An analysis of the results in the provision of public education under different institutional contexts is carried out for Colombia where, during the decentralization process, different degrees of autonomy to manage education public expenditures have coexisted. The analysis is undertaken by using frontier analysis techniques, which allow us to estimate cost and production functions, in order to determine differences in costs and technical efficiency in the provision of education across regions. The results show that the strength of decentralization had a more positive impact on increasing enrollment than on the improvement of the qualiTY of education. It was also found, that high levels of cost and production inefficiency are present in different regions of the country, implying that savings in public expenditure and better educational results could be achieved if all local authorities could operate at the most efficient level.
