In this paper, intercultural sensitivity, personality traits and emotional competence of students of teacher studies in the Republic of Croatia are investigated. The goal of the research is to examine the level of development of intercultural sensitivity regarding multicultural experiences, personality traits and emotional competence. 235 students from all 7 teacher studies programs in the Republic of Croatia participated in the research. The data were collected anonymously through an online Google form during regular psychology classes at the teacher’s college. The following scales were used in the research: Intercultural Sensitivity Scale (ISS) by Chen and Starosta (2000), Big Five Inventory (BFI) by Veronica Benet- Martinez and Oliver Peter John (1998), Multicultural Experience Scale, Emotional Competence Questionnaire (UEK-45) by Vladimir Takšić (2002) and the Sociodemographic Variables Questionnaire. The data collected during this research were processed using the statistical data processing program Statistika 14.0 and Microsoft Excel. The results of the research show an above-average intercultural sensitivity of students of teacher studies and a significant connection between intercultural sensitivity and multicultural experiences: traveling outside the home country, using several foreign languages, contacts with members of other cultures. Research participants who had more travel experiences outside their country, who had knowledge of more languages and had frequent interactions with members of other cultures turned out to have a higher level of intercultural sensitivity compared to other participants. Also, the research showed that some personality traits and emotional competence have an impact on the level of intercultural sensitivity of future teachers. Research participants who have lower scores on the traits Openness, Extraversion and Agreeableness unexpectedly show a higher level of intercultural sensitivity, which is contrary to expectations. Research participants who have higher scores on the abilities of emotional competence, Perceiving and understanding emotions and Regulation and management of emotions have a higher level of development of intercultural sensitivity.
