In the region, mean years of schooling were 10.8 in Panama, 9.9 in Nicaragua, 8.8 in Costa Rica and in Belize, 7.5 in Honduras and 7.3 in El Salvador; the Panama, Costa Rica and Honduras values carry the table's 'e' mark. With another source and definition, Guate en Datos reports 6.26 average years of study for the population aged 15 to 64, last among the eight countries it compares (Panama 10.44, Costa Rica 9.12, Honduras 7.51).
