This paper presents some cross-country comparative measures of efficiency in public education, using existing data for European countries. It also presents an overview of different approaches to the question of efficiency of investment in public education and the measurement thereof. Although non-parametric methods have been used in some studies on investment efficiency in the education sector, the approach adopted here extends previous research by conducting the analysis combining the data from different sources. The variables used in the empirical analysis are constructed from different databases (the joint Unesco-OECD-Eurostat data collection, IEA or OECD’s databases) which are all designed so that data is comparable across countries for the same reference year.JRC.G.9-Econometrics and statistical support to antifrau
