [online]. 2009, n.14, pp.159-171. ISSN 1657-4214.

In recent years the secretary of Education of Medellín started the Concession Schools Program for school-age children who were not covered by the educational public system. This program was designed to provide private educational management by means of public resources where public supply was reduced. In this work we are interested in investigating the impact of this program on students' academic achievement. To this aim we match individual at concession schools with those at public ones by computing the probability of attending concession institutions. In spite of the good reputation of the concession strategy we found that students at concession schools had a lower performance than their peers at public schools.
