Research on teacher training, also in the field of early childhood education, has shown the problems faced by teachers when they start their professional careers. Teachers mention above all, the difficulty in transposing the theory learned in their undergraduate course to practice. Which training model can prepare the teacher to meet the expectations described in the guidelines given to them on working with children at this early stage of schooling? Is there a unique model? The dissertation conveys as the object of the investigation the experience of the College Level Teacher Training Course offered by the Institute of Higher Education Pró-Saber. The objective is to analyze a training proposal based on Paulo Freire s democratic conception of education, which has as its guiding elements: the on-the-job development, the cultural formation and the principle of inverted symmetry. The course has as a particularity of being dedicated exclusively to pre-school professionals who are working in public institutions. The methodology of Madalena Freire, pedagogical coordinator of the Course, presents methodological tools on which the work is based: guided observation, reflexive recording, evaluation and planning in a continuous cycle. The institution is presented with the aid of methodological resources such as exploratory reading of internal documents, interviews with the pedagogical team and alumni, observation of the classes and questionnaire sent to the graduates. It was sought to understand what repercussions a training with these characteristics could bring to the pedagogical practice of teachers. The fieldwork was carried out with the support of authors who develop research in the area, which covers specific concepts about teacher education, children s education and the teacher s cultural development, among them: Maurice Tardif, Antonio Nóvoa, Isabel Lelis, Sonia Kramer, Luciana Ostetto and Cristina Carvalho. The research data showed that a training that prioritizes a process of authorship, in which knowledge is built collectively, and that may offer wide access to different cultural expressions in a reflective perspective, contributes to the teachers appropriation of their own practice, to their feeling more secure, more appreciated and more committed to education as a broader political project.
