The teachers formation is assuming prominence position in the relative discussions to the public politics, as well as in the investigations and publications of the area. The study of the subject of the teachers continuous formation involves a considerable number of authors that point the inadequacy of the initial formation for the teacher s professional development and the need of considering the teacher s knowledge and the school as lócus of educational formation. That consent puts in prominence the need to think a continuous formation that values the practice developing by the teachers in the daily school as the knowledge that comes from the researches accomplished in the university, in way to join theory and practice in the formation and in the construction of the teacher s professional knowledge. In this perspective as backdrop, I sought, in this work, to characterize the teachers continuous formation that happens at the public fundamental school of the municipal district of Rio de Janeiro. The initial supposition is that formation happens in formalized experiences of continuous education, but also, and, especially, in the daily of the school space. In this perspective, the focus of the research was directed to the continuous formation that happens inside the school, in the different moments and levels in that there are changes among teachers and of these with other professionals of the school. To accomplish the objective of characterizing the teachers continuous formation, I investigate and to compare the teachers continuous formation in schools of fundamental teaching organized in cycles, in the dimensions macro and analysis mesossocial. In the dimension macrossocial, the data of SAEB 2001 were used (National System of Evaluation of the Basic School) to describe and to explore some of the characteristics of the continuous formation offered by the municipal public schools frequented by the students of Rio de Janeiro. In the dimension mesossocial, it was made a study of case of the continuous formation offered at a public school of fundamental teaching of our municipal district.
