The study of the localization of girls’ secondary schools in Jeddah shows that the school map is both a diagnostic and perspective tool for school policies. It is also a tool for research, for measuring accessibility and thus for helping decision- makers in the education sector (Ministry of education, regional education directorates, etc.) insofar as it makes it possible to visualize the scenarios of educational facilities. Through the present study, we have developed a map showing the distribution of the girls’ secondary schools in Jeddah. This map shows for some households a low accessibility to these schools. That has enabled us to propose facilities to reassure a certain equality of opportunity for access to secondary schools.
