In this qualitative study, we sought to debate about some complexities present in Youth and Adult Education (EJA) in situations of deprivation of liberty. The education offered in these spaces is one of the categories of EJA and is guaranteed by international and national regulations, thus constituting a right and not a benefit. The research aims to understand through a documental analysis the conceptions about education present in the normative that constitute this category. In addition to the normative analysis, we will deepen the study through semi-structured interviews conducted with teachers, who work with this specificity of teaching, aiming to understand their conceptions about the prison school. Nine teachers were interviewed through the bola de neve or snowball sampling. We use a very heterogeneous theoretical framework that includes curriculum theories as well as criminological theories, which we consider necessary to address this issue and assume a critical and post-critical character, with the poststructuralist view, to perform the analyzes. Thus, we identified that the prison and the school are permeated by dynamics of control and disciplinary power. Prison controls and exercises power over the school through a series of practices and the school, according to the teachers, stands as an opponent of this system. However, it was also possible to identify that despite this opposition, the school also exercises a form of disciplinary power over the prisioners. This form of disciplinary power is also expressed through some conceptions about curriculum, Political-Pedagogical Project and Education for Human Rights.
