The education reform implemented since September 1, 2017 has caused a great confusion in society. The first issue is the educational value of actions taken at school. In accordance with the provisions of educational law, upbringing means supporting a child in development towards full maturity in the physical, emotional, intellectual, spiritual and social sphere, and should be strengthened and supplemented by activities in the field of prevention of children and youth (art. 1, item 3 of the Education Law Act). New educational and preventive programs are being created in educational institutions, and should refer to the content of the new core curriculum. What priorities will be included in these programs depends on the creative activities of teachers. The article is an attempt to reflect on the important tasks of school in the context of equality education, resulting from the belief that “All human beings are born free and equal in dignity and rights”. (Art. 1. of the Universal Declaration of Human Rights). The reflection presented refers to both legal and ethical aspects of the teacher's work. It describes the methodological solutions that can be used in the class's educational program or the school's preventive and educational program. Teacher support in the area of anti-discrimination activities is a response to the need to promote at schools equal treatment and respect in a socially diverse world.
