Together with the general "baccalaureat" leading to long higher education and the technical "baccalaureat" leading to short higher education, the vocational "baccalaureat" was created in 1987 with a view to democratizing and generalizing high school education. It must be noted that the French "baccalaureat" corresponds to the fourth qualification level (level 6 being the lowest level and level 1 the highest: master degree and above) in the trades nomenclature as acknowledged by the management and the workforce. However in practice, the newly created vocational "baccalaureat" is considered as a downgraded and relegation diploma in the guidance and orientation system. Based on interviews of school principals about their experience as heads and taking into account the highly hierarchical training offers distribution which de facto gives the vocational "baccalaureat" the last position, our contribution will aim at measuring the scope and limits of the attempted equity policies in education, inasmuch as the geographical location of vocational schools often testifies the spatial segregation which in turn mirrors a social and cultural segregation.
