A look at the percentages for completion of secondary education in six countries (Brazil, Chile, Ecuador, El Salvador, Guatemala and Nicaragua) between 1990 and 2009 shows that socioeconomic inequality in terms of secondary-school completion increased in five countries (Brazil, Ecuador, El Salvador, Guatemala and Nicaragua). The only decrease was in Chile, which by 1990 was already in a better position than the others and where the potential for increasing the completion rate in the highest income quintile was lower (ECLAC/UNICEF, 2013). Both cycles are usually included in the term secondary education or high school.
