In the last few years, capital expenditure represents the greatest proportion of annual public expenditure in general programmes of upper secondary education (fluctuating between 10% and 18%). In the 2005-13 period, the proportion of capital expenditure has grown considerably in technical-professional programmes (from less than 2% to more than 8%) and less son in primary education (from about 4% to about 8%). Also, as depicted in Figure 3.14, in 2011, capital expenditure as a proportion of total expenditure in public institutions was lower in Uruguay (4.5% in primary education, 3.5% in secondary education) than in the average OECD country (7.7% in primary education, 7.1% in secondary education). For the same year, capital investment in school education was more significant in Argentina, Brazil and Peru than in Uruguay.
