The present research aims to know and understand how the life trajectories have made men choose the teaching profession related to Early Childhood Education, besides analyzing the process of insertion and permanence in the daily life with the children and to perceive how the memory and the experiences contributed to the development of the professional identity of these teachers. As a scenario, we have the Carioca Municipal Education Network, which is considered the largest Network in Latin America and had as a landmark the classification and convocation of male teachers in specific competitions for Early Childhood Education in the years 2010 and 2012. Such research has a qualitative character and used the methodology of Life Stories linked to the interviews, as a means of obtaining data that answered the different questions that permeated the study. In the course of the investigation, a mapping of the Teachers Men who work in Early Childhood Education was developed, looking at different perspectives: National, Regional, Municipality of Rio de Janeiro and its Regional Education Coordinations (CREs). Fifteen men from different CREs were interviewed, dealing with different subjects, among them: Formation, Choice of Profession, Daily Life in Childhood Education, Gender, Masculinities, Teaching Identity, among others. It should be pointed out that we will not have a denunciation character, as used in many studies, but we will consider different events as relevant aspects in the constitution of the teaching and personal identity. We have as theoretical framework the studies of Louro (1998), Connell (1995), Scott (1990), Nóvoa (1995), Huberman (1995), among others.
