Public facilities have various types and functions to support people activities. Provision of public facilities in Indonesia is carried out on the base of population size and spatial approach, which for the development of new facilities used the scale and capacity of services analysis on related facility. This study aims to measures service rates of elementary school in the Malang, Surakarta and Banjarmasin City based on supply (school avalaibility) aspect, and then to identify spatial pattern of the services. As previous, the measurement was done with the administrative boundary as analysis units but then the grid/cell approach were used to obtain accurate results. Based on the analysis result, service capacity of elementary school in the Malang City defined by the mash/grid/cell approach was 271,75% meanwhile in the Banjarmasin City was 535,68% and Surakarta City was 1.510,4%. These results means that school in these three cities can meet the demand with more than 3 – 15 times than existing population size. The results also illustrates that people in these three respective cities can access elementary school not only in their administrative boundary but also they access school everywhere of their city areas.
