Inequality in education in Costa Rica: The gap between students in public and private schools. An analysis of the results of the Programme for International Student Assessment (PISA)

This article presents the main results of the Programme for International Student
Assessment (PISA) for Costa Rica in 2009 and then goes on to analyse the gap
between the scores of students attending private schools and those attending public
schools. However, the estimation of an education production function using these
data shows that this gap is not entirely attributable to whether schools are public
or private, but that instead the students' family environment, personal traits and, in
particular, the student's grade level at the time that the PISA test was taken are all
quite influential.
