[eng] This article focuses on the school-to-work transitions of Spanish youth. Herein,we study the pathways followed during a 10-year period by young people who dropped out of school without achieving any qualifications and who did not achieve any at a later date.This is a population aged 26-28 years old with an educational level of ISCED 0-1. The study adopts a pluri methodological approach that includes an initial qualitative phase whose main instrument was the biographical interview and a second phase with a quantitative focus in which data were collected using a questionnaire.The results show the effect of dropping out of education without qualifications on the pathways of the youths as well as their greater vulnerability in the current period of economic crisis, which results in a high percentage of the population that has no employment, education or training. This effect is even greater among women.This study highlights the difficulties associated to returning to education, the reproduction of educational exclusion in the population that did not obtain the diploma corresponding to compulsory secondary education, and a lack of public policies to support this specific population.
