This dissertation entitled Perceptions of elementary school teachers on domestic violence against children and adolescents: study of the notification process in a public school in the city of Manaus, AM. Is the result of a qualitative research, which sought to find out what a group of elementary school teachers understand as domestic violence against children and adolescents and how they stand in relation to the mandatory reporting of suspected or confirmed cases of this type of violence established by the Statute of Child and Adolescent (ECA). For its realization we designed a questionnaire that was answered by 19 teachers who work in the early grades of basic education in a public school located between the northern and eastern areas of the city of Manaus. The analysis of responses revealed that teachers who participated in this study know little about domestic violence and the majority only associated it with physical aggression, identified by body marks. Regarding knowledge and position in relation to what is established by the ECA, only 31.57 per cent of teachers were aware of proper procedure, 26 per cent of them knew partially, while 21 per cent of teachers said they knew nothing about the procedure. As for mandatory denunciation, 63.25 per cent of teachers responded that they were unaware of it.
