This present study comes to investigate teachers' views on what constitutes teacher professionalism and whether these views are influenced by gender, age, educational level and teaching experience. Both a qualitative and a quantitative research approach were chosen. Three teachers were interviewed, whereas 83 teachers completed the questionnaire. According to the findings, professionalism is related to the teacher's knowledge, personal and interpersonal skills. In addition, a large proportion of participants associate professionalism with mastering basic communication skills, developing problem-solving strategies and utilizing appropriate teaching methods. Finally, emphasis is put on developing a culture of collaboration between colleagues and between teachers and parents.
