The aim of this book is to discuss the process of building the professional identity of basic education workers, identifying their relationship with schools and national education. The research carried out for the development of this work showed that basic education staff have achieved, through legislative norms and public training policies, instruments that corroborate both the overcoming of their historical invisibility and the construction of their professional identity. They are no longer seen as second-rate servants, but are now recognized by normative instruments as education professionals. This book fills a gap in academic production on the importance of this segment in the school environment and is aimed at basic education staff, students, teachers, educational managers, educators and other professionals who are interested in studies on educational policy, professional identity and the training process.
