The initial formation of teachers constitutes a complex process aimed at a professional formation of the teacher that will foster the skills and competences necessary for the profession and thus, developing resignifications, unique experiences and challenges of beinging a teacher. To facilitate this path, the Programa Institucional de Bolsas de Iniciação à Docência (Pibid), within the framework of a national policy, offers a space for the student to articulate the theory seen in the classroom with the practice experienced in the future work locus, therefore, an important space in the initial formation of the teacher. In this sense, this research aimed to understand the importance of the PIBID / Pedagogy for the initial formation of teachers, with a focus on teacher professionalism. We used as methodological strategy a qualitative research with the pibidians of the pedagogy course of the Universidade Federal Rural de Pernambuco (UFRPE), Universidade Federal de Pernambuco (UFPE). In the data collection we used the documentary analysis of its legal framework and semi-structured interviews with the subjects of this research. After the data collection, we organize and categorize them to arrive at the interpretations and inferences that culminate in the final results presented.
