This document aims to provide evidence about the existence of different patterns in equality of opportunities in academic achievement during the last fifteen years in Colombia. The outcomes selected for measuring inequality are the scores obtained on SABER 11 in math as well as reading. It is found that inequality has grown around 11% in the country, and that this trend is common for all the metropolitan areas included in the analysis. Most of the increase found comes from factors related to the school market. The fraction of unfair inequality, conditional to the circumstances included in the definition of “types”, is higher than 20% of gross inequality in 2012.
