The objective of this article is to evaluate the intercultural sensitivity of teachers working in culturally diverse classrooms, and to analyse differences in intercultural sensitivity based on the gender, age, training (advanced training courses), and intercultural experience of the teachers. A quantitative approach with a comparative descriptive design was chosen. The Intercultural Sensitivity Scale was used, composed of 24 statements, which were responded to by 50 teachers. The results show that teachers possess moderate intercultural sensitivity and that the highest rated competencies are trust and attention to communication.
