The present document has a formative approach, which is governed through the process of documenting, systematizing, analyzing, reflecting and projecting the transformation of knowledge, skills, attitudes and values of school and professional practice. Theoretical, epistemological and methodological resources of the biographical-narrative research and the constructivist perspective were necessary to carry out this reconstruction process, resulting in the achievement and understanding of my training and being a teacher and the relationship with the influence of my relatives and acquaintances, as well as the context, initial education, the study of the Master's Degree in Basic Education (MEB) and its impact on my teaching practice, the experiences during the journey, the tasks and experiences outside the classroom, and even situations and circumstances external to the teaching profession.
