Musical activities play an extremely important role in the overall development of children. Therefore, the goal of this research is to examine the attitudes of preschool teachers towards musical activities in kindergarten and their self-assessment of competence for conducting such activities with regard to professional qualifications and years of work experience. The survey was conducted via an online survey on a sample of 329 participants, preschool teachers from all Croatian counties. For the purposes of the research, a questionnaire consisting of three parts was constructed: Questionnaire of general information, Attitudes towards musical activities in kindergarten and Self-assessment of the competence of educators for conducting musical activities. The results of the research confirmed that educators of preschool children who have more years of work experience, compared to educators with fewer years of work experience, have more positive attitudes towards musical activities in kindergarten. Furthermore, educators of preschool children who have a higher level of education, compared to educators with a lower level of education, have more positive attitudes towards musical activities in kindergarten. Years of work experience did not prove to be a significant predictor of teachers' self-assessment of educational competencies for conducting musical activities in kindergarten. The results of the research confirmed that self-assessments of educators' competences for conducting musical activities differ depending on the level of education of the educators.
