Cultural diversity is important in every setting of life, but it can be even more critical when it occurs in education. Students around the world have equal rights to a quality education, so there are many benefits when institutions believe in the power of diversity. Intercultural dialogue can build and promote understanding within a society and between different societies. This dialogue contributes to demonstrating the value of cultural diversity and human rights. The dimension of diversity represents the first axis on which the contents of intercultural education are placed. It is about rendering social reality as composed of various elements. At the same time, on the axis of diversity is the pedagogical concern to offer the student the opportunity to communicate and cooperate with others within heterogeneous groups. They are meant to reflect the diversity of points of view, to familiarize the student with the existence of perspectives different from his own. The teacher must be "intercultural". This presupposes that he has intercultural experiences, learns consciously or incidentally, later applies the activities with the students and helps others in the learning process. In addition, it is fundamentally necessary for the teacher to be aware of his own culture and to perceive the mechanisms of his preconceptions, faith, moral principles and values.
