A previous research showed that the professionality of teacher's from 5th to 8th grades is developed in different levels and that there are certain patterns in the teachers' reactions up against daily school conflicts. This present study intended to verify if there would be differences in the professionality levels between the teachers. Fourteen teachers from 1st to 4th grades of a public school in a city from São Paulo State were interviewed about hypothetical stories, each one containing a problem to be judged/solved; the analysis complied with piagetian criteria. The results indicated that these teachers' depositions are distributed by the same levels previously found and the reaction ways to the conflict are just the same. It was conclude that the teacher's professional development occurs in a sequence of hierarchical levels and in order to make the professional schemes progress and improve it is fundamental to be aware of the presented obstacles, first step for its solution.
