This paper presents the outcomes of qualitative research aiming to describe the deinstitutionalisation experience of children up to 7 years old in social welfare homes from the perspective of social workers (N=5). Conducted interviews revealed the information on the organization of the deinstitutionalisation process system, which is unplanned and unsystematic. It has been deduced that there is few professionals and they are overloaded, namely the kind of service provided by the institutions has changed, thus increasing full-day and half-day stays, along with introducing consulting service for helping families. There has been a decrease in the number of institutionalised children, while the capacity has been fully reached at the same time. Moreover, social workers have pointed to the issue of foster care underdevelopment and changes closely connected to the role of social workers who lack the formal support and now have much more work, which has become pretty diverse. In deinstitutionalisation process they cooperate well with foster carers and adopters, whereas they cooperate sometimes bad sometimes well with CZSS (Centre for Social Welfare), as well as with the parents of institutionalised children. The challenges of deinstitutionalisation are numerous so social workers list the challenges at system level due to sluggishness of court cases, act amendments, hard pursuit of foster families and, again, increase in workload. Furthermore, social workers face challenges of children who are not easily adopted, as well as with resistant parents of institutionalised children.
