School failure is, at the international level, a problem that affects, most educational systems. In Spain, it is currently a current problem that remains unresolved. Therefore, our research aims to discover and analyze situations of school failure experienced by different agents with long experience in order to understand them and find out the possible responsibility of the school itself and the teacher. The methodology used in this research is qualitative in its focus on the phenomenological approach. The sample is constituted by the following: (a) active teachers; (b) retired teachers; (c) students who live school failure and (d) subjects integrated into the working world who experienced situations of school failure. The instrument used to collect information was the semi-structured interview and the focus groups, supported by a script designed and submitted to expert judgment. The results have been obtained from “content analysis” using the Nvivo11 Plus program. A wide overview of the main academic causes, incidents from the school and the classrooms that are involved in school failure is presented. Among the most relevant conclusions is that the school, with certain actions and in an indirect way, can lead to the construction of school failure.
