ABSTRACT In the Republic of Croatia, there is not a single overarching professional association for early childhood education (ECE) teachers. Instead, six regional ECE teachers’ associations are actively operating. Recognizing the shared responsibility for upholding professionalism, ECE teachers are proactively seeking a nurturing environment that fosters their professional growth and aligns with their practical requirements. This research was conducted with a sample of 206 ECE teachers in the Republic of Croatia and aimed to explore the role of professional ECE teachers’ associations in shaping the professional identity of ECE teachers within the country. To achieve this objective, a survey questionnaire was designed to assess motivation, self-perception, self-efficacy and attitudes of ECE teachers toward educational tasks and ECE teachers’ professional associations. The findings reveal that both education level and membership in professional associations are predictive factors influencing respondents’ perception of their profession and their professional identity.
