Site-selection for schools in large cities such as Tehran is a complicated problem. A multiplicity of effective factors in locating schools and increase of urban living problems in Iarge cities manifests the necessity of the use of effective, advanced, and computerized methods for this purpose. The main objectives of this research to evaluate the pattern of spatial distribution of primary schools and to identify the bereaved zones of primary school and to them in the region 6 of Tehran. Attribute data were collected and stored using the available documents, and local data were collected and digitized using linear and digitizing maps in several layers. For each layer buffers were specified, then by giving weights for each buffer zone and their combination, spatial positions of the existing schools were analyzed. Finally, the optimum sites for establishment of new schools were proposed. Results of this research showed that the majority of educational buildings of primary schools are not located in suitable sites, and their sites do not conform with site-selection standards. The results of this research also showed that the use of GIS can be very useful for ananlysis and selection of schools sites.
