Slovenia has one of the highest shares of the population aged 25 to 64 to have completed at least upper secondary education, and ranks high in international educational achievement tests. Nevertheless, in some areas, reforms could significantly improve performance and equip the labour force with the skills most in demand in a rapidly changing economy. In particular, low student-teacher ratios, small class sizes, and a high share of non-teaching staff suggest that there is room for improving spending efficiency. Rationalising teaching and non-teaching staff would also free up valuable public resources that could be redirected towards underfunded aspects of the education system.
