This study aims to investigate the influence of higher education on the changes in the personal and professional practices of a group of teachers coming from the lower classes. It also seeks to identify and analyze the factors that contributed to make these schoolteachers obtain school longevity. In addition it contributes to a reflection on the current policies of initial teacher education in higher education. As for teaching practice, the accounts by the group of teachers revealed important changes in their professional "habitus". However, the study also revealed some constants in their practices that seem to indicate that some of the problems experienced by the group of teachers, arising from their family and school background, have not yet been overcome by them.
