The aim of this research was to study the current level of preschool teachers' partnership competence in the aspect of interacting in the teaching staff. During the research, questionnaires and statistical methods of analysis were conducted. The results of the study show that 82% of the respondents describe the psychological climate in the team as moderately favourable, 6% note its high level, 9% feel low favourableness, and 3% see it as unfavourable. The conducted research revealed a positive moderate correlation between the partnership competence level and the psychological climate level in the team of preschool teachers. Therefore, a positive psychological climate, characterized by mutual understanding, support and openness, contributes to creating a favorable environment for partnership interaction. When teachers feel comfortable and supported in the team, they are more inclined to work together, share experiences and provide mutual support. The area of further research is to identify the relationship between the professional development of teachers and their partnership competence, as well as to study the impact of distance learning on partnership interaction between teachers and ways of its development in the digital environment.
