The text identifies relations between the theme of confession and the narration extant in the recent registers of occurrences of a public school in Curitiba, based on post-structuralist analytical references. These registers relate cases of students considered by the school as problematic and undisciplined and contain 517 occurrences for the years 1998 and 1999. In the records of the registers, we focus on elements that produce criminal and sinful scenarios in daily school life, with regard to that which they may express in terms of confessional practices of a juridical and religious type. From the juridical point of view, confession is seen in some of its possible articulations with other elements present in the narrative of the registers, like evidence, proof, clues, making part of a kind of daily mini-inquiry of the school, and in so doing producing accusations, crimes and punishment. From the religious point of view, the confessional dynamic is seen through these registers as a part of the process of "circulation of sins", in which the traditional battle between Good and Evil, between God and the Devil, is presented and, in a certain way, taught.
