Preschool teachers are those who are expected to implement the educational process with effective practices by making utmost use of the basic dimensions such as the educational programme and educational setting, considered to be amongst the determiners of a high-quality preschool education. As in all other teaching specialties, the characteristics that preschool teachers need to possess are also open to debate. Consensus is reached, however, on the view that teachers' previous experiences influential on their professional choice, their knowledge of child development, their beliefs, and their self-esteem are essential for highquality learning settings. The main purpose of this study is to examine the preschool teachers' personal characteristics of effective preschool teachers through vignettes. The second aim is to determine the relationship between effective preschool teacher characteristics. Purposive sampling method was used for the selection of the participants and 54 teachers volunteered to take part in the study. For data collection, a semi-structured interview form composed of various short stories and based on the scenario approach was developed by the researchers. The vignettes were created in a way that reflected the 12 different characteristics of a teacher (passion, perseverance, willingness to take risks, pragmatism, patience, flexibility, respect for diversity, creativity, authenticity, love of learning, high energy, and sense of humour) proposed by Colker (2008). The holistic rubric and correlation analysis were used for the analysis of the data. The study concludes that preschool teachers demonstrate a sufficient degree of flexibility but prove inadequate in terms of love of learning and pragmatism. The findings of this study are expected to shed light on preschool teacher education policies. As a result of the research; that the majority of the participants were enthusiastic and authentic; they need to be improved in terms of being creative; pragmatists and love of learning are inadequate. However, there is a significant negative relationship between being enthusiastic with being a pragmatist and being creative with having a high energy score; a significant positive correlation was found between the perseverance and the appreciation of diversity.
