performance, as measured by the mean test score for secondary school graduates.
The positive effect was revealed before and after adding controls relevant for the
case of Moldova. Based on the results of the best specification, we conclude that
there is an optimal school size for Moldova, it is about 777 students. The results
of the current work can be used as guidance during network optimization agenda
