Mexico spends a little over USD 20 000 per student from the ages of 6 to 15. More precisely, expenditure per student is almost four times greater in higher education than it is in the lower levels of education and, because expenditure per student for each level of education is determined at the federal level, the same is true in Morelos. Studies based on PISA show that the quality of educational resources is most strongly associated with the incidence of low performance in mathematics at the country level, followed by the quality of physical infrastructure (OECD, 2013a).
