This paper focuses on professional foster parents who provide care for children removed from their family environment by court order. The practice of professional foster care entails a number of challenging situations that professional foster parents are often unable to cope with on their own. To support professional foster parents in managing such situations, a team of professional workers has been set up. The aim of the research was to find out whether professional foster parents cooperate with professional workers in solving the problems of a child placed in the professional foster family and also how they perceive the usefulness of a social worker. The research sample consisted of 203 respondents practising professional foster parenting, which represents almost one third of all professional parents in the Slovak Republic. The results showed that professional foster parents most often cooperate with social workers and a psychologists in solving the child's problems, and less often with other professional workers. Respondents also identified areas in which they found social workers useful.
