A special effort was made for rural schools (the “piso rural” programme), which provided a special compensatory subsidy to small rural schools, based on a criterion which was different from that governing allocations in the general system: the fewer the pupils, the greater the subsidy.
Especialmente expresivo es el llamado "piso rural", subvención especial compensatoria a las escuelas rurales de pequeño tamaño, asignada con un criterio distinto al del sistema general: mientras menos alumnos más subvención.
