Starting from the modern understanding of giftedness as a domain-specific personality quality, research was conducted to determine the moral competencies of gifted students in different domains and to examine the psychometric characteristics of the adapted version of Moral Competency Inventory - MCI on a sample of 473 respondents. The results indicate that the original four-factor structure has been confirmed and that the MCI is a reliable and valid instrument suitable for application in other educational contexts as well. It was found that students gifted in different domains differ from each other when it comes to integrity and that this property is most developed in students gifted in the field of sports, then music, mathematics, and finally, visual arts. Such results indicate the importance and need for continuous professional guidance and intentional moral education of gifted students.
