The aim of the study was to determine the structure of social competences of professional foster parents using the Social Competence Questionnaire A. Matczak (2001). The study included 167 professional foster parents carrying out family emergency tasks in the Śląskie and Małopolskie voivodships. Research results show that more than half of the respondents are characterized by an average, and more than one-third by a high level of social competence. Compared to the results of the general population, foster mothers have significantly higher competences on the intimacy scale, and foster fathers on the assertiveness scale. In comparison with representatives of other social professions (nurses, family assistants), foster mothers have significantly higher social competences in the intimacy scale compared to nurses. In comparison with family assistants, the results obtained are comparable.
