This research aimed to study the objective geography of educational opportunities for regular high school of the educational state system of Rio de Janeiro s city, which implies two dimensions: the first one the Objective Geography of Opportunities based on the concept of Galster and Killen (1995) for which the conventional concept of equal opportunities should be expanded beyond the equal treatment of equals to include the geographical dimension in the process of opportunities which means that the geography can influence inequalities with serious social consequences. In this sense, it is important to think about space and its role in the development of social relationships. The city of Rio de Janeiro is characterized by large slums, many of them located next to the noblest city spaces - Rio s segregation model: physical proximity and social distance. Hence, is important to consider how its educational opportunities are distributed spatially. By specifying these educational opportunities we have the second dimension: high school. This level of education had a trend of many reforms which sometimes advanced in its democratization process and sometimes created obstacles. Besides, being a level of education is little access to large parts of society there was a lack of consensus about its role - introductory or professional. Aimings to map the objective geography of opportunities in the regular high school of the educational state system of Rio de Janeiro s city this job involved analyzing data related to education that are available in official surveys - Population Census 2010 and School Census 2012 - in order to characterize its current situation. This mapping was performed using computational tools called Geographic Information Systems (GIS). The results indicate that the objective geography of opportunities is affected by political and social forces, creating new dynamics.
