This paper deals with issues concerning the right to difference, diversity and processes of school exclusion/ inclusion. Specifi cally, the invisibility of the process of social exclusion in schools suffered by the child that works in the rural school environment, as well as the processes of professional training, when despite the diffi culties found, the individual moves away from their cultural and productive contexts and enrolls in technical courses in urban schools. These are the issues mentioned in two previous studies: the fi rst examines the relationship between the work and schooling process of the child worker studying in the rural area, and the second looks at the representation of teachers regarding students from rural environment, of a technical course - integrated mode - in farming, offered by a Federal Institute for Education, Science and Technology.
