The populations living in situations of social vulnerability, especially people with a history of street situation, have historically been constituted in an invisible way before the society, for example the impossibility of being regularly enrolled in regular schools for not having a residential address. The research aimed to analyze how the condition of school learner is constituted subjectively in adult students with a history of street situation. The present work was based on the Theory of Subjectivity and Qualitative Epistemology, both developed by González Rey. The research was developed through the constructive-interpretative methodology.
