Schools are organized into clusters, usually consisting of a central, relatively well-resourced school and several smaller satellites. The latter may be one-room schools with one-room school with one person teaching more than one grade in the same class.
Satellite systems have to address difficult problems in managing progression through grades. The núcleo system in Bolivia aims to ensure that children complete their basic education at the consolidador, or central school. Another approach is to create satellite schools that provide a full primary cycle, such as those developed for remote rural communities in Burkina Faso (UNESCO, 2010: 192).
