The current research aimed to study High School in two areas of Rio de Janeiro city through the relationship of youth and schoolmasters facing the issue of educational oportunities of High School. The research departs from the concept of Geography of Opportunity (Galster e Killen, 1995) to investigate the objective (offer of educational resources) e subjective aspects (values, expectations e aspirations) of educational opportunities. Firstly, the Geography of Opportunity of the schools of High School of Rio de Janeiro city was analyzed having as basys the data from Censo Escolar 2005, in which were identified two areas near slums marked simultaneously by relative inequality between supply and demand as well as by the proximity to major shopping centers. In this sense, a number of schools was selected so that a fied work could be carried out. The methodology involved visits to schools, observations, informal and semi-structured interviews, and the application of questionnaires. The results indicate that the geography of objective of opportunity can not be taken as inert, because on which focuses force fields as political and social determinations that are able to create new dynamics that as well interfere in the development of the subjective geography of opportunity among individuals.
