For instance, the following figures compare results by department (equivalent to provinces in that country) of an assessment of the reading abilities of all primary school teachers in Guatemala, with the incidence of poverty and concentration of Indigenous peoples in each of these departments. By making this comparison, this simple method reveals that the most disadvantaged children are being taught by the least qualified teachers. The three departments in which teachers had the lowest reading test scores are the three departments with the highest incidence of poverty. They are also amongst those departments with the largest concentration of indigenous people.
