In 1992, Mexico's federal government signed the ANMEB agreement as part of a series of strategic public education reforms. The agreement decentralized the education system, making state governments directly responsible for providing basic public education, in an attempt to reduce marked regional disparities in educational levels. Now that sample sizes are large enough to allow reasonable empirical analysis, I examine several indicators used to measure the characteristics of education in each state. The aim is to assess whether there is sufficient empirical evidence to affirm that the agreement has contributed to improving education levels and reducing disparities among the states.
