Violence is a serious social problem, and when children are involved in violence, whether they are direct victims or witnesses of adult violence, adults are expected to be held accountable to protect children. Protection from violence is guaranteed to each of us by many laws, regulations and conventions. But despite this, neither adults nor children are completely protected from this horrible phenomenon in society. In the social consciousness, children have been considered the property of their parents for long time and have often been exposed to various forms of abuse. Although society's consciousness is far different today, violence against children still exists and we are surrounded daily by news of violence against children, abuse and neglect. Modern man, given the knowledge he possesses, should be more responsible for life around him, for life as a whole. It is necessary to especially protect the most vulnerable, and that is certainly children. Special responsibility rests with professionals working in upbringing and education as they should be among the first to promote children’s rights. Therefore, in this paper, the competencies and behaviours of preschool teachers in the case of violence against children are investigated. Their beliefs, attitudes, behaviours, and competencies were examined for the purpose of making ethical judgments. Research has shown that educators are aware that violence is a serious social problem. They are also aware of their role in detecting violence against a child. They are able to recognize different forms of violence. Despite this, the research showed that educators would need additional education in this area.
