The centralized school is also affected by the problem of logistics. If a
central school has a large catchment area, this can involve a lot of travelling
for pupils, which in turn may impair their ability to concentrate during the
lessons and also renders the school time-table less flexible for additional
tuition. In the Chinle Public School District (a Navajo Reservation), for
example, there are nine schools for 4559 children within an area of 7200
square miles, which results in four-hour bus runs for some of the children
(Liebe-Harkort, 1980). Mackay (1969) similarly reports that the children in
the Scottish Highlands often have to leave home at 8 am and do not return
until 6 pm.
