Education plays an important role in the development of society. The service area for schools is generally considered at a distance coverd in 10 minute walk. There are four tehsils of Khushab which are Khushab, Nurpur Thal, Quaidabad and Noushera. There are some areas with no government schools for girls. In previous research works serviceability has been analyzed with indices such as number of schools (Mladenka and Hill, 1997; Omer, 2006), but these indices do not show the correct results (Ohio and S.Jiong, 2007). However, it is difficult to find serviceability without analyzing the spread of schools (Tsou, 2005). This study focuses on the spatial spread of schools and the accessibility of people to schools integrated with the road network. Accessibility is the basic facility, which helps people move anywhere and reach destinations (Gregory, 2009). It is also considered the proximity of one place to another (Pooler, 1995).
